1 1/2"-2" 180 Degree Check Valve
Product Overview
CPVC straight-through check valve designed to protect pump prime and prevent chemical backflow.
The Jandy Pro Series 7235 180-degree check valve prevents reverse water flow and water hammer across filtration and heating loops. Fabricated from temperature-resistant CPVC, the body plumbs directly to 1.5-inch PVC pipe on the internal socket or 2-inch pipe over the outer collar. A clear inspection lid allows fast diagnostic checks of the flapper and stainless steel spring without breaking pipe joints.

When To Use This
Pro Tip
In pools with calcium hardness above 400 ppm, mineral scale can crust along the flapper hinge; inspect the gasket annually and clean it with diluted vinegar. When installing, always use CPVC-to-PVC transition cement and ensure excess glue does not drip down onto the hinge pin.
Common Questions & Instructions
What symptoms indicate my Jandy 7235 check valve needs replacement?
Loss of pump prime within 5 to 10 minutes of equipment shutdown typically signals flapper seal failure. Hairline fractures around the 8-screw lid or persistent backflow into chlorinators also indicate it is time to rebuild or replace the valve.
What pipe dimensions and operating limits does this check valve support?
The dual-dimension ports fit 1.5-inch pipe internally and 2-inch fittings externally. It is rated for a maximum operating pressure of 50 PSI and supports flow rates up to 170 GPM in standard residential configurations.
Can I rebuild the flapper without cutting the valve out of my plumbing?
Yes. Removing the 8 stainless steel machine screws releases the clear cover, flapper plate, and spring mechanism. A complete rebuild takes under 15 minutes without disturbing the glued CPVC body.
