CMP 2½" Gunite Pool Water Stop | 25575-250-000

It provides an interface for plaster around a pipe penetration in a gunite pool. CMP’s diagram shows the water stop attached around PVC pipe so plaster can adhere at that interface.

25575-250-000 is the 2½-inch nominal water stop. Match nominal pipe size and CMP’s installation detail; this is not the water stop’s measured outside diameter.

One water stop. Pipe, plaster, adhesive and separate adapter fittings are not included. Manufacturer bag and shipping-box counts describe bulk packaging.

No. It is a passive fitting at the pipe-to-plaster interface; it does not open, close or control the pool’s water level.

Other existing size listings include 1-inch water stop (25574-100-000), 2½-inch water stop (25575-250-000), 3-inch water stop (25575-300-000). The 1½-inch and 2-inch sizes are separate products. Choose the exact pipe size; these sizes are not interchangeable.
