- For the 263034 body Listed as the internal assembly for the 263034 7.5 inch P-style slide valve body.
- Complete internals Supplied as a piston assembly rather than as loose seals to be built up.

Product details
CMP 25831-130-100 is the piston assembly for a slide valve, supplied as the internal assembly for the 263034 7.5 inch P-style slide valve body.
What goes wrong with a slide valve
A slide valve seals with a piston that travels inside the body. The body is rigid PVC and lasts, but the seals on the piston take the wear, and over time they let water past even with the handle fully down. That is what an owner notices first: a valve that is closed but still passing water to the drain or to the return.
Rebuild rather than replace
Because the assembly comes out of the top of the body, the valve does not have to come out of the plumbing. That turns a cut and glue job into a parts swap. While the internals are out, look down the bore for scoring, since a damaged bore will wear a new piston assembly quickly.
Confirm the fit
P-style slide valve bodies are made in more than one size. This assembly is listed for the 263034 7.5 inch body, so check the size and the body number against what is in your plumbing before you order.
