When the filter or strainer of the pool pump is blocked, this increases the water pressure in the pump, which can damage it. You can reduce the pressure in your swimming pool pump by cleaning out its filters. Turn off your pool pump and filter. Open the pressure relief valve to lower the pressure in the pool pump. When the valve is opened, water will be emitted but will slow to a trickle and stop after a few seconds. This is normal.
