Why do I not have hot water?
May, June and July are the coldest months on the Gold Coast, and no-one wants to start the day with a cold shower in winter. Unluckily for some clients of Whywait Plumbing who are not Service Partners it is in these months they go to the shower and question why do I not have hot water?
Unfortunately, hot water systems are a case of out of sight out of mind. Continually where hot water systems are concerned, there were warning signs that there was a problem. Over the summer months, hot water problems are overlooked as the demand for higher temperature; hot water is not a critical consideration.
Several warning bulletins in Queensland have been issued by the QBCC and Queensland Health advising homeowners that their hot water systems need to be maintained and serviced frequently.
AS/NZS 3500.4:2018 Heated Water Services
The Australian standard that all hot water installation is based around is AS/NZS 3500.4:2018 Heated water services that are an integral part of the National Construction Code of Australia issued by the Australian Building Codes Board and it is all legal requirements in Queensland.
In AS/NZS 3500.4:2018 there is Appendix M which provides guidelines for the operation and maintenance of your hot water system which is below:
M1 SCOPE
This Appendix provides guidelines for the operation and maintenance of a heated water system.
M2 GENERAL
In order to ensure maximum performance and length of operation, water heaters should be inspected periodically.
M3 MAINTENANCE OF HEATED WATER SERVICES
Heated water services should be maintained in accordance with the following:
(a) Water treatment units: Where installed, water treatment units should be inspected periodically to ensure proper operation.
(b) Water vessels and tanks: All vessels and tanks should be inspected and cleaned periodically, and in accordance with any requirements of the regulatory authority.
NOTE: The frequency of periodic cleaning depends upon the quality of the supply water, design, materials of construction and the pipe system. Combinations of materials giving rise to corrosion should be avoided.
(c) Valves: The following valves should be inspected periodically to ensure proper operation:
(i) Temperature/pressure-relief valves.
(ii) Expansion control valves.
(iii) Thermostatic mixing valves.
(iv) Tempering valves.
(v) Other associated valves/devices.
(d) The requirements of AS/NZS 3666.2, where applicable.
Common reasons for why do I not have hot water
Below are listed the most common reasons we attend to clients jobs who call up to as why do I not have hot water? Listed are elementary troubleshooting ideas that you can undertake yourself to resolve or understand why your hot water is cold:
- blown fuse or circuit breaker – replace the fuse or reset the circuit breaker and if it blows again it’s probable there is a fault with your element or thermostat, and you need to call Whywait out to repair
- Energex relay switch failure – this is not the easiest to detect but if you are on off-peak rates and there are no obvious electrical faults or water leaks then its worth a phone call to your energy supplier to check whether the relay switch has failed to activate in your area
- defective relief valve – most relief valves on the side of the HWS only have a life span of around 3-5 years. Still, they can jam open so first check if you see water running from it by pulling the lever up and then easing back down again. If water continues to run then you need to call Whywait out to service the unit
- no water at all – this is when you wake up turn the tap on and cold water flows, but there is no flow from the hot water. Frequently this a failure of the non-return or isolating valve and a quick way to check is to turn the handle on the valve all the way off and then all the way back on. In many cases, the hot water will simply begin to flow again. However, if there is still no flow you need to call Whywait out for repairs
- water fluctuation from hot to cold – there are several reasons for this occurring, but the most common is a faulty tempering valve. There is nothing you can do to solve fluctuation other than call Whywait and read our information on tempering valves
- water leaking from hot water tank – there is only a maximum of 7 possible points on an HWS tank where there are joints that can possibly leak. Only 2 of those are concealed in the housing so if the water is leaking from the tank and its not from the visible water connections you need to call Whywait for service to check the HWS. In all likelihood, if the hot water tank is more than ten years old then its a 50/50 chance you need a new one installed
DIY warning
The above reasons are the most common problems you will experience with why do I not have hot water. As you can see above, there are only a few simple DIY solutions when you have no hot water.
A word of warning though. Please never open up the housing near the bottom of the tank where the electrical connections are as they are all live wires inside there and therefore very, very dangerous.
Whether you have a solar, heat pump, gas or electric hot water system they do need periodic maintenance so for all hot water problems call Whywait Plumbing now on (07) 5580 4311 as we guarantee a same-day rapid response for hot water problems.

