Zoeller Zoller-zco 30-0048 2 Inch Pvc Check Valve

Product Description

The ZOELLER zoller-zco 30-0048 is a full-port quiet check valve designed for backflow prevention in residential sump pump and drain pump discharge lines. Built from a PVC body with PVC trim and rubber softgoods, this valve handles water service up to 50 psi and 130 degrees F. The full-port design minimizes flow restriction, and the quiet operation reduces water hammer noise during pump cycling. At 10.5 inches in length and sized for 2-inch nominal pipe, it installs via solvent weld connection in either vertical or horizontal orientation, giving installers flexibility in tight mechanical spaces.

This check valve is suited for residential basement sump pump systems and drain pump discharge applications where backflow prevention is required in the discharge line. The solvent weld end connection integrates directly into standard 2-inch PVC Schedule 40 or Schedule 80 piping. Its dual-orientation capability makes it practical for installations where pipe routing does not allow a strictly vertical riser. Plumbers and sump pump installers working in residential crawlspace or basement environments will find this valve a straightforward fit in common discharge configurations.

Key Features

• Full-port design reduces flow restriction through the discharge line
• Quiet operation minimizes water hammer during pump start and stop cycles
• Rated to 50 psi and 130 degrees F for standard water service
• Installs in vertical or horizontal orientation for flexible pipe routing
• Solvent weld connection for secure, leak-resistant integration with PVC pipe
• PVC body and trim with rubber softgoods for corrosion resistance in wet environments

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 2-inch nominal PVC discharge lines in residential sump pump and drain pump systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified pump technician in accordance with applicable local plumbing codes. Disconnect and lock out power to the pump before cutting into the discharge line or handling any existing valve. Solvent weld connections require proper PVC primer and cement applied per manufacturer instructions, and joints must be allowed to cure fully before restoring system pressure. Confirm flow-direction arrow on the valve body is oriented correctly relative to pump discharge flow before cementing.
