Zoeller dj-545 Abs Pvc Stainless Steel Check Valve

Product Description

The ZOELLER dj-545 is a check valve engineered to prevent the backflow of water in sump pump systems. Constructed with an ABS body and PVC and stainless steel components, this valve is built to handle the corrosive, wet conditions common in sump and drainage installations. At 6.44 inches tall and 2.25 inches in both width and length, it is a compact unit suited to tight sump pit configurations. Vertical installation is recommended for proper operation. Licensed plumbers and pump service technicians handle the typical installation.

This check valve is designed for use in residential and light commercial sump systems where backflow prevention is required on the discharge line. Vertical installation keeps the internal sealing mechanism operating correctly and helps prevent water hammer on pump shutoff. The combination of ABS body construction with PVC and stainless steel materials makes this valve well suited to continuous contact with water and the minor chemical exposure common in sump pit environments.
