|In response to Re: water pressure regulator|
If it were just a flow restrictor, then closing the control valve would do the same thing. It has a diaphragm inside it and a spring to close the diaphragm. The less pressure on the spring, the lower the pressure that the diaphragm will allow downstream. Tightening the adjuster screw increases the system pressure.
: 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.
