Banging pipes when showering

Question

Our water pipes are making a banging noise when we use the shower. Just when we turn it off. Is this a serious problem and how do we stop it?

Grant · Answer

It may be the ball valve in tank which would not be expensive to change

Michael · Answer

Try opening your stopcock fully failing that it sounds like you have some old pipe work that’s capped off maybe running into loft . This could be full of air causing water hammer

Elliott · Answer

Hi, this could be cause be either pipes not being clipped correctly,  or could be water hammer which can be stopped by having a shock arrester fitted.

Catalin Iulian · Answer

the mixer tap must be changed because the water does not come continuously

Steve · Answer

Hi the banging noise is not a major problem it is pressure building up in your pipes you probably have one of your taps in your property that the valves are stuck with limescale and not releasing properly causing a buildup of pressure this can be easily fixed

Patrick · Answer

Showers are best having their own direct feed. Especially if you don’t want temperature fluctuations when a tap is turned on or a toilet flushed while you are in the shower. The banging may be from the mains supply feed. Try to locate the banging pipe and secure it. Check the stopcock in the loft water tank if you have one.

Hi, yes it can lead to a elbow   or joint coming loose and causing a potentiall leak, to resolve it, you need to clip the pipes to a wall or floor

The pipes been fitted too close without any clips between them.

Have a shock arrestor fitted on your cold main somewhere in the house. Usually under the boiler is a good place to put it, it will stop the water hammer and also protect any plastic parts in your boiler from pin holing from the pressure build up

Stuart · Answer

It’s what you call water hammer. It’s caused when a valve closes quickly. If you turn the shower off slowly, it won’t happen. It’s not a particularly serious problem although if it gets really bad, potentially it could cause a fitting on the cold system to fail which would have obvious results. The way to solve it would be to fit a shock arrester on the cold main. If you have a combi boiler, the shock arrester would be fitted on the cold supply just below the boiler.
