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:
This Appendix provides guidelines for the operation and maintenance of a heated water system.
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
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.
What do you do when your roof is leaking?
A Gold Coast leaking roof is common as our weather is notorious for extreme rain events. Summer storms are the most likely time you may experience a leaking roof. Heavy rain accompanied by strong winds can create the scenario for a roof leak that cannot be replicated. Like all plumbing problems, a leaking roof will not go away.
Signs that you have a leaking roof
heavy rain causing gutters to overflow can create a Gold Coast leaking roof especially if you also have blocked stormwater drains
A leaking roof does not always show up when the rain is pouring down. Obviously, the water inundation occurs during the storm, but signs of the roof leak can show up much later.
Water dripping through the light fittings or a crack in the ceiling creating a wet patch is a visible sign you have a Gold Coast leaking roof. Some of the obvious signs that you have a leaking roof are:
- water drips occur while it is raining or shortly after the rain stops
- water is running down interior walls
- the water drops will be a dirty brown colour resulting in dirty wet stains on gyprock ceilings
- your gyprock ceiling develops a bulge
- gyprock ceilings or walls become mouldy
- ceiling insulation is wet
Water damage from a roof leak
A Gold Coast leaking roof is an unwanted water feature that can create multiple hazards in your home or business premises that include:
- damage to the timber trusses that hold your roof up
- bulging to the gyprock ceiling that can result in it falling down in sections that are inundated with rainwater
- damaged roof insulation
- damage to electric lights and wiring
- create a breeding ground for mosquitos
Health risks from a leaking roof
An obvious risk from any water leak is the occurrence of mould and mildew. An intermittent roof leak that creates dampness is more likely to create the perfect breeding ground for mould in carpet and gyprock.
Mould spores from wet carpet, gyprock ceilings and walls can transfer quickly via air conditioning that can cause respiratory issues for everyone who comes in contact.
What you should do if your roof starts leaking
A roof leak that suddenly occurs as a result of storm damage will usually take you by surprise. The first thing to do if you experience a sudden roof leak during a storm is to move furniture, electrical appliances and any valuable personal belongings away from the leak area. If you cannot transfer your furniture, try to cover it.
Once you have moved your personal belongings, try to put a bucket under the water drip to contain the mess from the dripping water. Having further buckets is a necessity so you can empty the buckets. If the water is spreading use towels to contain it and try mopping the area to soak up as much water as possible.
How to repair a Gold Coast leaking roof
A roof leak needs to be investigated and repaired as soon as you become aware of it. Roofing repairs are not DIY jobs and squeezing silicon all over a roof achieves very little. A roof can be a dangerous place with falls from roofs by DIY warriors accounting for a large number of hospital admissions.
There are no quick fixes with a leaking roof. A leaking roof can be leaking in more than one place, and it is a process of elimination to solve the roof leak. You need to be aware that your house insurance will cover you for storm damage. However, if the water damage is attributed to your negligence due to you ignoring a previous leaking roof, there is a strong possibility they will reject your insurance claim.

Your Gold Coast water bill issued by the City of Gold Coast as a Water and Sewerage Rate Notice arrives every three months. Currently, every water meter is manually read every three months with your Gold Coast water bill coming soon after. The cost of water is set every year as part of the budget process with the detailed current water pricing for 2020-21 available from Gold Coast Water.
What are the costs on your Gold Coast water bill?
For most homeowners who use around the average daily water usage of 451 litres, the highest costs in the quarterly Gold Coast water bill are their sewerage and water access service charges. If you look closely at your water bill you can see that you have the following access charges:
|Sewerage access charge per quarter
|Water access charge per quarter
|Total Access Charges per Quarter
The usage charges per kilolitre as measured by your water meter are made up of council charges and Queensland Government charges as below:
City of Gold Coast water per kilolitre
|Queensland Government water per kilolitre
|Total Cost of Water per Kilolitre
In reality, even if you did not use one drop of water, you would still pay for water and sewerage access service charges of $234.05 every quarter or $936.20 every year.
In our experience, the average water use of 451 litres or 0.451kL per property is not an accurate guide to your water use. Most homes with more than one occupant will use 1-2 kL every day. Remember your water usage will vary every day based on the number of occupants at home each day, and their water use behaviours. That is why we recommend you read your water meter weekly as that will give you a better guide about your average consumption but will also alert you to a potential water leak.
