Wondering if anyone can explain how a PRV (pressure reducing valve) works? I have a water pressure gauge connected to my hose bib right after the PRV. It measures 75psi. When I open a faucet inside my house, the pressure is dropping to 60psi. Is this normal, or not? Is the PRV supposed to maintain the 75psi when faucet is open? Thanks! Jen