Hay Fever Season
Once the footy finals are over, we know it’s spring, as the weather warms and evening barbecues become the norm. But for many people, spring is a time to be dreaded. That’s because the advent of spring means its hay fever season for one in five Australians.
Hay fever season comes in stages over the spring and summer. The first stage will be in October/November when windborne pollens of plants and grasses cause allergens. When the pollens become trapped in your nose or eyes, they release their allergens. Fortunately, the pollen allergens are benign, but for one in five of us, our body misreads them as being harmful and fights back. This results in our body producing mucus to expel the pollen allergens.
As the body fights the pollen allergens watery, itchy bloodshot eyes along with a runny nose and sneezing are the most common symptoms of what we refer to as hay fever.
Filtered Water & Hay Fever
As proactive prevention should always be the #1 action, you should start with installing a Taqua built-in filtration tap. The filter built into the Taqua tap will remove chlorine and impurities from your tap water. Best of all for hay fever sufferers a Taqua tap is guaranteed to retain the minerals your body needs in your tap water.
Your #2 action in hay fever season should be to drink 800 ml of hot water every day from your Taqua tap. Drinking hot water at 50 ºC assists in easing common hay fever symptoms such as sneezing and a runny nose.
This simple action of drinking hot filtered water will make your life more comfortable if you suffer from hay fever plus will assist your general health due to its detoxing effects on the body.
Your #3 action in the hay fever season is to rinse your eyes regularly with cold water to flush out the pollens. Using the filtered cold water from your Taqua tap will ensure that you are not washing chemicals such as chlorine directly into your body.
Filtered Water & Vegetables
We all know that eating fresh fruit and vegetables assists in our overall health, particularly in the hay fever season.
Did you know washing your fresh fruit and vegetables with ordinary tap water loses many of their valuable minerals?
The reason for this mineral loss is due to the free chlorine in ordinary tap water that reacts with the minerals in fruit and vegetables, causing the minerals to break down. In fact, 10% – 30% of all minerals are lost due to washing fruit and vegetables in tap water.
Using a Taqua built-in filtration tap with its veggie spray function is the perfect solution to wash fruit and vegetables to ensure they retain all their vitamins.
Cooking with filtered water from a Taqua built-in filtration tap is a simple way to improve the taste, smell and colour of your food.

Like For Like Online Pricing
In Queensland, if you see online website prices or are quoted over the phone a price for like for like hot water service replacement for an electric or gas storage tank¹ system, don’t believe one word of it. The prices are a sham designed to scam you into calling them to book in the job.
The prices quoted above are about right for a like for like installation. The problem is probably only one person in a hundred would qualify for this pricing.
I can 99% guarantee² you will not receive that price for a legally compliant hot water service replacement issued with a QBCC Form 4 compliance certificate.
The pricing and terminology are deliberately deceptive and are a scam. I will categorically state the prices are absolutely bullshit and lies, for most installations.
Going back over ten years ago yes all plumbers undertook like for like hot water service replacement when replacing electric or gas storage hot water tanks. Simply this was legally compliant at the time and accepted industry practice.
What is like for like hot water service replacement?
“Like for like” installation is frequently seen as the basis of pricing on websites as a starting point for pricing for replacing your hot water system. They usually use confusing terminology stating that the pricing is starting from what is a low price for a like for like installation. They then vaguely define like for like as being for replacing the hot water system where it is:
- the same type of hot water system as the old hot water system
- that the hot water system is being installed in precisely the same location as the old hot water system
- that the new hot water system is the same size as the old hot water system
- that the new hot water system has the same electrical requirements as the old hot water system
Of course, it’s not explained clearly like I have using sixty-seven words. Instead, they tell all of that in one compressed vague sentence of thirty-four words.
