What is a water surge or water hammer?
At Whywait Plumbing, we understand that a water surge or water hammer can be frustrating and potentially damaging for homeowners. That’s why we’re here to explain the problem in simple terms and offer solutions for preventing and resolving it.
Water hammer or water surge is a common issue in any system that utilises pipework, valves, pumps, and other equipment to control water flow or other liquids throughout a building.
One of the most common causes of a water surge or water hammer is the rapid closing of a valve. When a valve is closed quickly, water hits a dead end, sharp bend, or any other situation that creates a high-pressure shockwave to travel through the pipework, causing a loud banging noise and increased pressure. This can damage pipes, fittings, and appliances and cause leaks.
Another common cause of water surge is a problem with your pressure pump system. If your pump is malfunctioning, it can create a surge of pressure that can cause the same issues as a rapidly closed valve.
The effects of water hammer can range from a loud knocking or banging noise in the pipes to more severe issues such as broken pipework. However, the risks posed by water surge are particularly significant in high-rise buildings.
High-rise buildings are susceptible to water surge
Most high-rise buildings have at least one riser that runs from the basement to the top floor and connects to smaller distribution pipework on each floor. Suppose a pump stops operating, for example, due to a power cut or a fault in the system. In that case, the water pressure in the building gradually declines as outlets are opened, and the remaining water in the system is drained under gravity.
This can create a vacuum in the pipework, depending on whether there are non-return valves or pressure-reducing valves installed in other parts of the water pipe reticulation system. When the power is restored, and the pump begins to operate again, it restores system pressure to pre-set levels. However, if the unit is not designed, installed and maintained correctly and does not have a comprehensive “soft fill mode”, the water hammer or water surge will be almost unavoidable.
In the worst-case scenario, pressurised water is pushed into a vacuum, causing the water to accelerate beyond expected design velocities. This can be due to multiple pumps running or pumps that are designed as “standby”. This results in a hydraulic shock to the pipework that can be beyond the operating pressure of the system, potentially causing weak pipework or connections to burst, resulting in flooding and expensive water damage within the building.
Not only is this expensive to repair, it means downtime to the building’s water supply. It is also a severe health and safety risk to those occupying the building during the burst.
To avoid these issues, it’s essential to take the necessary precautions. One solution is to ensure that you have a booster set with a surge protection feature, so when the pumps are powered back up, they are limited to one pump and gradually increase their pressure to avoid ramping up too quickly. In addition, an AWSPV valve or an Air and Water Protection Valve can be installed at the top of each riser. This device not only avoids vacuum being created, but it also forces air through the “anti-surge” orifice when the system is filling, allowing for the deceleration of the incoming water supply, thanks to the resistance created by rising air pressure in the AWSPV valve.
This softens the potential pressure spike when the AWSPV valve finally closes. The AWSPV valve design ensures effective de-aeration under all pipeline flow and operating conditions via one of three discharge orifices. Once the system is full and free of air, the valve seals and must be piped to a drain or safe area to ensure any leaks are discharged to a visible position. This ensures that everything is visible without causing further water damage.
In conclusion, a water hammer or water surge is a common issue in any system that utilises pipework, valves, pumps, and other equipment to control water flow throughout a building. High-rise buildings are particularly at risk due to the potential for a vacuum to be created when the water pressure is restored, which can cause a surge in water pressure and potentially cause damage to the pipework or connections. By taking the necessary precautions, such as ensuring a booster set with a surge protection feature and installing an Air and Water Protection Valve, you can avoid these issues and ensure the safety and reliability of your building’s water supply.
Proactive prevention you should implement
To prevent water surge, it is crucial to have your plumbing system regularly inspected and maintained by a professional plumber. This can help identify any potential issues before they become a problem.
Even in your traditional home, installing a water hammer arrestor, a device that absorbs the shock wave created by a rapidly closed valve, can help prevent water surge or water hammer from occurring.

