The photo below shows my pool return that is divided between a Caretaker in-floor cleaning system and wall jets. The amount of flow to each can be controlled with a Jandy valve. If I close the flow to the wall jets, I still get significant flow through those wall jets. I am assuming that flow is coming through the pressure relief valve, even though the pressure never reads more than 15 psi. It was my impression that the pressure relief valve isn't supposed to be open unless pressures exceed 30 psi. Would if be safe to assume that my pressure relief valve is stuck open and should be replaced? I've never been impressed with the strength of flow coming out of my floor cleaning jets.