The real cost of water dripping from a tap
What will cause your usage charges to blow out is having leaking water. Leaking taps and toilets are frequently overlooked and put off to another day. A dripping tap that drips one drop every second will use 40 litres of water a day. The reality is that it becomes 280 litres a week and then 1214 litres a month and then 14560 litres a year. This is all water charged for on your Gold Coast water bill that you never utilised for any useful purpose.
If we translate the litres wasted to the cost of water, then the numbers become real.
|Cost of a Dripping Tap at 1 drip per second
||Residential Cost at $4.212 per kL or 1000 litres
||Business Cost at $8.662 per kL or 1000 litres
1.66 litres per hour
|40 litres per day
|280 litres per week
|1214 litres per month
|14560 litres per year
The real cost of a leaking underground water main
A dripping tap or running toilet you can visually sight but the real killer to your Gold Coast water bill is your underground water main pipe leaking. For residential users, these are usually leaking polypipe water mains that were never installed correctly when the house was built. Only occasionally is a water leak apparent and bubbling to the ground. Most of the time they are a silent Gold Coast water bill killer leaking 24/7 undetected.
There is no real average for any leaking water main because it depends on the type of break in the pipe and what the incoming water pressure is. Currently, we have a small leak where we have water monitoring installed that is leaking on average of 44 litres per hour, so we use that as a basis for what a leaking water main will cost on a Gold Coast water bill.
|Cost of a leaking underground water main at 44 litres per hour
||Residential Cost at $4.212 per kL or 1000 litres
||Business Cost at $8.662 per kL or 1000 litres
|44 litres per hour
|528 litres per day
|3696 litres per week
|16016 litres per month
|192192 litres per year
A leak at 44 litres per minute is only a small leak. It is highly unlikely to show up bubbling to the ground unless it is directly under the grass in a shallow trench. Even looking at your water meter, it will not be evident unless you are testing your water use at the meter by checking for a water leak.
How much does a leak cost per litre
We have always recommended that you test your water usage through your water meter every month. By having comparable figures, you will soon ascertain whether you have a leaking pipe.
We have always recommended that you install an AquaTrip water leak detection system after your water meter. An AquaTrip Water Leak detection system with an integrated automatic shutoff valve supplied and installed by Whywait Plumbing is a permanently installed leak detection protection system that quietly protects against leaks 24/7. It is a one time only insurance payment.
With our modern leak detection methods, it’s a much easier job to find a leak but unless you have an AquaTrip installed or use our water monitoring service you will still pay for a lot of lost water before you become aware of the leak.
If you think you have a leak contact us because every litre that you lose is costing you $0.004212 for residential properties or $0.008662 for businesses on your Gold Coast water bill. If you believe that is inconsequential, we have just rectified a leak for a business client that was in a 40mm underground pipe that was leaking 96 kL every day, which is 96000 litres every 24 hours. This leak was costing $831.55 every day.
It is illegal to install a douche spray or bidet spray in Queensland unless it complies with AS/NZS 3500.1:2018 clause 12.2.3 below which classifies bidet toilet seats and douche sprays at toilet seat douches.
12.2.3 Toilet seat douches – Where the douche outlet, in all positions, is at least 25 mm above the overflow level of the pan, backflow prevention is not required. Where the douche outlet, in any position, is less than 25 mm above the overflow of the pan, a high-hazard backflow prevention device, conforming to AS/NZS 2845.1 or AS 2845.2, shall be installed. This device shall be either part of the douche or installed separately.
It is entirely illegal to undertake a DIY installation of douche spray or bidet spray despite what you may read on social media.
Yes, they can be legally installed by a plumber provided they are installed with compliant backflow prevention valves and registered with Form 9 at City of Gold Coast or Logan City Council plus lodgement of Form 4 with Queensland Building and Construction Commission. These requirements are not optional; they are required under law as per the Plumbing and Drainage Act 2018.
Illegal bidet seat attachments
Unfortunately, there are advertisements everywhere on social media or websites promoting DIY such as My Bidet Australia. The product they advertise as an easy install toilet seat bidet is illegal. They promote on their website as – Quick and Easy Installation: Includes everything you need including tools to get your bidet up and running in minutes. Easily attaches to and detaches from any standard two-piece toilet.
The reality is the product has no WaterMark certification. As the photo illustrates clearly on their website, the dual nozzles are deep inside the toilet bowl, creating a high backflow risk. This is categorised as high risk as back-siphonage can occur through these nozzles allowing contaminated water from the toilet bowl to be sucked into the potable or drinking water supply.
The toilet seat bidet from My Bidet Australia sells online for $99, which is an indication of its quality. The price should be a warning enough as to how good this product is likely to be as good quality WaterMark approved bidet seats such as a Toto Washlet start at around $1199.00 in Australia.
