HOW TO FIX WATER HAMMER OR RESONANCE CAUSING LOUD NOISE
Read below for information on how to fix:
1. WATER HAMMER: A loud bang in your pipes after a fill valve shuts off. Water hammer can be caused by worn or damaged faucet washers as well as heavy build up of minerals and rust inside shut off valves (located on the walls of your home).
2. RESONANCE: The rapid banging or “Jack Hammering” sound in a pipe during the fill process, during the flush.
1. WATER HAMMER:
Follow these steps to try and resolve water hammer:
Shut off water supply to the house at the main.
Open all the cold water faucets, start with the highest faucet (2nd or 3rd floor) and work to your lowest faucet (first or basement floor).
Flush all the toilets in the home.
Let water drain from open faucets. Wait approximately 20 to 30 minutes.
Turn on water supply to the house at the main.
Wait 5 to 10 minutes to let faucets regain a strong stream and flow water.
Close all the cold-water faucets starting with the lowest faucet (first or basement floor) and to the highest faucet (2nd or 3rd floor).
Toilets will automatically refill.
Once all faucets are closed and toilets filled, flush toilets to check for water hammer.
If this does not resolve your issue, try these tips:
Reduce flow from shut off valves (wall or floor valves).
If you are not using a regulated fill valve (a toilet valve that regulates flow into the toilet tank), try replacing the toilet fill valve with a Fluidmaster PerforMAX® Fill Valve.
If reduction of shut off valve does not resolve issue, Fluidmaster recommends calling a plumbing professional to help resolve the issue |