Protect your home from burst flexible hoses with auto flood stop isolation valves
One of the most common causes of home water damage is burst flexible hoses. These hoses are often used for taps, toilets, washing machines, dishwashers, and fridges.
While they are convenient, they can also be a source of severe problems if they burst. That’s why it’s essential to have an auto flood stop isolation valve installed on any flexible hose in your home. These valves will automatically shut off the water flow if a hose bursts, helping to prevent extensive damage.
What are auto flood stop isolation valves, and how do they work
Auto flood stop isolation valves are specifically designed to prevent flooding in homes. These isolation valves can detect and arrest water flow when flexible hoses burst, thus preventing water spillage into the adjacent rooms and flooding houses.
The valve works by acting as a check for water should the flexible hose start leaking and detects excessive water usage, triggering an automatic shut-off of the isolation valve so that the house remains safe from water damage. With these auto flood stop isolation valves, homeowners can rest easy knowing their home is protected even when flexible hoses burst.
Burst flexible hoses are a prime reason for installing auto flood stop isolation valves in your home
Installing water auto shut-off valves in your home can be a great way to protect your property from water damage caused by burst flexible hoses. Not only does water damage from these sources cause immediate destruction in the area it leaks, but it can also cause long-term issues as water works its way into walls, floors, and other unseen areas.
Installing water auto shut-off valves helps you avoid expensive repairs that can come with water damage and give you peace of mind knowing that the auto shut-off valve will turn off the water before a disaster quickly. Preventative measures such as installing water auto shut-off valves should be essential to caring for your property and should not be ignored.
How to install them in your home’s plumbing system
Installing auto flood stop isolation valves in your home plumbing system can seem intimidating, but it can be straightforward with the right expertise and assistance. At Whywait Plumbing, we are experienced in installing auto flood stop isolation valves to ensure a secure and proper installation. In addition, we will be able to run through the whole process with you and answer any questions.
Overall, auto flood stop isolation valves provide significant protection for your home plumbing system, making installation worth it in the long run.
The benefits of having auto flood stop isolation valves in your home
Having auto flood-stop isolation valves in your home is a great way to lower your insurance premiums and provide protection from water damage caused by burst flexible hoses. This type of valve automatically shuts off the water supply when it detects excessive water usage, reducing the risk of severe water damage to your home.
This extra layer of defence can give you peace of mind that you are doing all you can to protect your home and lower the chance of incurring expensive rectification costs associated with water damage. Additionally, installing them could mean lower insurance premiums since using such a device shows that you have put measures in place to protect your home from potential disaster.
Why you need auto flood stop isolation valves installed now
Auto flood stop isolation valves are a reliable and effective means of avoiding burst flexible hoses and stopping potentially disastrous leaking in your home. Such valves will detect any burst flexible hoses or fittings immediately. The containment of hot and cold water up to the isolation valve can be stopped within seconds.
This is possible with the help of a built-in detector in the valve that constantly monitors water pressure and flow rate while also ensuring that taps and appliances have the correct amount of pressure running through them. Thus, auto flood stop isolation valves provide homeowners with peace of mind and utmost safety in dealing with burst flexible hoses without incurring too much cost or worries about burst flexible hoses flooding the house.
Although auto flood stop isolation valves are not required to be installed, they offer increased protection for your family and valuables. Imagine the damage that could occur with a bathroom vanity mixer tap hot water flexible hose bursting while you are on holiday. In that case, the valve will automatically shut off the hot water flow into the mixer, limiting the amount of damage that can occur. Installation is relatively simple and can be done by licensed plumbing professionals at Whywait Plumbing.
Have you considered adding auto flood stop isolation valves to your home?

What causes Copper Pipes to get Electrolysis?
Copper pipes are a popular choice for plumbing because they are durable and resistant to corrosion. However, over time, copper pipes can develop a problem called electrolysis. This occurs when electrical currents pass through the pipes, causing them to corrode and weaken. If left unchecked, electrolysis can lead to leaks and even pipe failures. In this blog post, we will explain what electrolysis is and how to prevent it from causing copper pipe leaks.
Electrolysis is a chemical reaction that occurs when electricity is passed through a liquid or metal. In the case of copper pipes, the electrical current can come from a variety of sources, such as nearby electricity wires or stray currents from appliances and lights in ceilings. When the current passes through the copper pipes, it causes a reaction between the copper and the water in the pipes, which can weaken and corrode the pipes over time, causing copper pipe leaks.
Common signs of electrolysis in copper pipes are the blue-green discolouration on the pipes. This is created by the formation of copper oxide over time and is a byproduct of the electrolysis reaction. This electrolysis can cause pinholes and leaks in the copper pipes.
Increasingly the most common cause of electrolysis that we are finding is an electrical fault in the earthing of the copper pipes. This is especially true with properties that have been renovated. Unfortunately, locating earthing issues is complex, and we need to use an electrician to confirm or eliminate earth leakage as the cause. Other electrolysis causes can be due to dissimilar metals, such as galvanised, steel, brass and copper pipes, coming into contact with each other.
How do you know if your copper pipe has electrolysis?
Often the problem is not found until you have copper pipe leaks. For example, your copper pipe may have turned green and shown pitting. Once the leaking section of the copper pipe is removed, you will observe that the inside is no longer smooth but has internal corrosion. A close inspection will reveal a crater appearance with pitted holes starting to form.
Once a copper pipe leaks due to electrolysis, it is essential to locate the cause. The replacement copper pipe quickly becomes infected if the reason is not found and removed.
To prevent electrolysis in copper pipes, it’s crucial to identify and eliminate the source of the electrical current. This will involve working with an electrician to check for stray currents or power line interference. In addition, it’s vital to use corrosion inhibitors in the water supply to help protect the pipes.
Another way to prevent electrolysis is to use a cathodic protection system. This unique device is installed on the pipe to provide a negative charge, which neutralises the positive charge caused by the electrical current and prevents the corrosion of the pipes.
In addition to these preventative measures, it’s also important to regularly inspect and maintain your copper pipes. This includes checking for signs of discolouration or leaks and ensuring that the copper pipes are appropriately insulated to reduce the risk of electrolysis.
In conclusion, electrolysis is a problem that can occur in copper pipes and can cause significant damage. However, by understanding the causes of electrolysis and taking steps to prevent it, you can help ensure that your copper pipes remain in good condition for many years. For example, suppose you suspect that your copper pipe leaks are ongoing and may be experiencing electrolysis. In that case, you need to contact the qualified plumbers at Whywait Plumbing to diagnose and repair the problem as soon as possible.

