Banging/Clunking Pipes

[vards01]

Does anyone know what the best remedy for banging pipes is? Every time the water is turned on or off abruptly the result is a loud banging noise, from around the water meter area. I'm currently in the process of renovating the property so no washing machine or dishwasher installed yet..but will undoubtedly bang like hell when they are. I was thinking of installing a mini rester (small expansion vessel), is this the correct thing to do?

Yep

If your pressure is really high you might benefit from a pressure reducing valve as well

There is very good pressure......it bangs even when the toilet valve closes so is quite frustrating. Is there any particular type of rester or will the £10 one suffice ....screwfix/toolstation type?

How about the position of the rester? Is there a hard and fast rule?

I would get a mini expansion vessel , they sell them in plumbcenter or try euro boiler spares on line, I think they list it as a water hammer arrestor.

Install it just after the stop cock

This is where I'd like to install it, unfortunately the kitchen has now been fitted which gives no access to the stopcock other than to turn on and off.....would this still work if I installed it say just before the boiler c/w feed?

I can't see why that wouldn't work
