Main Description
Switched the pump on or off by detecting the change in pressure of the water system. Fitted in-line, the Whale pressure switch provides a simple and convenient way of creating a pressure system with an electric pump that does not have its own switch. The pressure switch is normally fitted close to the pump on discharge side (before any in-line Y piece). The pressure switch detects the opening and closing of any tap in the system. An in-line filter is recommended on the inlet side to prevent dirt from entering the pump or switch.
