Emergency shut off valve are those little valves beneath your sinks and toilets that supply water to the fixtures. They are an important component to your plumbing system as they give you the ability to shut water off to a leaking faucet or drain until repair can be made.
Our corrosive water quality in San Diego County plays havoc with these types of valves and it’s only a matter of time until the stem deteriorates and the valve becomes frozen in whatever position that is in when this occurs. A better valve to use is a “full port” ball valve. Ball valves work by using a lever handle that rotates a ball inside the faucet turn and has no “stem.” A recent innovation is ball valve angle stops and washing machine valves.

The emergency valve is very important and every homeowner should know where the valve is located. If you do not have shut-off valves installed at your fixtures, you should have these valves installed by a certified plumber. You can even acquire shut off Swing Check Valve that have special sensors that will automatically shut off the flow of water if there is a leak which will prevent flooding of the home.
