Star Water Systems 024777 Pressure Relief Valve 1/2 in 70 Psi

Product Description

The STAR WATER SYSTEMS 024777 is a low-lead pressure relief valve designed to protect water well pressure systems from overpressure conditions. Sized at 1/2 inch pipe thread and factory-set at 75 PSI, the valve opens automatically to relieve excess pressure before it can damage the tank, pump, or associated plumbing. With a rated discharge capacity of 1,200 gallons per hour at 70 PSI, it provides meaningful flow relief during pressure excursions. The valve weighs 0.438 pounds, making it compact and easy to handle during installation. Plumbers and well system technicians are the primary installers of this valve in residential and light commercial well water applications.

This pressure relief valve is intended for use in any water well system capable of producing more than 75 PSI at the pressure tank. Typical installations include submersible pump systems, jet pump systems, and other well setups where pump output or system conditions can drive pressure above safe operating limits. The low-lead construction makes it suitable for potable water systems where material compliance is a consideration under applicable plumbing codes.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC) where applicable.
