Product details

The CMP 25830-400-000 is a Hydro Seal check valve in black CPVC with a 2 in. socket on one end and a 2.5 in. spigot on the other. It carries a 2 lb spring, is rated to 50 psi, and is NSF certified. It is a serviceable valve, so the internals can be reached without cutting it out of the line.

Where it goes

A check valve keeps water from running backward when the pump shuts off. On a pool pad that means holding prime on a suction line, keeping a heater or chlorinator from draining back, or isolating a solar loop. The dual size body fits directly into 2 in. pipe or a 2.5 in. fitting, which covers most residential equipment pads.

Built for pool water

The body is CPVC and corrosion resistant, in black. The 2 lb spring closes the valve as flow stops without adding much restriction while the pump is running. Because the valve is serviceable, a worn flapper or spring is a quick fix in place rather than a replumb.

Questions and answers

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

What do 2 in. S and 2.5 in. SPGT mean?
One end is a 2 in. socket, which 2 in. pipe glues into. The other end is a 2.5 in. spigot, which glues into a 2.5 in. socket fitting. Both ends can be used, so it fits either pipe size.
Is the valve serviceable?
Yes. It can be opened in place to inspect or replace the internals, so a stuck or worn flapper does not mean cutting the valve out of the plumbing.
How strong is the spring?
It is a 2 lb spring. That is light enough not to add noticeable restriction on a pool pump loop while still closing the valve when flow stops.
What is the pressure rating?
50 psi. It is CPVC, corrosion resistant and NSF certified.
