How to stop a water hammer noise from a tap 

Thanks so much, 65 years old and just learned something new. Fixed the hammer!

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.

Blimey, it's Quint from Jaws!

volume too low. Also can you show water hammer noise due to washer malfuction.. Are you sure it is bang bang noise.

Thank you!!

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

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

Yet again a great video Al! Your advice on plumbing problems is priceless - Thanks!

Thanks. My sink just started hammering like crazy while washing the dishes. So I’m going to get some dome washers from the hardware store and see what happens. Thanks a lot

Awesome, worked like a charm! The donation is on the way!!

Hi, just wanted to say a massive thanks for the video, after trying many different things for months this cured our problem and was a 5 minute fix and very cheap. Fully appreciated thank you 👍

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

This is the first thing i could find that actually answered my questions. Great video. Awesome tip.

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

Love the shirt 😉👍🏻

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?

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

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!

I had Severn Trent out and they put a new stopcock outside number 19 which as the man said it between for 19 18 17 16 since they put the stopcock in my hot water tap in the kitchen vibrating I had a engineer out from Severn Trent and he said it my Valle and go for a new double tap low pressure one I got a combo boiler please please help.

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

My kitchen mixer has started doing this but it's a quarter turn ceramic.

good info.... your nails are interesting though, DAMN!!!

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

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

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?

He always talking about mixers

You are top man! Thank you.

ThNks so much for this advice…. Hot bath tap has been driving me mad…. Toilet flushing… kitchen tap… upstairs washing machine (I’m in a marionette) everything sets it off!

Thanks for this. I can't even begin to explain the annoying sound coming from my dishwashers tap at night when I run it 💀

Thank you, I replaced the washer and fixed, Thank you Thank you!

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

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.

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.

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

I have this problem when running cold but it is from a single handle kitchen tap that controls both hot and cold. Planning on replacing ghe whole tap to upgrade the look lf the kitchen sink.

seriously watched 8, maybe 10, seemingly promising vids that got me nuttin but older....until this one came along. Now my hammering days is in the past, where they truly belong. God bless you olde mate....cos the rest a these ytube commentary experts sure wont >..

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. 😁😁😁

You are adorable - shirt, accent, hat. Gorgeous canvas too. Can you come fix my faucet please? Good day mate

Great video! Solved the problem! Thanks!👍

Toilet flush did hammering that to me sounded like the plumbing was trying to rip itself apart!

Great video Thank you

Hugh Hefner???

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

Worked like a charm! for $2.50! Dome tap washer

Shout out for my childhood home, Bude, in the background

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

Awesome video solve the problem, thanks a lot and that sweet smile is adorable.

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

Another very helpful video, Al! I like the panoramic picture on the wall, too!

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?

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.

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.

Thank you.

Thanks, but how does this work on a quarter turn tap? Mechanism doesn't seem like it would fit?

Very experienced, thumb up mate!

What size should the dome washer be for a hot/cold mixer tap in kitchen sink? Thanks

You can create a major problem using dome washers.

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.

Thank you for being simple and effeminate... Your video helped the best . Thanks.

Thank you

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 !

Thanks Derek. I’ll look into changing the washer. 👍

Nice simple informative video.

By the way I don’t have a roof tank .

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.

top geezer!

Thanks mate.

Geezer

Thanks!

Damn dude is great with advice but he needs to cut his prehistoric witch lookin Nails Lol 🧙🏻‍♀️ But all n all great tips Thanks man

It appears that you have a bit of clubbing in your thumbs and fingers. This may be indicative of heart disease. Please have your heart checked out.

Dude... those finger nails!! Can i send you a nail clipper?

I almost lost my breakfast because of your nails...

Hi, thank you for the video, I have the rattling problem just on the hot tap water after I changed to a new one. If I use dome washer, is it the same thing? Thank you again

I get 1 bang when I turn on either the kitchen taps or the bathroom sink or bath taps. What would that be?

Thanks so much for this video, saved me a huge plumbers bill! I changed the washer and instantly the problem was fixed. Super easy!

Great Vid Al ...your rocking that shirt mate.! how are you getting on with the Maplin weather station?
