CMP Inlet Fitting Slip 1-1/2 in., Gunite, White, 25523-100-000

The CMP 25523-100-000 is a white 1-1/2 in. inlet and return wall fitting with a water stop, listed for gunite pools.

What it is

This is the fitting that terminates a return line at the pool wall. In gunite construction the fitting is set into the shell before the shot concrete goes on, and the water stop collar molded onto it blocks water from tracking along the outside of the pipe once the pool is filled. That collar is what separates a gunite fitting from a plain adapter.

Check the connection before you plumb it

The available information describes the connection two different ways. The product name and the short description both call it a 1-1/2 in. slip socket fitting, and a separate line calls it 1-1/2 in. FIP by 1-1/2 in. socket. Both readings are carried here rather than picking one. Match the fitting against the pipe you are connecting to, and confirm whether you need glue or thread sealant, before the fitting goes in.
