Pressure Limiting Valve

What Is a known as Water Hammer?

When you shut a tap quickly, the water moving through the pipe has to stop instantly. All that momentum has to go somewhere, so it slams into the closed valve and sends a shockwave back through your pipework. That is the bang you hear.

It often sounds like it is coming from a different room than the tap you just turned off, because the shockwave travels the whole system. That is normal, and it is not a clue about where the problem is.

Left alone, water hammer loosens fittings, fatigues pipe joints and shortens the life of tapware and appliances. It is one of the more common causes of a burst flexi hose, which is a much more expensive problem than a noise.

Water Hammer Causes

What Causes Water Hammer in
Adelaide Homes

Five things account for nearly everything we get called to:

High mains pressure

The most common cause by a wide margin in Adelaide, and the one most often missed. Covered properly below.

Outdoor irrigation valve assembly lying on grass next to a sprinkler line.

Loose or unsecured pipes

Pipes that were never clipped properly, or where the clips have worked loose over decades, move when the shockwave hits and knock against framing or masonry.

Fast-closing solenoid valves

Fast-closing solenoid valves

Washing machines and dishwashers shut off almost instantly by design. If your banging happens during an appliance cycle rather than when you touch a tap, this is usually why.

Causes of Backflow in Adelaide Homes

Worn tap washers and valves

A failing washer lets the valve close erratically instead of cleanly, which makes the shock worse.

A failed or missing arrestor

Where an arrestor was fitted, they do wear out and stop absorbing shock.

Will came to my house to look at the roof stormwater drainage to the street. I only recently moved into this second-hand home and they had all sorts of DIY-looking downpipes, some of which went nowhere. He thoroughly investigated the issue, reassured me and came up with a good plan to fix it in a cost effective manner. On top of being professional he was also very personable and I had full confidence in his advice.

Fantastic experience. William was prompt friendly and polite. He got down to business straight away and didnโ€™t waste time. He laid it all out and provided his honest opinion. He has the experience we needed to do the job and also showed us the inside of our pipes with the camera.

Thank you for the service and excellent help. Came out for our emergency blockage and checked out the house. Diagnosed the fault and supported us with SA water to resolve the issue.

Amazing work will recommend and call again!!!

I contacted Will late on a Sunday afternoon with blocked drains and not only did he respond quickly, but he made time to come first thing Monday morning. Will was professional and lovely to deal with. He went above and beyond contacting SA Water on our behalf, and followed up with me throughout the day to see how the job was progressing. As it turned out, the issue was on SA Water's side, but without Will's expertise and help I would never have known and possibly spent a lot of money paying for work that I wasn't liable for. I would highly recommend Wills Plumbing Adelaide.

William was excellent in his communication before, during and after his visit. He was clear with his explanation of our water hammer and pressure issues and transparent with his recommendations for remedies and cost. He was also friendly and understanding as I managed small children and our dog while he worked. Our water hammer issue appears to be fixed - he has asked us to keep him posted if we experience any further issues. Ongoing care - tick! We really felt well looked after and couldnโ€™t recommend William highly enough. Thanks!

Will was a pleasure to work with. His communication was clear and responsive from start to finish. He went the extra mile by offering practical DIY ideas that could save us money, rather than immediately opting for a call out. Overall, Will's approachable attitude and willingness to help made a great impression. Weโ€™ll definitely reach out to him first for any future plumbing needs.

FAQs

Water Hammer Related Questions, Answered By Our Adelaide Plumbers

It is worth fixing. On its own, when the noise is harmless, the repeated shock loosens fittings, fatigues joints and wears out tapware. It is a common contributor to burst flexi hoses, which cause serious water damage.

The water stops moving instantly, and the momentum turns into a pressure shockwave that travels back through your pipework. In Adelaide,the usual underlying cause is mains pressure above the 500 kPa limit, which makes every shock harder than it should be.

Washing machines and dishwashers use solenoid valves that shut almost instantly. If the banging only happens during an appliance cycle, an arrestor at that connection is often the answer.

Sometimes. An arrestor absorbs shock at one point, which works well when a single appliance is the culprit. If your mains pressure is too high, an arrestor treats the symptom and the pressure keeps damaging everything else. That is why we test pressure first.

You can check the simple things. Make sure your mains stop tap is fully open, and buy a pressure gauge for around twenty dollars to take a reading off an outside tap. Anything involving cutting into your water supply must legally be done by a licensed plumber in South Australia.

Same-day service is available across the Adelaide metro for most jobs. Call before mid-morning for the best chance of a same-day slot.
