Nonstock 20PMPD2WP Tether Float Switch 230V 15A Normally Open

Product Description

The NONSTOCK 20PMPD2WP is a normally open tether float switch rated for 230 volts AC and 15 amps, designed to automate pump operation in liquid-level control applications. Part of the PumpMaster Plus series, it uses a wide-angle tether float mechanism that activates at 45 degrees above horizontal and deactivates at 45 degrees below horizontal. The float and body are constructed from PVC, and the mounting bracket combines ABS and stainless steel for durability in wet environments. A piggyback plug connection allows the switch to be wired in-line with a pump cord without additional wiring hardware. It ships with a pipe clamp for hose-mount installation.

This float switch is suited for residential and light commercial sump pump and sewage pump applications where automatic level-based pump cycling is required. The adjustable pumping range spans 7 to 36 inches, allowing installers to dial in the on and off water levels to match the pit depth and pump capacity. The SJOW-rated cord handles the wet, subterranean conditions typical of sump pits and sewage basins. Plumbers and pump service technicians are the primary installers for this type of control device.

Installation Notes

Installation is typically performed by a licensed plumber or pump service technician. Disconnect power to the pump circuit at the breaker before handling any electrical connections. Secure the hose clamp mounting bracket to the discharge pipe or pit wall so the float hangs freely without contacting pit walls or the pump body. Verify the finished on and off points by manually cycling the float through its full range before restoring power.
