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?
