Common questions

Shutoff Valve Replacement Questions



When should I replace a shutoff valve?

Replace a shutoff if it is stuck, leaking, corroded, hard to reach, or unreliable during fixture repairs or emergencies.



What does a PRV do?

A pressure reducing valve helps control incoming water pressure so fixtures, heaters, valves, and pipes are not stressed by excessive pressure.



Can high pressure cause leaks?

High pressure can contribute to stress on plumbing parts and may make weak points fail sooner.



Should I handle shutoffs before installing Moen Flo?

Often yes. A clean, accessible plumbing setup helps smart shutoff devices work properly and makes future service easier.
