Check the inner body around the seat for signs of wear or cavitation damage. Check the resilient seal on the lower seal disc for wear or damage to the rubber. Check the inner diaphragm inside the upper side of the actuator and replace if necessary. Check the indicator (if fitted) for leakage through the shaft.

Pressure relief valves: These are typically installed downstream of each pressure reducing valve. · Pressure restricting devices: PRDs reduce pressure only when 

Keep Water Under Control With Pressure Relief Valves & Regulators. Limit the flow of water with a pressure-reducing valve. This device works by limiting how much pressure is inside the valve, causing friction and reducing the speed of the water that travels through. With a pressure relief valve, you can modify your network of pipes so that
