In a fluid flow network including a centrifugal pump, a system and kit for monitoring said centrifugal pump and relieving the pump of fluid when the pump is operating at no-flow conditions. The system comprises a fluid conduit connected to the pump, at least one sensor for indicating when the pump is operating at no-flow conditions. The sensor is selected from the group consisting of: temperature sensors, pressure sensors, and motor current sensors. The system has a fluid control means located in the fluid conduit. An electric snap-action valve is included that has an inlet connected to the fluid conduit and an outlet and a diaphragm. The diaphragm is movable between a first position and a second position. A power supply is included.
