water pressure regulator
Posted by Robert on June 21, 19100 at 15:31:35:
I understand what a water pressure regulator does, but I do not understand how it does it. Is "water pressure regulator" actually a misnomer for water "flow restrictor?" A restrictor would not protect the system from overpressure in a static state (the water is turned off in the house). The regulator I recently purchased appears to small to have moving parts. I just want to understand how it works. Thanks.
