Pentair 263042 Check Valve CPVC for Pool Pumps, 2 Port Straight

This worked perfectly. I was losing water level and my hot tub that is attached to my pool. Spring on the previous five was visibly broken. I bought this part, took off the clear plastic part, used it and the internal attached valve to replace the broken one. Holes lined up perfectly with the old part. Completely fixed my problem and hot tub is now holding water at the appropriate level.

I have only had it for a few months, so I cannot comment on how long the metal spring will last (this seems to be the big problem with these valves: corrosion of the springs), however, I can say that the quality seems very good. This valve will add a bit of a restriction to your system, but not nearly as much as other types of check valves.

I needed to replace the check valve in my pool filter piping. This was the best value I found. I only needed the check valve flapper, but buying the entire assembly was a better price and an easy replacement. I simply removed the eight screws from the valve, removed the clear plastic cover and spring-loaded flap and replaced the old one with it. It does not bother me that I now have an extra black plastic housing. I might need it some day.

I just needed the flapper . It fits in the pentair chck valve

Just got two of these, brand new. Filling both of them up with water, each of them leak through the flaps, steadily, with two streams. The rubber cover has tiny holes, which align with the holes on the plastic flap. Is this intentional? Are these supposed to allow a little drainage backwards?

All I needed was the removable clear valve. My pool store wanted $149.99. I got the complete valve assembly for $49 and it's original.

This was all i needed when i bought a new home with an older pool and I woke up to the raised spa water level lowered to the same water level as the pool. I bought the entire Check Valve to my old one leaking after over 10 years of use. I left the original PVC fitting and just took the clear cover and flapper off this one and put it on the old one. Worked perfect for a great price. Saved about $50 over buying it at the pool store.

I had to replace my original pentair check valve housing with this. It was an exact replacement and was nice that it included the check valve too...considering they run almost as these by themselves. I thought about installing it myself but left if for a professional due to the tight plumbing I have.

Exactly what I needed.
