Whale Inline Pressure Switch

Switches the pump on or off by detecting the change in pressure in the water system. Fitted inline, 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 inline Y piece). The pressure switch detects the opening and closing of any tap in the system. An inline filter is recommended on the inlet side to prevent dirt from entering the pump or switch.
