Plumbing innovations have always been the norm in the plumbing industry. Innovation is change and is always about better ways of doing the same thing.
When I started my apprenticeship the clearing of a blocked drain started using a plunger and was at least a two-man job using 1m long drainage rods. The rods were screwed together and manually pushed slowly down the drain until we hit the blockage. Clearing drains this way frequently took 3-4 hours.
Plumbing innovations mean that we now clear a blocked drain with state of the art high-pressure jetrodding technology that was unknown 20 years ago.
Innovation is always about change, but at Whywait Plumbing we have always been at the forefront of plumbing innovations. We have always lead change as Gold Coast plumbers from the purchase of our first high-pressure water jetting unit in 1992 or installing vehicle tracking systems or introducing guaranteed upfront pricing in 1999.
What we always considered was developing and improving our way of solving your plumbing problems is now referred to as disruptive innovation. I agree disruptive innovation is the new term in business in the 21st century. But it’s not new it’s just a new way of talking about improving our methods and practices using the latest technology.
Change is the norm, but it just appears to be frantic to an outside observer with online banking, online shopping, online flight bookings and so the list goes on. At least with plumbing, it can’t be done online except for those DIY enthusiasts who believe Google Plumbing has all the answers.
The level of disruption through plumbing innovations has impacted all plumbing installation and maintenance has been significant starting with:
- Increasing use of prefabrication of bathroom and kitchen modules off-site where the plumbing is all undertaken in a factory, transported to the site and connected up to a water and drainage connection.
- Continual advances in sustainability with the advent of low flow toilets, low flow taps, waterless urinals and recirculated hot water.
- Advances in energy efficient products with heat pump hot water units, solar hot water, instant hot water and underfloor heating.
- All of the different materials we now use in the pipework, relining of existing pipework, CCTV cameras to inspect pipes and pipe jointing methods where welding is now obsolete.
- Excavation methods with advanced technologies in hydro excavation and tracking and locating of underground services.
The ongoing changes in technology in the plumbing industry are disruptive if not embraced. I agree that plumbing innovations cause a significant difference in how we undertake to solve plumbing problems and how the plumbers at Whywait work now.
Ultimately plumbing continues to be about protecting the health and safety of the community for now and the future to ensure we have good quality water and sewer systems in our buildings.
Replacing Your Hot Water Service – How Will You Know What’s Right For You?
When replacing your hot water service the most common question asked is what will it cost?
Whilst price is always an important consideration, at Whywait Plumbing believe that there are other equally important factors. This article will help you make an informed decision.
Should The Price of the Replacement Hot Water Service Be The First Consideration?
Besides renovating your home, replacing your hot water service is a major cost. It is often an expense that occurs with very little warning.
Unfortunately, unless you like cold showers, this gives you little time to carefully review available replacement options.
Hot water systems are not all created equal and the choice you make today will be one that lasts for the next ten to fifteen years. With ever-increasing energy costs impacting household budgets, having an efficient and well maintained hot water service has never been more important. A cheap hot water service may cost you a great deal more in ongoing expenses.
With So Many Hot Water Systems On the Market How Do You Know Which One To Choose?
With modern technological advances and the push for energy-efficient heating solutions, it’s no longer a matter of just replacing your hot water system with like for like. So how do you know which hot water service to buy?
Hot water services are available in electric, gas, solar and heat pump models, and all come in a huge range of sizes. Purchasing the right hot water service for your needs is something you should seek advice about from a qualified hot water specialist. With a little help from Whywait’s Hot Water Specialists you will be able to select the system that best suits your situation.
Hot Water Service FAQ’s
Before making any decisions about a hot water service replacement you will need to think about:
- What size is your current hot water service and have you ever run out of hot water with your current hot water system?
- Does your current hot water service operate on an off-peak electricity tariff?
- Are your hot water needs likely to increase, decrease or stay the same over the next five years?
- Do you intend to remain in your current property for at least the next five years?
- What is more important to you the initial up-front installation cost or the ongoing running costs?
