Zoeller Zoller-zco 30-0042 Quiet Check Valve 2 in Pvc

Product Description

The ZOELLER zoller-zco 30-0042 is a full-port quiet check valve designed to prevent backflow in sump pump and drain pump discharge lines. Built with a PVC body and PVC trim, this valve accepts 2-inch solvent weld connections and is rated for up to 50 psi and 130 degrees F. The rubber softgoods internals allow quiet operation by dampening the closing action of the flapper, reducing water hammer noise common in standard swing-check designs. Plumbers and pump installers use this valve when a low-noise solution is required in residential basement drainage systems.

This check valve is suited for residential and light-commercial sump pit discharge lines, basement drain pump systems, and other water-service piping where backflow prevention is required. Its flexible installation orientation — vertical or horizontal — makes it adaptable to a range of discharge line configurations. The solvent weld socket end style creates a permanent, leak-resistant connection to standard 2-inch PVC schedule pipe and fittings.

Key Features

• Full-port design allows unrestricted flow through the 2-inch discharge line
• Quiet check mechanism reduces water hammer and closing noise compared to standard swing-check valves
• Installs in vertical or horizontal orientation for flexible discharge line routing
• Solvent weld socket ends bond directly to standard 2-inch PVC pipe
• Rated to 50 psi and 130 degrees F for typical residential sump and drain pump service
• White PVC body with rubber softgoods for corrosion resistance in wet environments

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 2-inch PVC sump pump and drain pump discharge piping in residential and light-commercial applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Disconnect power to the pump before servicing any portion of the discharge line. Apply solvent cement per the fitting and cement manufacturer instructions, and allow full cure time before restoring flow. Verify the flow arrow marked on the valve body is oriented in the correct direction of discharge before bonding.