And naturally, there will be getting out of gaol clauses that are again vague and confusing. These clauses will state that other costs may be incurred because:
- you have individual site installation requirements to ensure your like for like hot water service replacement is compliant with all regulations
- if you require any additional valves installed that were not in the like for like scope of works
- if you request removal and disposal of the old hot water service
- if you require a new concrete slab or support base
- if you need any additional piping to be installed
- if you require any additional electrical wiring or any electrical work other than disconnecting and reconnecting
- any work what so ever that is required to the existing plumbing, electrical or gas infrastructure to ensure your like for like hot water service replacement is compliant with the council, state or commonwealth regulations
- any additional labour or equipment required due to site access conditions
All of the above are standard requirements on any hot water system replacement to meet the legal requirements of the Plumbing and Drainage Act 2018 and the Plumbing and Drainage Regulation 2019.
The whole reason all of the above and many more possibilities are excluded from a like for like hot water service replacement offer is to fool you.
Ultimately every existing hot water service installation has individual requirements when installing a replacement hot water service. That is why a website price or a quote over the phone is meaningless.
You can only ever get a correct price for replacing your old, leaking hot water service after a comprehensive site inspection. In the small print on all websites that quote like for like replacements, they almost always state somewhere that pricing may change once their plumber undertakes a site inspection
Why Is A Like for Like Hot Water Service Replacement Non-Compliant?
The photo below is a Dux 50 litre electric hot water service that has been replaced like for like. Except it is utterly non-compliant because:
- the hot water pipes are not insulated
- the relief valve is not insulated
- there is no pressure reduction valve
- there is no cold-water expansion valve
- there is no tempering valve
- as it is an internal installation, there is no hot water tray to contain water leaking from the tank, pipes or valves
- there is no automatic shutoff valve to cut off the water should there be a leak
- there was no QBCC form 4 given to the property owner
There is no such thing as a like for like installation. There is definitely no such thing as an exemption for a QBCC Form 4 compliance certificate if you are only undertaking a like for like installation.
What is required to replace a leaking hot water service?
If your hot water service is leaking and requires a replacement then in all likelihood it will be at least eight years old and probably much more. I can guarantee the infrastructure regarding valves and overflow drains will not be compliant with the legal requirements that we must now adhere to.
We recently replaced the nine-year-old Siddons heat pump unit in the photo below that was no longer functioning with a CO2 Smart Heat Pump hot water unit. Even though it was only installed nine years ago, it was utterly non-compliant with the current requirements.
Since 1 July 2019 every hot water service whether its a new installation or a replacement installation must be installed in complete compliance with AS/NZS 3500.4:2018 Plumbing and Drainage Part 4: Heated Water Services.
This standard, along with several other standards, is called into law via the Plumbing and Drainage Act 2018 and the Plumbing and Drainage Regulation 2019.
The installation of a new or replacement hot water service must comply absolutely with the standard and in particular Section 5 Installation of Water Heaters – General Requirements. The scope of this section states explicitly: This Section sets out general requirements for the installation of water heaters, their location, support, cold water service valves, the vent or drain lines, and the first 2 m of heated water supply piping.
This section sets out exactly how all hot water service installations must be undertaken. Nowhere does it refer to a like for like hot water service replacement.
No professional, reputable plumber will quote you on a like for like installation as they know it does not exist. Companies who market on this basis are engaging in deceptive and misleading marketing to get their foot in your door, so they can then upsell you.
Any plumber who starts telling you that you can get a lower price with a like for like replacement is simply a liar.
Every hot water service replacement must have a Form 4 compliance certificate lodged with the QBCC and the appropriate fee paid. Ultimately this is for your protection as compliantly installed plumbing, and drainage installation is about protecting your health.
Replacing a hot water service does not involve guesswork it’s about merely obeying the law and being compliant with the Plumbing and Drainage Act 2018. If you have had your hot water service replaced as a like for like replacement you need to report it now to the QBCC as an offence complaint. The plumber who undertook the installation will be required to return and complete the installation in compliance with the Plumbing and Drainage Act 2018 at his cost.
If you are uncertain about your hot water service replacement or need assistance contact us on (07) 5580 4311 and we will give you our opinion on how to proceed.
¹ : Replacing an instantaneous gas hot water unit is frequently like for like as it is a straight disconnection and reconnection to the gas connection and to the water pipes. In most instantaneous units, there is no need to install or replace valves as all management of temperature is undertaken inside the unit.