- Is the quality of the product and length of warranty a consideration when comparing hot water services?
Once you have answered the above points it will be time to consider the available options.
If you are reading this because you have no hot water and wondering if having no hot water is a plumbing emergency, read on.
Generally speaking if you have time to look a problem up on a website it’s probably not a plumbing emergency (yet) so technically speaking, having no hot water isn’t exactly a plumbing emergency, but still……
Having no hot water is considered a same day guarantee situation for our plumbing business, but this may not be the case for other local plumbing companies.
Even though no hot water usually isn’t an emergency, at our Gold Coast business, Whywait Plumbing, we made the decision many years ago that we don’t consider hot water to be a luxury, so for this reason we offer a same day guarantee for situation where a household is without hot water.
So why haven’t you got hot water?
In our 40 year history at Whywait Plumbing, we have found the most common causes of having no hot water are:
- Faulty element or thermostat (possibly both)
- Relief valve constantly leaking
- Faulty tempering valve
- Off-Peak relay switch failing to activate
- Insufficient sunlight to heat solar hot water
- Demand exceeds capacity
- Leaking hot water service
Hot Water Troubleshooting Checklist
Follow the DIY check list below before calling for help
Locate your hot water service and check the following:
- Check for any leaks at the tank especially around the electrical box. (Do not remove the cover as doing this will expose live wires)
- If the relief valve is leaking activate lever until water runs out in a continuous flow, then return lever to original position and see if the leak stops.
- A faulty tempering valve usually results in tepid water rather than no hot water, you can test this by activating the relief valve and checking if the water in the tank is hotter than the water delivered at the taps.
- If your hot water service is connected to off- peak electricity check with your energy supplier to see if there has been any problems, in your suburb, with transmitting to the relay switch at your home.
- For solar hot water check for foliage blocking sunlight to panels, that panels are clean and if cloudy or wet that the booster switch is on.
Locate the meter board and check the following:
- Check the hot water switch is in the on position.
- Check for a tripped circuit breaker or blown fuse.
Emergency or not, having hot water that is not hot enough, or no hot water, can be unpleasant and inconvenient, however you will be happy to hear in most instances it is a simple fix.

Whywait Plumbing recommends that all adults residing in a household should at a bare minimum know:
- Where the main water isolation valve for the property is located.
- How to turn off the water at the water meter (usually located in a turf box on the property boundary).
- How to turn off the water at the hot water service.
- How to isolate the power to the house at the meter board.
Should an emergency arise where any of the above is required having this prior knowledge will allow the situation to be handled quickly and calmly allowing you to make the situation safe and minimising damage to the property.
Perception is reality and nowhere is this truer for us at Whywait Plumbing than when dealing with the issue of hot water temperature and the possibility of a serious hot water burn.
Everyone has a different perception of how hot they want their hot water whether it is for cleaning or sanitation or personal hygiene use.
Recent research in the United States from the Johns Hopkins Bloomberg School of Public Health, confirms hot water heater temperatures are too high.
In Australia, most manufacturers preset the thermostats for hot water heater temperature at 60-65 degrees. This is dangerously high for a significant proportion of homes, presenting a scald hazard particularly for young children and the elderly. This is because literally hot water burns like fire because:
At 60°C, a serious burn can happen in 1 second
At 55°C, a serious burn would take 10 seconds
At 50°C, a serious burn would happen after 5 minutes
It is estimated a serious hot water burn causes an estimated 1,200 hospital admissions and 50 deaths per year. Young children and elderly adults have thinner skin which burns more quickly putting them at increased risk.
In Queensland, it is the law that hot water delivered to bathrooms used primarily for personal hygiene purposes be regulated by use of a tempering valve or a thermostatic mixing valve that does not exceed 50°C. This is due to the fact that in 1995 the laws were changed requiring tempering valves to be installed on:
all new homes having a hot water system installed
replacement or upgrading of an existing hot water system
or when moving an existing hot water system to a new location on the property
However, homes built before 1995 will frequently still have hot water being delivered at 70°C. It is estimated that 37% of homes still have older electric or gas heaters delivering hot water that presents a scald hazard that will cause a serious hot water burn in one second.
