Val-Pak V20-342 Spa Check Valve - 1.5 in

Prevent Backflow and Protect Your Spa Equipment with a 1.5-Inch Inline Check Valve

The Val-Pak V20-342 Spa Check Valve is a 1.5-inch inline one-way valve designed to prevent reverse flow in spa plumbing. 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.

Construction, Compatibility and Integration

Constructed 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. The 1.5" slip-fit connections simplify inline installation and align with common spa piping layouts. Its compact form factor ensures it integrates cleanly into tight plumbing runs without added bulk or complexity, while preserving the correct flow direction indicated by molded arrows.
