Pentair 263042Z Check Valve Rebuild Kit for 2" & 2.5" CPVC Valves

Restore your pool or spa plumbing to peak performance with the genuine OEM Pentair 263042Z Check Valve Rebuild Kit. Over time, check valve flappers and seals can wear out, causing unwanted backflow and loss of pump prime. Instead of cutting out your plumbing to replace the entire valve body, this convenient rebuild kit allows you to easily swap out the internal components in minutes. Designed specifically for Pentair 2-inch and 2.5-inch CPVC Check Valves, this kit ensures a perfect, leak-free fit.

🚩 PRO TIP: Installation & Maintenance

Replace this kit at the first sign of backflow or leaking. To ensure the clear lid creates an airtight seal and to prevent the O-ring from pinching, apply a thin coat of Aladdin Magic Lube to the large lid O-ring before tightening the screws. This is a quick DIY repair that takes under 30 minutes and prevents pump cavitation.
