How to stop a water hammer noise from a tap

[@TomBrown-r9v]

Mate. I had a hot tap that was vibrating so loud it almost shook itself apart. Got a domed washer. Instantly sorted. Kudos.

[@dereton33]

Well done Tom.

[@chameleoned]

Wow! This is the fix I needed. We have some beautiful old fixtures on a claw foot tub that came with the house. I’ve rebuilt the hot water side at least 3 times over the last decade trying to quiet it down. Today tried a bevel washer and boom! Quiet tap. Amazing how long I’ve been looking and this seems to be the only vid mentioning this fix. Fantastic work! Thank you

[@dereton33]

You're welcome!

[@rickgauthier402]

So easy - 15 seconds to fix an issue that has been a problem for 3 months. Thank you

[@dereton33]

No problem Rick.

[@frederickting1947]

Thank you so much. I fixed 2 annoying taps that 'pounded' when turned on. For months we tolerated them. Almost called a plumber in which could have costed us hundreds. But for less than $3 for 2 dome shaped washers we resolved the problems.

[@dereton33]

That`s great.

Oh my freak days. I'm so annoyed. I had this noise of water hammering for months from the bathroom sink. Was driving me crazy. Watched a couple of this geezers video and then came to this. Read one of the comments and it was staring me in the face....water pressure! So turn down main stop tap pressure and realised that pressure too much upstairs, adjusted the cold/hat stop taps on thr bathroom tap and BOOM problem solved. Thank you so much. I can't express how grateful I am to you.

[@dereton33]

No problem Azzam. Pleased you sorted it.

[@thomasc1457]

Thanks a lot mate, this helped me fix my hot water tap problem that caused that bloody water hammer banging sound

[@dereton33]

+Ozzy Doop . No problem.

[@johnl275]

Thanks very much for the tip. I have the washer vibrating problem on a washing machine conversion tap which has a water inlet tube in the centre of the washer rather than a standard removable valve and washer, so I removed the flat washer and replaced it with a conical washer intended for a flexible hose nut. So far, it is working and has stopped the hammering when the tap was partially opened. 😁😁😁

[@dereton33]

Glad it helped John.

[@quyenvoi]

Thank you for a great video. I have a question here please. My house, the water pressure is ok when I open only 1 source of water(kitchen faucet, washroom faucet); however, the water pressure is very very low and almost no water upstairs if I open 2 sources of water(1 upstairs and 1 downstairs faucets or flush the toilet and open 1 faucet). Any idea of why this problem? Thank you!

[@dereton33]

Not enough mains pressure. Contact your local water authority to see if it can be increased.

[@michaelroberts5098]

Great video thanks, I screwed a dome washer on the tap but there's not enough thread to put the nut on (as in the video). Do I need to put the nut on our will it be fine without it? Thank again

[@dereton33]

Be fine without it.

[@sarveshpavale3930]

thank you Sir,... Please Help me, i have a query...i can't find hammering, i mean where exactly it is in the line, whether gate valve got eroded or all taps' washers are gone ? Guide me sir

[@dereton33]

If you get the hammering when you open a particular tap then just replace that tap washer. If you get it when you run a tap or flush the loo, then it is the roof tank ballcock.

[@deepakdani1798]

@@dereton33 Hammering sound in flush system is due to air trapped in the line Ball cock has nothing to do with hammering sound

[@deaneprox]

Great video thank you! I live in a small block of flats and whenever some one uses shared mains, there is loud water hammer. Mine does the same and can hear the bang coming from the actual stop cock rather than tap. Building is for the 60's and likely still have original stopcock, so could a replacement washed in each stop the banging, or would new stopcocks be recommend? Is there anything else that could be the cause please? Water pressure is 3.5 bar, so unlikely this would be the cause would it?

[@dereton33]

That would definitely be it, water pressure is too high, see if you can get it down to about 2 bar. Try turning the main stopcock right off, then back on, just a half of turn.

[@deaneprox]

Thank you for your reply. I like you thought it would be related to high pressure, but I had Thames Water out who took measurement and said 3.5 bar isn't so high. I could certainly adjust my stopcock, but getting all 5 other neighbours to do this might not be suitable as of course lower pressure will mean weaker showers.

[@dereton33]

Yes the problem with flats.

[@paulplavecsky1671]

How it’s made

[@chris76xx]

Hi when I flush the toilet or run the shower there’s a noise and my kitchen tap shakes and runs even though it’s in the off position . Any ideas what the problem is ? Thanks

[@ishakumar2336]

I have the same issue right now

[@BlckDuck]

Thank you for the information. I have a single handle faucet. It is brand new and was just installed. It was not doing this before and the plumber doesn't want to take ownership and fix it. The stops were also changed out. Can you give me some suggestions? It looks like I am going to have to fix this myself.

[@dereton33]

First thing, turn the pressure down at the stopcock.

[@BlckDuck]

+dereton33 I tried turning the pressure down. I thought it worked, but no. I am still getting the noise. I turned down both hot and cold water to no avail.

[@dereton33]

If there is a small ballafix valve on the pipe work or the fleixi connector to the tap, try turning that down, if you do not have one then consider fitting one yourself.

[@brendanhoffmann8402]

Good luck Jason.

[@MrPauljameswilson]

This worked a treat for me. Thanks very much for the tip.

[@dereton33]

You're welcome!

