Installed in the circuit between the pump outlet and downstream components such as the filter or heater, it helps maintain consistent pressure and protects equipment from backflow when the pump stops. This compact valve fits standard 1.5\" spa piping with slip-fit connections, making it a straightforward upgrade or replacement in existing spa systems.\u003c\/p\u003e \u003ch2\u003e\u003cstrong\u003eConstruction, Compatibility and Integration\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eConstructed from durable PVC with an EPDM gasket, the V20-342 is built to withstand chlorinated spa water and the temperature range typical of residential spa systems.