² : The only time I have seen a compliant like for like replacement is when a faulty hot water service has had to be replaced within the first 12 months after installation and was already fully compliant. This is a genuine like for like replacement under the manufacturers guarantee where the client pays nothing and where everything concerning the plumbing and electrical infrastructure was already compliant.

QBCC Form 4 Plumbing Compliance Certificate
We often receive questions from clients regarding why we charge them for Form 4. The straightforward answer is that it is required by law.
The Form 4 system for plumbing and drainage work has existed for over two decades.
Initially, licensed plumbers had to submit Form 4 to local authority plumbing inspectors. For those on the Gold Coast, this meant submitting the form to the City of Gold Coast’s Plumbing and Drainage section when replacing part of the sewer house drain, water main, or hot water service.
In 2012, legislative changes mandated plumbers lodge Form 4 with the Department of Housing and Public Works through the Plumbing Industry Council (PIC). This was the first time a fee was introduced for lodging a Form 4, which amounted to $25.90. In 2014, the Queensland Building and Construction Commission (QBCC) assumed responsibility for the Form 4 process as part of their role in overseeing occupational plumbing licensing.
Once Form 4 is submitted, it may be subject to a random compliance audit to ensure the work adheres to the Plumbing and Drainage Act 2018 and the Plumbing and Drainage Regulation 2019. This process guarantees that work is carried out to the highest standards, safeguarding everyone’s well-being, health, and safety.
Whywait Plumbing has always been a proponent of the Form 4 process, as it ensures that all work on your property is compliant and registered with both the QBCC and the City of Gold Coast. In the event of a significant insurance claim involving plumbing failure, an accessor can easily trace the work to confirm that it was performed legally and in compliance with regulations.
In essence, Form 4 serves to protect homeowners.
Which areas of plumbing & drainage work are classified as notifiable work?
The definitions of notifiable work were updated on 1 July 2019 to ensure clarity and usability and establish cost-effective plumbing laws and regulations for both plumbers and property owners.
Twelve primary categories of notifiable plumbing and drainage work necessitate a Form 4:
- Extending water supply pipes – involves work on water reticulation pipes other than fire services in existing buildings.
- Extending or removing a fire service – applies to class 2-9 buildings with development approval as per schedule 2 of the Building Act 1975.
- Existing sanitary plumbing – pertains to work in existing buildings where sanitary plumbing is removed, replaced, altered, or extended.
- Existing sanitary drainage – concerns work on existing class 1 to class 10 buildings involving extension, replacement, alteration, or removal of any part of the sanitary drain system (excluding a combined sanitary drain). This also applies to extensions or alterations to a class 1 building.
- Temperature control devices – includes work with thermostatic mixing valves (TMVs) or tempering valves in existing buildings that require installing, replacing, or removing a valve. This also applies to extensions or alterations to a class 1 building.
- Water heaters – involves work in existing buildings requiring installing, replacing, or removing a hot water heater. This also applies to extensions or alterations to a class 1 building.
- Backflow prevention devices – work with testable backflow devices or dual check valves in existing buildings that require installing, replacing, or removing a valve. This also applies to extensions or alterations to a class 1 building.
- Greywater treatment plants – pertains to work involving installing a greywater use system that includes a greywater treatment plant installed in a sewered area where the plant generates less than 3kL of greywater daily or for replacing a greywater plant.
- Fixtures in class 1 or class 10 buildings – include work required for installing a new fixture or relocating an existing fixture in class 1 or class 10 buildings. This also applies to extensions or alterations to a class 1 building.
- Fixtures for class 2 to 9 buildings of 1 or 2 storeys – applies to all work other than sanitary drainage required for installing or relocating a fixture, provided the work is for an existing class 2 to 9 building up to two storeys above ground.
- Sanitary drains – involves sealing a sanitary drain after the connection point to the council sewer or a treatment plant.
- Sealing supply pipes – includes work to seal a water supply pipe after the council water meter, provided the work is for an existing class 2 to class 9 building.
The QBCC provides easy-to-understand guides on notifiable work and the definitions of building classes as outlined in the Building Code of Australia, which can be downloaded below:
Form 4 notifiable work compliance
Every reputable professional plumber I know wholeheartedly supports the notifiable work system. This support ensures that homeowners and property owners can trust that all work carried out on their property adheres to the required standards.