The old saying you get what you pay for applies absolutely for this dangerous product. It is frightening that they state on their website – Upgrade your bathroom with beautifully designed bidet attachments, featuring water pressure control knobs. We use high-quality parts that are built to last. They are constructed with high-pressure faucet quality valves and metal/ceramic core. Common sense dictates you cannot produce high quality for $99 that complies with Australian Standards.
Unfortunately, this product is being advertised everywhere on Facebook and Google. Currently, if you do a Google search for a Toto bidet seat the first result in Google AdWords is incredibly for not Toto but My Bidet Australia. It truly is a case of buyer beware and why you need to check it is approved for use in Australia with a WaterMark certification.
What does backflow mean?
Backflow is simply the reverse flow of water. When we refer to it in plumbing terms, it is stopping contaminated water being drawn back into the water supply system that we all use for drinking. In terms of an illegally installed douche spray or bidet spray, this can occur when the water pressure drops significantly. If nozzles or sprays connected to the water supply are in contact with a contaminated water supply in a toilet, there is potential for that contaminated water to be sucked into the drinking water supply. In simple terms, it is like you sucking on a straw.
There are two ways that backflow contamination will occur because of a water pressure drop:
- Back-pressure occurs if there is an increase in the downstream pressure, which creates a reversal of the normal direction of the water flow.
- Back-siphonage occurs when there is a drop in the supply pressure, thereby creating a negative pressure situation in the water supply. Commonly this will happen if the water is suddenly turned off or there is a dramatic increase in demand such as water used for fire fighting.
With a bidet seat, douche spray or bidet spray backflow contamination is possible and if occurring it is classified as high risk. This is why all of these products by law must be:
- installed by a licensed plumber
- have WaterMark certification
- have a testable backflow valve installed such as an RPZ valve
- have a Form 4 lodged with QBCC
- have a form 9 lodged with the local water authority
All of the above are requirements under the law; they are not optional extras.
What does high hazard mean?
High hazard is the highest rated hazard in the cross-connection hazard rating in AS/NZS 3500.1-2018, which is covered in Section 4 Cross-Connection Control and Backflow Prevention. As Licensed Plumbers, we know how serious this section is in ensuring that our drinking water is not contaminated and potentially life-threatening. Clause 4.3 below lists all three ratings:
4.3 CROSS-CONNECTION HAZARD RATING
Cross-connections are rated using three degrees of hazard, as follows:
(a) High hazard Any condition, device, or practise that, in connection with the water supply system, has the potential to cause death.
(b) Medium hazard Any condition, device, or practise that, in connection with the water supply system, has the potential to endanger health.
(c) Low hazard Any condition, device or practise that, in connection with the water supply system, constitutes a nuisance but does not endanger health or cause injury.
The high hazard rating is not a scare tactic when we talk about an illegal or a non-compliant bidet seat, douche spray or bidet spray it is a health issue with the critical wording being potential to cause death.
As Plumbers, we are not over sensationalising the dangers of DIY installation of a bidet seat, douche spray or bidet spray. We are just telling you this is the legal requirements as per the Plumbing and Drainage Act 2018.
Can a DIY installation effect insurance policies?
Yes, any plumbing fixture installed in your home or business can null and void your home and contents insurance policies.
Any bidet seat, douche spray or bidet spray that is not installed by a Licensed Plumber or does not have WaterMark certification has the potential to flood your home. A burst flexihose on these dodgy products can flood your home very quickly.
ACCC and Government warnings
We all understand that COVID-19 has caused a great deal of uncertainty and angst, but a DIY installation of a toilet bidet seat or douche spray or bidet spray is merely breaking the law. DIY of any plumbing fixture has potentially dire consequences, and with products such as the toilet seat bidet from My Bidet Australia, you are risking severe illness or death.
It has become so intense of a concern that the Australian Consumer Competition Commission (ACCC) has issued an alert concerning the supply and installation of bidet products. The ACCC, in consultation with the ABCB or Australian Building Codes Board and Standards Australia, has published a joint warning, COVID-19: Supplying and installing bidet products on the Product Safety Australia website.
The ACCC, the ABCB and every state government has become alarmed that the COVID-19 pandemic has seen a dramatic increase in the purchase of toilet seat bidet douches, handheld bidet sprays and trigger sprays, and other bidet type products that are connected to toilet water supply valve are being installed as a DIY project.
The critical message of every alert issued by every state government is that the installation of any bidet product connected to the drinking water supply must be undertaken by a licensed plumber and must hold WaterMark certification.
