How To Stop Water Hammer

Article Summary: 

Water hammer is a banging noise or unusual vibrations caused by sudden stoppage of water flow in pipes. This noise can lead to pipe damage, leaks, and costly repairs. One of the ways to stop water hammer is to install an air chamber, which acts as a cushion for water to rebound when it changes direction suddenly. Another solution is to adjust the water pressure reduction valve or stabilize loose water supply lines. If these solutions do not work, a water hammer arrestor can be installed to control the effects of water hammer. To remove water hammer after flushing a toilet, homeowners should turn off the main water supply to the house, flush all the toilets, and check for any debris trapped inside the fill valve and water supply hose. If necessary, the fill valve may need to be replaced due to wear and tear.