If you have had plumbing or drainage work done and have not been provided with a Form 4, as shown above, and the work falls under the listed categories, you should report it to the QBCC immediately or call them at 139333. High-quality plumbing and drainage work is essential for protecting your health.
If you are uncertain or need assistance, don’t hesitate to contact us at (07) 5580 4311; we will offer our opinion. Ultimately, all plumbing work is not about guesswork but compliance with the law, specifically the Plumbing and Drainage Act 2018.

A burst flexi hose is a job we attend to almost every day. In all likelihood, you will have multiple flexi hoses in your home. They will exist commonly in both residential and commercial buildings under the kitchen sink, under the bathroom vanity basins, under the toilet cistern and under the laundry tub. Invariably when we attend to a burst flexi hose it has been damaged during installation causing kinking and has further experienced corrosion. Almost always the burst flexi hose was a time bomb waiting to happen. The braided stainless steel “simple to install” flexi hose has over the last 10 years replaced copper pipe connections to taps and toilet cisterns. Unfortunately, the braided stainless steel flexi hose has not lived up to expectations and delivered on the rust protection anticipated. In our experience, a burst flexi hose is caused by:
- incorrect installation with multiple kinks in the braided stainless steel
- stretching of the flexi hose to make the connection fit
- chemical attack from household cleaners
All of the above can create the perfect storm scenario in causing the braided stainless steel to corrode and rust. It then is just a matter of time until the stainless steel braiding fails which allows for the inner liner to burst. Here at Whywait Plumbing, we are now installing a polyamide hi class water hooker from Abey Australia which is the most technologically advanced flexi hose we have seen come onto the market. The 
Abey polyamide hi class water hooker cannot rust or corrode as it uses polyamide braiding that is similar to the Kevlar used in bulletproof vests. The connectors are manufactured from brass alloy so the entire flexihose will never rust even if its continually in contact with chemicals such as chlorine.
We are confident you will never experience a burst flexi hose once we install the Abey polyamide hi class water hooker as they literally cannot rust and cannot kink but best of all they come with a 15-year rust resistant warranty. Kinking is often the cause of a burst flexi hose but cannot occur with the Abey polyamide hi class water hooker. Kinking is simply poor installation as a result of over tightening the connector which twists the stainless steel braided hose. This over tightening creates 
pressure and tension in the braiding which frequently results in the inner liner bursting through the braiding and rupturing. The Abey polyamide hi class water hooker has a simple design to ensure that it is anti-kink. When we install the Abey polyamide hi class water hooker we are able to use two spanners to counteract any twisting that results in kinking.
Most of the flexi hoses currently used have an inner lining manufactured from EPDM which has the potential to absorb and release harmful chemicals such as 
chlorine into your drinking water. This ability to absorb chemicals also results in a potential burst flexi hose. With the Abey polyamide hi class water hooker the inner lining is manufactured from Softpex Core. The Softpex Core inner liner gives a superior mechanical performance to EPDM guaranteeing a longer life due to its higher tensile strength, higher abrasion resistance, higher working water pressure and non-corrosiveness. The extensive age/stress testing undertaken resulted in an amazing 0% failure rate.
We strongly recommend that you get us to check your flexi hoses every year for rust and/or corrosion and that they are replaced every five years. This will give you the peace of mind in knowing that the flexi hose in your home or business is not rusting and about to explode releasing water at 25 litres every minute that it flows. Rust is the #1 enemy of a braided stainless flexi hose.
When we replace your existing stainless steel flexi hoses with the Abey polyamide hi class water hooker we guarantee you will get:
- superior strength and corrosion resistance
- tested and WaterMark approved for use in Australia
- superior tensile strength
- superior working water pressure
- a superior mechanical performance with the Softpex core inner liner
- a 15-year rust resistant warranty from the manufacturer
As always we must caution you that installing or replacing a flexi hose is not a legally compliant DIY installation and under Queensland law must be done by a licensed plumber. You need to be aware that undertaking a DIY installation has the likelihood of making your insurance coverage null and void and the manufacturer’s warranty null and void if the flexi hose bursts and causes damage. Don’t wait for the ticking time bomb of your existing stainless steel braided flexi hoses to strike! Call us now to get us to upgrade you to the Abey polyamide hi class water hooker.

