Ashland Water Group PCV125 Spring Loaded Check Valve

Product Description

The ASHLAND WATER GROUP PCV125 is a 1.25-inch plastic spring loaded check valve designed to allow one-directional flow and prevent backflow in fluid piping systems. The spring-loaded mechanism closes automatically when flow stops or reverses, protecting pumps, lines, and equipment from reverse flow damage. Constructed from plastic, the PCV125 is well-suited for applications where corrosion resistance and light weight are priorities. It is typically installed by licensed plumbers and pipefitters in residential and light commercial water systems.

The PCV125 is used in water supply, irrigation, pool and spa circulation, and general plumbing applications where backflow prevention is required at a 1.25-inch pipe connection. Its plastic construction makes it appropriate for freshwater service where chemical compatibility with the plastic material has been verified. This valve fits inline into the piping run and requires no external actuation — the internal spring handles all valve operation automatically.

Key Features

• 1.25-inch connection size fits standard 1-1/4 inch pipe fittings
• Spring loaded mechanism provides automatic closure on flow reversal
• Plastic body construction offers corrosion resistance for freshwater and compatible fluid service
• Compact inline design requires no external controls or actuators
• Lightweight at 2.5 pounds, simplifying handling and installation

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 1.25-inch plastic piping systems in residential and light commercial plumbing and water circulation applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve system pressure fully before cutting into any existing line. Verify flow direction markings on the valve body before installing — check valves are directional and will not function correctly if installed in reverse. Solvent-weld, threaded, or slip connections should be made per the fitting manufacturer instructions and allowed to cure before restoring pressure.
