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.