My Hot Water Service Needs Replacing!
Which Hot Water Service Should I Buy?
Besides renovating your home replacing your hot water service is likely to be one of the major costs your household will face. With the cost of heating hot water ranking second in dollar spend for household electricity costs, Whywait Plumbing believes it is imperative that you are well informed before making any decisions on your new hot water service.
With the plethora of makes and models available, the push for energy efficient solutions and a range of next generation water heaters on the market it is now more important than ever to do your research to ensure you select the best option available for your families hot water needs.
If you have been thinking “which hot water service should I buy?”, Whywait Plumbing will help by explaining the options available in the marketplace.
Electric Hot Water Service
Electric hot water services are the most common form of heating hot water. They consist of a storage tank with an element that is thermostatically controlled. As hot water is drawn off and cold water enters to replace it the element comes on to reheat the water.
Benefits
- Ideally suited for like for like replacement.
- Available in a large range of makes, models and sizes.
- Readily available for same day installation.
- Reasonable up-front cost.
- Suitable for connection to off-peak electricity tariffs.
Limitations
- Higher daily running costs unless connected to off-peal tariffs
- Limited capacity if connected to off-peak tariffs, so you have the possibility of running out of hot water should the demand for hot water exceed the capacity.
Gas Hot Water Service
Gas hot water services come as either the traditional storage tank, which works in a similar way to electric but uses gas rather than electricity as it’s source of energy, or instantaneous gas hot water services which only activate when a hot water tap is turned on. Instantaneous gas hot water services have become more popular than the traditional storage tank due to their superior efficiency. If you do not have reticulated natural gas in your suburb then LPG models are available.
NB: It is imperative that the correct sized unit is installed for your house to ensure adequate delivery of hot water.
Benefits
- Available in a large range of makes, models and sizes.
- Reasonable up-front cost.
- Provide on demand hot water.
- Energy Efficient Solution
Limitations
- LPG running costs can be expensive if hot water demand is high.
- Need to refill gas bottles if running on LPG.
- Whilst natural gas is cheap to run there will also be service fees charged by the energy retailer.
Solar Hot Water Service
Solar hot water services capture and retain heat from the sunlight and transfer this heat to the water stored inside the tank. Solar hot water services are available in both roof mounted and split systems. Roof mounted solar systems have both the tank and solar collectors or panels located on the roof and split systems have the solar collectors or panels on the roof and the tank on the ground with a circulating pump connecting the two. The heart of a solar hot water system is the collectors as they trap the heat and transfer it to storage, so for optimum operation they need to be located on a north facing roof. Solar collectors are available as both flat panel or the more efficient evacuated tube system.
Benefits
- Energy efficient Solution.
- Low to no running costs.
- Available in a range of makes, models and sizes.
- Reduced greenhouse emissions.
- Eligible for government rebate.
Limitations
- Higher up-front cost
- Dependent on sunlight for heating so operation is affected by the weather and may also need to boost electrically during the winter months to ensure an adequate supply of hot water.
- Any hot water used at night will not be reheated until the next day unless the electric booster is on.
- Must still be connected to electricity so will be charged a small service fee by the energy retailer whether you use electricity or not.
- Alters aesthetics of the property.
Heat Pump Hot Water Service
Heat pump hot water units are designed to deliver hot water day or night no matter what the weather conditions. A heat pump unit uses a fan to draw in ambient air which is absorbed by a refrigerant gas. As the warm gaseous refrigerant circulates through the system it passes through a compressor where it’s pressure and temperature rise. The hot refrigerant then passes through a heat exchanger which heats the water. The refrigerant is cycled back into the system, and the hot water is pumped into the storage tank.
Here at Whywait Plumbing we recommend the Sanden “Eco” Hot Water Heat Pump the most energy efficient hot water heat pump currently on the market as certified by the Australian Government Clean Energy Regulator.
Benefits – Sanden Hot Water
- Low running costs proven to use 20% of the electricity costs of electric storage tanks.
- Available in a range of sizes.
- Energy efficient.
- Reduced greenhouse emissions.
- Manufactured for Australian conditions.
- Fast recovery rate.
- Eligible for government rebate.
