Water Heater Pipes Vibrating

If you have air in a pipe caused by a recent repair or another issue you will have to deal with the shaking and sputtering pipes for a short time until the air is forced out.

Water heater pipes vibrating.

I installed a new water heater about 6 months ago and have had a consistent water hammering mild that occurs every 10 minutes. I ve lived in this house for 18 years and this is the first time this has happened. Ignoring the vibration in your faucet s hot water supply pipe can lead to serious problems with the pipe since the vibration could be the early warning sign of major problems. Just leave your faucets on until the water flow returns to normal.

Now if a cpvc line was routed through a hole or area that is too tight you ll hear a rubbing clicking knocking noise anytime hot water runs through that pipe. Another indication the heater needs maintenance is a rumbling sound produced by sediments being stirred by the water flow inside the tank. If maintenance does not cure the problem the noises may be something as simple as the expansion and contraction of the main steel tank or expansion tank during normal operation. Once the pipes are all drained turn the water main back on.

Some homes use cpvc chlorinated polyvinyl chloride as their hot water supply pipes i e. Sometimes a water hammer can occur when a pipe mounting strap is loose. You can see a helpful diagram of this phenomenon here. There are two heating elements an upper and a lower and it s not uncommon for the upper heating element to vibrate and hum when cold water flows into the tank and circulates around the system.

Use a deliming mixture to clean the tank and drain the water heater. A water hammer is what happens when the water inside the pipes hits the valve when you close the faucet. These straps consist of metal plumber s tape or the vinyl coated nail in hooks and hangers that attach pipes to framing. The water supply pipes in your house s plumbing may make noises or vibrate for a number of reasons including water hammer or broken straps.

Turning off the cold water faucet at the sink also causes a vibration. If a vibrating pipe seems to be behind a wall if you need a new water pressure regulator or if you d like to install slow shutting valves to avoid water hammer issues call your trusted plumber who ll take care of the problem efficiently and well. Water hammers can be very loud and very disturbing but you ll only hear a water hammer after you ve turned off the faucet. My water pipes started vibrating about a month ago.

It doesn t happen all the time. Pipes can vibrate and sputter or spit violently making lots of noise if there is air trapped in them. In four of the baths when the toilet is flushed the water cutoff causes the pipes to vibrate very loudly somewhere in the wall or ceiling.
