Why do my pipes knock when water is on?
A: The knocking sounds are what’s known as water hammer, caused when water flowing in pipes suddenly shuts off and vibrates with enough force to cause the pipes to knock against wood framing. Manufacturers now make inexpensive, easy-to-install water hammer arresters where these appliances connect to the water system.
What would suddenly cause water hammer?
Water hammer can occur when an open valve suddenly closes, causing the water to slam into it, or when a pump suddenly shuts down and the flow reverses direction back to the pump.
Where are water hammer arrestors installed?
The best places are either close to the pump, isolation or check valve that is originating the hammer, or at more distant points where the pipe changes direction, for example at the top of a pump riser.
Can water hammer burst pipes?
The Water Hammer Problem The effect of the shockwaves can damage the pipes and knock them loose, and also damage taps, faucets, and appliances. Enough force from water hammer can even cause pipes to burst. If you hear rattling sounds along with the water hammer, it likely means you have pipes coming loose.

How do you get air out of water pipes in your house?
Leave the water running for about two minutes. Start from the lowest faucet in the house to the highest faucet. This allows the water pressure of the system to force all of the air from the pipes and out through the faucets. Once the water is running from all outlets normally, turn them off.
Can a check valve cause water hammer?
Water hammer is a common issue with traditional check valves. A traditional swing check valve requires gravity and flow reversal to fully close. When this happens, the flap on the valve slams shut, abruptly stopping the flow, and allowing the effects of water hammer to ensue.
