Solenoid Valve
Posted by Phil on March 17, 1999 at 23:22:53:
I want to place a solenoid valve in the water supply line entering my house so that the security system
will turn off the water when we're away. The electrical part is no problem, but I have some plumbing questions.
My water is provided by the city. What should I do about thermal expansion? Is there a concern about
turning off the water supply related to the gas water heater? Aside from the solenoid question,
is there any concern with just turning off the water and doing nothing to the water heater for
up to two weeks. Any advice would be appreciated.
