Product details

The Pentair 263042 is a straight bodied CPVC check valve in black for pool and spa plumbing. It passes water one direction and blocks it the other.

What it is for

When the pump shuts off, gravity pulls water back through the plumbing. A check valve stops that. It keeps the pump holding prime so it restarts without an airlock, and it keeps output from a chlorinator or chemical feeder from drifting backward toward equipment that should not see it.

CPVC, not PVC

CPVC is rated for higher water temperature than standard PVC. That makes it the material of choice on the discharge side of a heater, where returning water can be well above the comfort range of plain white pipe.

A note on size

The source information for this valve is not consistent about size. The listing title describes it as a 2 inch valve, while the product description describes it as a 2 inch to 2-1/2 inch valve. Both readings are given above. Measure the pipe you are plumbing into and confirm the connection before ordering.

Questions and answers

What people ask about this product, answered by our pool techs.

What size pipe does this valve take?
The source is not consistent. The listing title calls it a 2 inch valve and the product description calls it a 2 inch to 2-1/2 inch valve. Measure your pipe and confirm the fitting before you order.
Why CPVC instead of PVC?
CPVC is rated for higher water temperature, so it holds up better on the hot side of a heater than standard PVC.
What does a check valve do on a pool?
It lets water pass one way and blocks it the other, so the pump and plumbing hold prime when the system shuts off and chemicals do not drift back toward the pump.
Is this a genuine Pentair part?
Yes. It is Pentair part number 263042.
