All NEW Aston Martin Pressure Relief Valve
Over time the original valve will deteriorate and release pressure prematurely, causing the system to depressurize rapidly and increase pump cycle time.
Warning: This is a high-pressure system; before doing any service, it is imperative to ensure no residual pressure in the unit.
Note: If you need us to calibrate pressure, please advise us, and we will perform calibration free of charge before shipment.
