The EVERFLOW 250S100 is a 1-inch CPVC ball valve designed for use in cold and hot water distribution systems where corrosion resistance and chemical compatibility are required. Built entirely from chlorinated polyvinyl chloride (CPVC), this valve provides reliable quarter-turn shutoff through a socket x socket configuration. The NSF listing confirms the valve meets drinking water safety standards, making it appropriate for potable water applications. Plumbers and pipefitters install this type of valve in residential and light commercial systems where solvent-welded CPVC piping is already in use.
This valve is suited for residential plumbing systems, light commercial water distribution, and hydronic or chemical-handling lines that call for CPVC piping. The socket x socket end connections accept standard 1-inch CPVC pipe, allowing direct solvent-cement installation without additional adapters. It is typically installed in supply lines, branch shutoffs, or isolation points within a CPVC piping system. Its NSF certification makes it a code-compliant choice for potable water service in jurisdictions that require listed components.
Designed as an OEM-style replacement or new-installation component for 1-inch CPVC piping systems using solvent-cement socket connections.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off and depressurize the water supply before cutting into any existing line. Use only CPVC-rated solvent cement and primer when joining socket connections, and allow full cure time before restoring pressure. Verify that system pressure and temperature ratings are within the valve's rated limits before placing it in service.
