CLEAN CHECK 97014 Backwater Valve Slip 4" Pipe

CLEAN CHECK 97014 Backwater Valve

The CLEAN CHECK 97014 is a backwater valve designed for 4-inch drainage systems. It uses a slip socket connection and an ABS body with an ABS stem. The valve meets ASME, IAPMO, IPC, IRC and UPC standards and carries ICC-ES Report PMG-1007. It suits residential and commercial installations requiring code-compliant backflow prevention.

Slip Socket Fit and System Clearance

The valve installs directly into a 4-inch pipe run using a slip socket joint, requiring solvent cement for a permanent seal. Its 9 5/8 inch inlet-to-outlet length determines the straight pipe section needed. The ABS construction eliminates the need for metal corrosion protection in the drainage line. The design keeps the flow path open under normal gravity drainage without adding mechanical restriction.

Sustained Pressure and Temperature Limits

The valve is rated for a maximum water pressure of 75 psi and a maximum fluid temperature of 125 degrees F. Under continuous pressure at the upper limit the ABS body and stem maintain structural integrity without deformation. The sealing mechanism remains effective during prolonged backpressure events typical of sewer surcharge conditions. The listed standards confirm performance for sustained service in approved plumbing systems.
