water hammer

I'm experiencing a water hammer when my hot water comes on, following on from the heating. My hot water is on a timer, to come on twice a day to fill a hot water tank. If I have my heating on in between, then when the hot water come on there is a nasty, loud water hammer. The hot water /...

Hi lads just had a new boiler fitted and they put a water hammer arrester under the boiler i started getting water hammer " ive never had this before" so i called them back and they cured the problem by taking the water hammer arrester off and said it was that which was causing the water hammer...

This may sound odd but I wonder if it rings any bells. On recent threads to solve a water hammer problem, I fitted a hammer arrestor on the attic feed pipe. Turns out it was not needed as it was a float valve in the tank. All seemed to be well until I turned off the water to the attic and...

Hi All, recently, when I turn the bath hot tap on, just slightly, a very loud shuddering, like a pneumatic drill, can be heard from the pipes/floor/tap? When I turn the tap on fully, it stops. Is this water hammer? It doesn't happen all the time, just every so often. But it is so loud and...

Loud hammer noise when one particular hot tap is turned on. Clears quickly when tap is fully opened, or when a hot tap in the next room is opened. Sounds like the hammering is at or near the tap itself. Last night I was awoken by a hammer which sounded like it wasn't going to stop. I found the...
