hammer

I have installed the 3 button version of this valve I've put non returns on the hot and cold supplu and a shock arrestor on the main as I've just installed a new combi as well. When I turn off the button s I'm getting quite a bad thud when doing so. I've fitted another shock arrestor to the...

Hi there, For a few years I've had a water hammer in a three storey victorian warehouse conversion. My solution so far was to turn down the water pressure, which works for the annoying sound but my water pressure is not satisfactory. Recently I've decided to try and tackle the problem, and...

hi I’ve recently turned the water back on in the house and suddenly it stopped flowing. It stopped in the kitchen first. After messing about with taps it came back on in the kitchen and has now transferred to the first floor bathroom where it has lost pressure, although improved a bit after...

A bit of background...house was built in 2000. Fitted with screw turn style taps, and washing appliances as new. During our time here, improvements have been made to the house, but these improvements have caused banging issues. The first was the washing machine when stopping water flowing in...

I'm getting banging pipes when a hot or cold tap in the house is turned on full, then turned off. Draining the system of water, then filling back up fixes the problem for 24 hours, then the banging returns. I know dead ends in pipe work, can cause the problem. The heating system in the house...

I live in an old semidetached house and share a mains water supply pipe with my adjoining neighbour. Inexplicably for the past month I have been hearing extreme water hammer every time my neighbour uses her cold water tap/shower/washing machine. I haven't been able to pin down where the hammer...

Hi got a Y plan system in a 3 storey town house and I get a " hammering" sound when the thermostat calls for heat. I've watched and you can see the pipes around the pump (Danfoss UPS2) and 3 way valve (EPH B332PF), vibrate. Further clipping has not helped, in fact made it worse. Both pump and...

Anyone know how to open the as I have a drill bit stuck in it that I cannot get out. This has happened before and I have been able to get it open with my hand and on some occasions with grips but this time It just stalls.

Today I installed some push fit plastic tap tails under the sink. This replaced the previous flexible hose (4 in total joined together by last owner - don't know why). I also installed some push fit appliance taps that will go to a water filter and a dishwasher. Ever since when any tap in the...

I moved into a detached bungalow last June, and last Sept I had a problem with clanging pipes which I only heard in the early hours. This stopped in May for 4 months but returned as soon as it got colder a month ago. I've been woken by loud banging in pipes about 5 to 5.30am. A local plumber...

I'd be grateful for any advice re the following: Background I have a mini water hammer arrestor on the cold feed into my combi boiler, which is situated in the airing cupboard on my house's landing next to the bathroom. Please see the photo. The arrestor was fitted when my old gravity...

Hi All First of all I'll clarify that I am a homeowner and have very little plumbing knowledge, so some / all of my terminology will be very basic / wrong. A few weeks ago my water pipes started 'clanging' when not in use, making the same sound of something shutting off as when I usually turn...

Hello, I had this problem is my bedroom, where there was a rattling in the wall. It turned out it was something to do with water in the pipe, so I turned the water off at the valve, turned all taps on to drain the water out, that problem solved. The other problem now is that I get water hammer...

Had a call back from a customer reported what sounds like water hammer early in the morning and evenings. Trouble is its an Unvented system and also only seems to be happening on the hot. I'm guessing it could be an expansion vessel issue but would be surprised as it's all brand new. My thought...

Good morning, I've just been asked that if someone has a tap which shuts of the water abruptly, such as the cartridge valve taps and water hammer occurs, would fitting a small expansion vessel close to the tap relieve this? To be honest I have no idea but I can find the logic to this question...

Hi Everyone I have a massive water hammer noise coming from "Around" the water meter and main. I'm leaving on the 1st floor of a flat and every time someone opens any tap the pipes are making a terrible noise. The taps seems to be ok, no leaks The toilet filling valve seems to be ok too I've...

I went to look at a job today and there is really bad water hammer in a flat when any hot or cold tap is opened or closed. Its a mains fed system, combi boiler. Its strange though as it will be really bad for 5 mins if using and water, then after that nothing. The guy said it happens randomly...

I had a new combi boiler fitted yesterday switching from conventional boiler. New pipes had to be laid under bedroom floorboards to connect boiler in kitchen up to pipe work in airing cupboard. now after I flush the toilet in the bathroom there is a noise for about 20 mins which I believe is...

I have constant, severe water hammer - loud (~60dB) vibrations in the mains pipe. They were originally started by flushing the toilet, stopping soon after but now they are constant. These vibrations do not stop when the cistern is full, nor do they stop when the valve to the toilet is closed (it...