[@videos40058]

dude i have this problem myself with one ceramic tap. The hammer noise happens because of the moving watter and sudden top will create a huge spike in pressure and putting at risk all the installation that has bad joints. My Tap is a monoblock dual mixer and it only happens when you shut the water off . With your one you cannot do it fast anyway but with a up and down motion you get that alot. What is the solution to that? I assume we need to install a expansion vessel to absorb the spike of pressure on that line. Is that a good solution?

[@dereton33]

Yes that is the best solution a pressure vessel fitted on the cold supply line to the tap.

[@jontaylor4511]

mine disappeared when i put a softer rubber washer in, didn't wear well though compared to the nylon. might try this.

[@twitterfacetube]

Hello, can you help me out. We recently had a plumber replace the float valve on the tank in the attic as it was worn out and leaking. Since then I've noticed, particulary at night when it's quiet, that when you flush the toilet and the cistern is filling up, you can hear a vibration coming from what sounds like the tank in the attic. This morning I could hear the noise from the kitchen and when I touched the cold tap, which was off, I could feel it vibrating. When I turned it on slightly the noise and vibration stopped. Any idea where the problem lies ?, Thank you

[@dereton33]

The water flow is too high, try turning down the flow rate at the main stopcock.

[@ravenmaster6364]

Great video and a big help! I really need to have a go at our kitchen mixer tap. The bathroom cold water tap also sets this noise off in our house and you have to run downstairs and faff with the kitchen one till it stops 🙈 🤣, let's hope it's just the washer !

[@dereton33]

Fingers crossed.

[@mikede2331]

Haha exactly same as we but I get screeming toilet aswell that likea to keep me awake, i been meaning to have a look for a years or 2 now and change my tap but I'll change the washer

Our garden tap makes a monumentally loud noise which resonates through the pipes in my upstairs bedroom. The noise is insane so I hope this works, we shall see. Not sure where to turn the water off but I will find out. Thx for the advice.

[@dereton33]

Good luck with it.

[@Jizzlewobbwtfcus]

@@dereton33 Had a look. There are multiple vales attached to the water pipes and I have no clue which one is for the water faucet directly so I'm going to leave it for now and wait until the next time a plumber comes to the house to do a yearly inspection. I don't want to end up creating a 'Some Mothers Do 'Ave 'em' scenario hehe :D

[@richardfrommatrix06]

@@dereton33 Thanks for your reply. I think your videos are excellent by the way! Apart from matching size, I'm guessing that it can potentially be swapped over to a standard gland so that I can fit the dome washer?

[@dereton33]

[@LexCameron]

One upstairs tap has water hammer so I wonder if this will help. I've got a problem with both old upstairs 1960s taps with a cross handle (like the one you're holding here, both HOT taps), in that they both gradually over time switch the water on themselves. After a few weeks they'll be dripping, after a few months there may be a small flow. What's happening? Is it the tap, or something to do with the condenser boiler?

[@dereton33]

A pressure problem.

[@LexCameron]

@@dereton33 OK, Thanks. It's not happening on the cold taps, so do you think it suggests it's something to do with the hot water boiler? - we also have the Water Hammer on one of those taps.

[@CollosalTrollge]

hi thats what i have never understood is that the one you have doesnt have a little nut on the end, mine does. I find also over tmie the washer actually gets so warped or unshaped thats it gets a bigger hole in the center which then allows the washer to slip off the tap stem thing. really taps and pain, i dont really understand why they are built like they are.

[@dereton33]

Nor do I.

[@dereton33]

Just try turning the main stopcock flow down to a slower rate.

[@jonnygti]

My dad had this problem but with his outside tap, it would start the hammer noise after turning it a couple of times, but if you keep turning it even when its hammering away it would stop, then when you turn it back off it would do the same, just seemed to be at a certain point, and if your inside the house it sounds like the whole house is vibrating! not sure if he ever got that fixed, might have to show him this video. cheers

[@dereton33]

Replace the roof tank ball clock.

[@chilixi]

I have a sink that has one handle that you turn to either side for hot or cold. What do I do for that?

[@dereton33]

Remove the handle and undo the body of the tap.

[@johnbull5394]

Another tip learned from experience is that the nut holding tap washers in place often falls apart when you try to undo it, and then you'll often find there's then nothing to physically hold the washer in place. Using a socket or ring spanner instead of an adjustable to remove said nut makes this breakage less likely to happen.

[@easyTaff]

Turning a stop cock down reduces flow but does not reduce the pressure. You need a pressure relieve valve (PRV) to do that.

[@kay_que]

I've been up all night trying to stop this horrible vibration coming from my hot water bath tap. My case is different because not only does the noise come when the tap is on and upon closing but it comes on randomly by itself which is scary and agitating. Can you please explain why it comes on by itself with the tap off? Thank you

[@dereton33]

If the tap is low pressure feed from a roof tank. then when the tap is used the valve in the loft has to fill to replace the water you have used. So just replace the ballcock in the tank and job sorted. If you are on a combi boiler then the tap washer wants replacing and the water pressure turned down. Some times just reducing the flow of pressure by turning down the main stopcock can fix it.

[@preetinayee6296]

Replace the valve or the valve washer.

[@SWhite-hp5xq]

These rubber dome washers are not a long term solution. They wear out very quickly. Better solutions available, for home gamers, this includes anti hammer washers, in-line control valve, inline hammer arrestors. Recutting the valve seat and adding a new neoprene washer can fix sometimes the issue to. All parts readily available at big hardware stores.

[@dereton33]

They all cost a lot more than a 5 p tap washer.
