It works, so straightforward and effective, many thanks dereton33 for guiding on eliminating loud vibrating sounds from the inlet pipe to the apartment water tank ('hot press'). I turned the brass stop cock right back as you indicated, almost off (lots of pressure where we are), and the noise is gone, sparing the need for expensive treatment.

Interesting video Al. Another cause can be the outside tap when it is turned on and plugged into a hose connected to a garden sprayer connector or timer. It seems to create a hammer noise. I was a bit confused until I realised the tap was on, and turning it off cleared the problem.

I had a water arrestor fitted after I started to experience water hammer when turning taps off and all it did was make the bang happen when the water was turned on instead! I then had a pressure reducing valve fitted and the problem went completely. It's great because you can adjust the pressure just like you adjust the temperature on a radiator thermostat. Apparently, water hammer is becoming more of a problem due to more people working from home which means the water companies have had to increase the pressure to cope with demand.

My rural cottage just changed from pumped well water to a mains connection, and the changes included a real plumber installing a float valve in the upstairs tank. I have no complaint about his work, but within a few days I started having severe water hammer to the point where I feared the pipework would spring a leak. The solution (found online) turned out to be ridiculously easy: tie an upright empty 300ml yogurt tub onto the float arm, with the top of the tub just below the surface of the water. This damped out the "chatter" as the float valve is close to shutting off, and it completely cured the problem. I was expected it not to work at all, but it was cheap (literally nothing) to try so what the hey. I absolutely did not expect a complete cure! I had previously tried closing the valve a tadge, but that didn't seem to help.

@@amberalert...agirlwithapho9597did you sort it out? I have same problem 😢

[@daveface69]

Although some of this may sort of work, there's a few problems here. First you should not rely on throttling isolation valves to reduce pressure - this will cause cavitation and cause the valve to fail prematurely. If throttling solves the problem, then what you need is a flow restrictor or PRV as you mention at the end. Second at 01:39, unclipped pipes do not 'cause' water hammer, they will just make you aware of it. Water hammer is CAUSED by the momentum of water being suddenly stopped, and the resulting pressure wave - rattling pipes are a secondary effect of the pressure wave. Clipping the pipes in place won't change the fact it's happening (and damaging your pipes / fittings)

[@dereton33]

Thanks Dave.

Thank you, this was immensely useful!

I live in a flat and I can hear water gushing when my downstairs neighbours is using her taps, also bangs violently when they stop it’s driving me crazy what can be done

[@dereton33]

The water pressure is too high. See if your neighbour could turn her flow rate down by turning the main stopcock off and then back on by about half a turn or so.

[@Caddman96]

Thank you very helpful

[@dereton33]

You're welcome!

[@Familysykes]

I get it when I use washer bath toilet and all taps it made my boiler fire up didn't realise untill I got a £175 gas bill for 1 month.. I was advised I need a shock arrester at stop tap The bang is under the toilet

[@dereton33]

O well least you have it sorted now.

[@MegaMan-bs3oy]

My moms house in town didn't syart doing this intil someone remodeled a house next door now it does this everytime the toilet is flushed or the washer is turned on they redid the pipes over there and apparently messed the pressure up

[@dereton33]

This is indeed a pressure problem.

[@Rojata19]

I've tried reducing the pressure, I've also drained the pipes and refilled them from the top down, I've identified the pipe that's banging and secured it down and I still have the banging noise..... Its coming from the mains stopcock, hidden away at the back of a cupboard and the pipes going upstairs have been boxed in and plastered over 🤦‍♂️ What would you suggest?

[@dereton33]

Try turning down the flow rate of the outside main stopcock.

[@Rojata19]

​@@dereton33 hi, I've tried turning down the flow but still getting a banging noise, it happens more when the washing machine is in use so I'm thinking of installing an arrestor....do you think that'd work?

[@monikaa3188]

Did you fixed it?

No one with visit due to the covid-19. Much appreciated.. 🙂

[@dereton33]

Try reducing your water flow by turning down the main stopcock Emma.

[@ehtashamtaj2594]

Get the hammer noise mostly when the washing machine is going, it's so annoying and also get it when I open the kitchen tap on full.

[@dereton33]

Try turning the main stopcock down.

No problem Matt.

when i drain my bath i hear a dripping sound when it’s draining is that normal

[@dereton33]

Yes, it`s ok.

[@candlelove0952]

This hammer 🔨 sound in the water pipes is so loyd and bangs the whole house when I start the washer machine!

[@dereton33]

Try turning the flow rate down on the main stopcock.

[@Mickeyj26]

try these they screw directly into the back of the washing machine take the pipe off the inlet put this in and then put the pipe in the back of the unit job done www.ebay.co.uk/itm/LG-Washing-Machine-or-Dish-Washer-Stop-Noisy-Pipes-Water-Hammer-Thumping-Pipes/151659279378?hash=item234f98f412:g:4dUAAOSwYlRZKTHn Get one from Oatey though if you have a big overhang at the back of your machine because you will need a longer shaft for clearance How to do it and at the end shows that it works we only need one though in the uk because we dont use a hot water supply kzbin.info/www/bejne/naHFm2Sno7epa7c

[@BJT_89]

@@Mickeyj26 installed these and it’s still the same banging, any thoughts?

[@Mickeyj26]

@@BJT_89 did you install these to the washing machine (dont install them to the pipework you want them where the pull of the solenoid valve is) and have you got one for each inlet (if your washing machine has hot and cold) if you have and it sounds the same you can maybe send them back and ask for another set as they may be faulty. If you do that and things are still the same maybe the banging is the pull on the pipes because some pipework isnt secured to the wall across its length well enough and the inertia yanking at the pipes are making the clang back and forth. Other than that t cold be your water pressure is very high so maybe only 3/4 open the taps that are connected to the washing machine instead of fully opening them.....see if that helps.

[@BJT_89]

@@Mickeyj26 I installed them on the wall side, not at the washer. I found conflicting information, but the more I research, sounds like washer side is the way to go. I’ll switch them around and hope that fixes it.

Thanks. Job's a good'un 👍

My pipes have been having issues, first whistling and now water hammer, lmfao

[@whatfreedom7]

I know the feeling. My shower stopped mixing temps. Thought I had that fixed and two days later and my pipes sound like a jack hammer.

[@pumbar]

Have you got a baked potato plugged into the wall socket behind you there?

[@dereton33]

Ha ha it does look like it. It is actually a salt lamp.

Funny enough I have already got one on them, done about 2 years ago.

I cannot stand it since I’ve had my leaking pipe repaired it keeps banging constantly

Try tuning the stopcock down to reduce the flow rate.

Thing is no water is running that I know of

Turn the main stopcock down to a lower flow rate.