Water damage insurance claims are an issue we deal with every week. We are continually called upon to deal with insurance companies or assessors on behalf of clients when they have sustained water damage to their homes.
With COVID-19 lockdowns keeping a large proportion of Australians at home, research from QBE Insurance indicates water damage insurance claims remain at high levels.
New research from QBE Insurance revealed that 77% of people who experienced water damage were home at the time of the incident, unravelling misconceptions that flooding mainly occurs when the house is unoccupied.
The QBE Insurance research statistics reveal that:
- 77% of claimants impacted by water damage were at home for the water damage incident.
- Burst pipes, blocked pipes, damaged roofs and old plumbing are the main water damage culprits.
According to the research, internal water damage is typical, with 58% of survey respondents having experienced internal water damage themselves or know someone who has, or both.
This coincides with QBE claims data, which found water damage incidents account for almost a quarter (24%) of all home insurance claims. Water damage insurance claims are one of QBE’s most regular home insurance claims. An average claim is $5,000, and more severe water damage claims commonly reaching over half a million dollars.
“Preparedness and prevention are key to limiting the potential damage caused by internal water damage,” says Arron Mann, General Manager, Short Tail Claims at QBE.
“Water damage can happen whether a household member is at home or not being home more often, as many of us are right now, can increase the pressure on our plumbing and risk to our homes. However, this kind of damage can also be sudden and severe regardless of whether you’re home or not, which is why prevention and knowing what to do when something goes awry are so valuable.”
Despite 53% of research respondents saying their first response to water damage would be turning off the water main, 1 in 5 Australians (21%) don’t know where their water main is, and worryingly, 1 in 5 (18%) also don’t know how to turn it off.
The QBE research also revealed that almost 30% of Australians don’t know what home maintenance tasks can prevent water damage in their homes, with 16% not knowing that home maintenance can prevent it in the first place. Cost is also a factor, with 21% not undertaking any home maintenance because it’s too expensive, while 8% say they don’t have the time.
“Sometimes, the difference between no damage and severe damage can be in how quickly a householder responds. Yet concerningly, many people are unaware that much of this damage – and the stress and cost that comes with it – is often preventable,” says Arron Mann.
The best way to avoid water damage insurance claims is by regular maintenance from Whywait Plumbing. Now this will not prevent every possible water leak scenario from happening, but it will demonstrate to the insurance company that you have been undertaking regular maintenance if claim difficulties occur.
At Whywait Plumbing, we see instances every day of water damage that has occurred through the failure to maintain your home regularly. That is why we recommend all our clients to become a Service Partner and enjoy the VIP benefits of having a Service Partner Plan to maintain your most valuable asset, your home, proactively.

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 Gold Coast water is set every year as part of the budget process with the detailed current water pricing for 2021-22 available from Gold Coast Water.
What are the costs of 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:
| Residential Charges |
Cost |
| Sewerage access charge per quarter |
$181.03
|
| Water access charge per quarter |
$53.02
|
| Total Access Charges per Quarter |
$234.05
|
The usage charges per kilolitre as measured by your water meter are made up of council charges and Queensland Government charges as below:
| Residential Charges |
Cost |
|

|
$1.117
|
| Queensland Government water per kilolitre |
$3.231
|
| Total Cost of Water per Kilolitre |
$4.348
|
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.
Our experience is that the average water use of 451 litres or 0.451kL per property shown on Gold Coast water bills is not an accurate guide to your water use.
Most homes with more than one occupant will use 1-2 kL every day. However, 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 and alert you to a potential water leak.
The actual cost of water dripping from a tap
What will cause your water usage charges to blow out is having leaking water that you are unaware of. 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 practical purpose.
If we translate the litres wasted to the cost of water, then the numbers become real very quickly.

The actual cost of a leaking underground water main
You can visually see a dripping tap or running toilet, 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 accurate average for any leaking water main supply pipe because it depends on the type of break in the pipe, what the pipe size is and what the incoming water pressure is.
Recently we had a client with a small leak where we have 24/7 electronic water monitoring installed that is leaking on average of 45 litres per hour, so we use that as a basis for what leaking water main will cost on a Gold Coast water bill.
| Cost of a leaking underground water main at 45 litres per hour |

A water leak at 45 litres per minute is only a relatively small leak in larger pipes. It is unlikely to show up as bubbling at 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 an easier task to locate a leak. However, unless you have an AquaTrip installed or use our 24/7 water monitoring service, you will still pay for a large amount of lost water before you become aware of the water leak.
If you think you have a water leak contact us because every litre that you lose is costing you $0.004348 for residential properties or $0.008909 for businesses on your Gold Coast water bill. If you naively feel that is inconsequential, we have just rectified a leak for a commercial business client in a 50mm underground polypipe water main that was leaking 106 kL every day, which is 106000 litres every 24 hours. This leak cost $944.354 every day.
