This Check Valve Flapper Replacement is a corrosion-resistant aftermarket repair part compatible with Jandy-style pool and spa check valves. It replaces the worn or torn internal flapper (equivalent to part 7056) that seals against backflow — restoring proper one-way flow without replacing the entire valve body.

Frequently Asked Questions
Which valves does this flapper fit?
It's designed as a replacement for the Jandy-style check valve flapper (equivalent to 7056) and fits common Jandy check valves including the 7235, 7236, 7305, 7511, and 7512. Confirm your valve model before ordering.
Is this a genuine Jandy part?
No — this is a quality aftermarket replacement compatible with Jandy-style check valves. It's designed to match the fit and function of the original flapper at a lower cost.
What does the flapper do?
It's the hinged internal seal that allows water to flow one direction and closes to stop backflow. When it tears, stiffens, or warps, the valve stops holding prime or lets water flow backward.
How do I know my flapper needs replacing?
Common signs are loss of prime, water draining back when the pump shuts off, or a check valve that no longer holds pressure. Often the flapper is the only worn part — the valve body is still fine.
Does it include the O-ring?
Yes — the replacement includes the O-ring needed to reseal the valve when you reassemble it.
Do I need to replace the whole valve?
Usually not. If the valve body and unions are in good shape, replacing just the flapper restores full function for a fraction of the cost.
Frequently asked questions
How do I identify the right replacement valve?
Valves are specified by port size, port count, connection type - slip, threaded or union - and body material. Measure the pipe outside diameter rather than guessing at nominal size, since PVC sizing does not match the physical measurement.
What should I check before ordering this valve?
Confirm the dimensions and connection sizes against the part you are replacing. If the specification above does not answer your question, send us your equipment model and serial number and we will check it before you buy.
Why is my valve leaking or hard to turn?
Stiff operation and weeping around the stem usually mean dried-out or chemically degraded seals. Many valve bodies can be rebuilt with a service kit rather than replaced outright, which avoids cutting into the plumbing.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Jandy equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
Can I automate this valve?
Diverter valves in this style commonly accept a valve actuator so an automation system can switch them, but the actuator and its mounting hardware are separate items. Confirm the valve body is a type the actuator is rated to drive before ordering.
Is there a warranty on this valve?
It carries the standard Jandy manufacturer warranty. The terms are set by Jandy, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
