Rectorseal CV01.5IN Sump Pump Check Valve 1.5 in Abs

Product Description

The RECTORSEAL CV01.5IN is a 1.5-inch in-line check valve designed for sump pump discharge lines in residential and light commercial drainage applications. Built from sonic-welded ABS thermoplastic, this valve features a full-flow internal passage and a rubber flapper that seats firmly to create a positive seal, preventing backflow when the pump cycles off. The unit ships with rubber coupling sleeves and stainless steel clamps, allowing direct connection to either PVC or ABS discharge pipe without additional fittings. Licensed plumbers and experienced service techs handle installation as part of a standard sump pit setup or retrofit.

This valve is suited for in-line installation on vertical or near-vertical sump pump discharge runs in residential basements, crawlspaces, and light commercial sumps. The full-flow design minimizes head pressure loss across the valve, which helps preserve pump performance. The included coupling hardware makes it a field-ready solution when connecting to existing PVC or ABS pipe stacks without special adapters.

Key Features

• Sonic-welded ABS thermoplastic body for durable, leak-resistant construction
• Full-flow internal design reduces restriction and maintains pump efficiency
• Rubber flapper provides a positive seal to prevent discharge backflow
• Compatible with both PVC and ABS discharge pipe via included coupling sleeves
• Stainless steel clamps included for secure, corrosion-resistant connections

Compatibility

Designed as an OEM-style replacement or new-install check valve for 1.5-inch PVC or ABS sump pump discharge piping systems.

Installation Notes

Installation is typically performed by a licensed plumber. Disconnect power to the sump pump before beginning any work on the discharge line. Verify the valve flow-direction arrow is oriented correctly with flow moving away from the pump. Local plumbing codes, including applicable IPC provisions, may govern check valve placement and pipe support requirements on discharge runs.
