Rectorseal CV01.5 Sump Pump Check Valve 1-1/2 Inch

Product Description

The RECTORSEAL CV01.5 is a full-flow check valve designed for 1-1/2 inch sump pump discharge lines. Built from ABS thermoplastic, this valve uses a flexible rubber flapper to create a positive seal that prevents backflow when the pump cycles off. The inlet features 1-1/2 inch male threads for a secure threaded connection, while the outlet is sized to accept 1-1/2 inch flexible discharge hose. Plumbers and pump service technicians install this valve as a standard component in residential and light commercial sump pump systems to protect the pump from reverse flow and water hammer stress.

This check valve is suited for residential sump pump installations where a reliable, low-restriction backflow preventer is required in the discharge line. The full-flow internal design minimizes head pressure loss across the valve, keeping pump performance consistent. Its compact, lightweight construction at 0.217 pounds makes it easy to handle in tight sump pit enclosures and crawl space installations. The rubber flapper closes quickly on pump shutoff, reducing water hammer and extending pump motor life.

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 1-1/2 inch sump pump discharge systems using threaded pipe connections and flexible discharge hose.

Installation Notes

A licensed plumber or qualified pump technician should install this valve. Disconnect power to the sump pump before beginning any work on the discharge line. Hand-tighten the threaded inlet connection and apply thread sealant tape to prevent leaks; do not overtighten ABS fittings. Ensure the valve is oriented with the flow arrow pointing in the direction of discharge to allow the flapper to open correctly during pump operation.
