Water Pressure problem
My home is two stories, with a basement, in the Northeast. Public
water enters the basement, then there is a ball valve, regulator, meter, dual check valve, and another ball valve. Over the last several weeks (since it has gotten cooler), most mornings there is no water at the second story of the house. I then go to the first floor and try the kitchen faucet. If there is good flow in the kitchen, it will usually then charge the system up to the second floor. If there is no water on the first floor, I have to go to the basement and close and open the downstream ball valve. This will then charge the whole house. Closing and opening the upstream ball valve in the basement does not charge the system. I figure my problem is either the regulator or the dual check valve. Anyone have an idea how to remedy this, and what is a dual check valve? |

Anyone have an idea how to remedy this, and what is a dual check valve? http://www.crd.bc.ca/water/crossconn...checkvalve.htm The valve is there to prevent water in the house lines from backing up into the street Main. I bet the dual check diaphragm is sticking under pressure. Since you have a PRV and a check, the water heater must have an expansion tank. Does yours? Without one, system pressure can go above normal. Another possible is that the street Main pressure suddenly drops overnight, causing the check to jam. Jim |

Water Pressure problem
presuming your water line is not freezing, phone and ask the water
company to come and replace the meter for this specific problem. when they come, be there to ask them your questions. this will eliminate the meter as a possible problem. if the problem continues, replace the next items one at a time. todd wrote: My home is two stories, with a basement, in the Northeast.
