Water hammer, whistling and chattering of pipes is annoying and can be costly.
Water hammer is the thump in the piping heard when faucets or valves are turned off abruptly.
It can usually be eliminated by the installation of an air chamber or short length of pipe in the wall where each supply pipe enters a plumbing fixture.
Proper clipping of the pipes during installation is another preventative method.
Shock arrestors should be installed on the main line near the meter or as close as possible to the cause of the noise.
How is the condition outside of the house, either along the water main or in a neighbouring house.
Skillful detective work by an experienced master plumber is necessary to ferret out the source of the trouble and to plan corrective methods.
Water hammer should be fixed immediately.
The noise is only an audible symptom of what is going on in the piping.
The piping is being worn and damaged by the multitude of shock waves.
The result will be leaks in piping, tanks or fixtures unless the condition is corrected.
Chattering in the piping may be caused by loose pipes, by pipes rubbing against a metal projection, by worn faucet washers or looseness of other inside parts. Poor clipping of pipes and fixtures.
Whistling is caused by the speed of water flowing through piping which is usually too small or has not been deburred properly by the plumber.
A pressure reducing valve will help as will a general checkup and straightening out of the plumbing system.
Whistling is most common at bends and tees in the pipe. This is where the fitting is connected to the unburred pipe or where the incorrect join may cause friction.
Thank you.
