Pentair 263042 2″ CPVC Straight Check Valve – Pool & Spa Plumbing
The Pentair 263042 is a 2″ straight CPVC check valve engineered to prevent back-flow in pool, spa, and circulation plumbing systems. With a PTFE-coated sealing surface and robust construction, it delivers reliable, maintenance-free shut-off and high flow performance — ideal for protecting pumps, heaters, and other equipment from unwanted reverse flow.
Key Features
- 2″ straight valve body — fits standard 2″ (2½″ outside slip) PVC/CPVC plumbing runs.
- PTFE-coated internal seal — provides a positive, lube-free shut-off that resists sticking and wear.
- Fiberglass-reinforced handle and chemical-resistant CPVC construction — built to withstand pool and spa water chemistry and long-term exposure.
- High-flow straight-through design — minimizes pressure drop and maintains efficient circulation when open.
- Rated for up to 150 psi working pressure — suitable for demanding pool and spa plumbing applications.

When & Why to Use It
Use the 263042 when you need a reliable one-way valve in a pool or spa plumbing circuit — for example, to prevent siphoning back into the pump when the system is off, block reverse flow into heaters, or isolate equipment when multiple lines converge. Its non-lubed, chemical-resistant design makes it especially well-suited for saltwater pools, heaters, or systems using variable chemistry.
Installation & Maintenance Notes
- Install inline with the arrow indicating flow direction pointing toward the return or downstream side.
- Use compatible solvent-weld or slip connections for CPVC/PVC plumbing; ensure proper drying and curing before pressurizing.
- Position the valve where it’s accessible for periodic inspection — check that the internal seal seats cleanly and is free of debris.
- Not typically serviceable — replace the valve if the internal seal or body shows wear, cracking, or leaking.