Frequently these homes are rental properties. Many landlords and real estate property managers are unaware that recent litigation has placed a ‘deed of care’ onus on them to ensure the safe delivery of hot water in domestic bathrooms used primarily for personal hygiene purpose.
The installation of a tempering valve is an acceptable solution to hot water scald prevention. Delivering hot water at a consistent temperature is difficult without a tempering valve. This is due to the fact that as a hot water tank is depleted through use then replenished and reheated, the water temperature will not be constant throughout the tank.
Despite a perception by many people, a hot water service thermostat is not designed to provide precise estimates of water temperature. Its purpose is to begin heating when the temperature drops below a set level and turn off when it reaches a set level. Without a tempering valve installed it is almost impossible to assess the exact temperature of hot water delivered from a tap.
The advantage of a tempering valve is that guesswork is eliminated as tempering valves are designed to blend hot and cold water to deliver mixed water at a constant temperature and thus reduce the risk of a serious hot water burn.
Unfortunately for plumbers, property managers, homeowners and property investors hot water has increasingly become a legal minefield with the duty of care provisions.
It is for this reason Whywait Plumbing recommend that you install a tempering valve and maintain it compliantly with annual testing.
During much of the year on the Gold Coast we frequently hear clients ask why do I need to maintain my hot water system there is nothing wrong with it and I’m still getting plenty of hot water. In summer it is easy to forget just how much we depend on our hot water systems for showering, bathing, cooking, washing dishes and washing laundry.
But by April many people suddenly appreciate just how important their hot water system is when it fails to deliver enough or frequently no hot water. Frequently the signs that there is a problem with the hot water system have been there for months and often would have been diagnosed and rectified as part of an annual service. Because hot water systems appear to be complicated many people adopt a head in the sand approach but in reality like most working fixtures in your home they will always benefit immensely from a bit of routine maintenance
In over 37 years of experience we at Whywait Plumbing are well aware that Murphy’s Law applies usually in a spectacular fashion to the failure of a hot water system with most of them failing and leaking late at night usually when it is very cold. In all honesty basic maintenance of your hot water system is fairly simple but vitally it can double the effective lifespan of your hot water system.
To maintain your hot water system the main things you need to allow for are:
- replacing the sacrificial anode every 5 – 7 years
- flushing out all of the minerals and sediment that over time are deposited in the bottom of the storage tank every 3 – 5 years
- have the tempering valve maintained, tested and certified every year
- flush the temperature and pressure relief valve (TPR valve) every 3 – 6 months
- replace the temperature and pressure relief valve (TPR valve) every 3 – 4 years
- replace the expansion control valve (ECV valve) every 3 – 5 years
Apart from flushing the temperature and pressure relief valve (TPR valve) all the other work is legally required to be undertaken by a licensed plumber.
Most concerning from our perspective is the failure to replace the sacrificial anode which is the biggest single cause of premature hot water service failure. Regularly replacing your sacrificial anode will extend the life of your hot water service by ten years or even more. Whywait strongly recommend that you call us to service your hot water system and replace the sacrificial anode every 5 years as the cost of the service is minor compared to the thousands of dollars replacement costs not mentioning the inconvenience.
The one task we recommend you personally undertake is to activate and flush the temperature and pressure relief (TPR) valve. TPR valves continuously work automatically discharging hot water if the temperature or pressure of the water in the storage tank gets too high. Many people fail to understand if your TPR valve is not functioning properly it can potentially cause the tank to explode.
Flushing a TPR valve is relatively easy and straightforward, plus is something you can do yourself, but if the valve is already continually dripping water in all likelihood it needs replacing. To trigger the relief valve and flush it out all you need to do is lift the lever on the front of the valve all the way open and let water discharge from the drain pipe for 5 – 10 seconds then slowly put back the lever in place.
Very simply maintaining your hot water system is an investment not a cost.
