Pasco C29-126 Sump Pump Check Valve

Product Description

The PASCO C29-126 is a sump pump check valve designed to prevent backflow in residential and light-commercial sump pump discharge lines. A check valve in this application stops pumped water from draining back into the sump pit when the pump shuts off, reducing short-cycling and protecting the pump motor from unnecessary wear. This valve is installed inline on the discharge pipe above the pump outlet. Plumbers and sump pump service technicians are the primary installers for this fitting.

The C29-126 is used in sump pump systems where a reliable one-way flow barrier is required on the vertical or near-vertical discharge run. It is suited for new installations and direct replacement of failed or aging check valves in basement drainage and crawl space dewatering setups. The valve weighs 1.35 pounds, making it straightforward to handle and position during installation.

Key Features

• One-way flow design prevents backflow into the sump pit when the pump stops
• Reduces pump short-cycling by maintaining column pressure in the discharge line
• Lightweight at 1.35 pounds for easy single-technician installation
• Direct replacement form factor for standard sump pump discharge applications

Compatibility

Designed as an OEM-style replacement check valve for residential and light-commercial sump pump discharge installations. No specific model compatibility data was provided; verify pipe diameter and connection type against the existing discharge line before installation.

Installation Notes

Installation is typically performed by a licensed plumber or experienced service technician. Disconnect power to the sump pump before beginning any work on the discharge line. The valve must be oriented with the flow arrow pointing in the direction of discharge; installing it backwards will block pump operation. Local plumbing codes, including applicable IPC requirements, should be consulted for approved materials and installation methods.
