Grooved Pressure Switch by Whale

The WHALE Grooved Pressure Switch activates or deactivates the pump by sensing changes in water pressure within the system. Installed in-line, it offers an easy and convenient method for establishing a pressure system with an electric pump that lacks its own switch. Typically, the Pressure Switch is positioned near the pump on the discharge side (before any in-line Y piece). It detects when any tap in the system is opened or closed. To protect the pump and switch from dirt, an in-line filter is recommended on the inlet side.
