1. You need to specify the model, and preferably year, of the boiler, as some Worcester Bosch boilers are so constructed that the boiler needs to be removed to fix the pressure relief valve (PRV). 2. If its is still leaking at 1 bar pressure, then you will almost certainly need a new PRV.. The Worcester Bosch spare pressure relief valve is designed for use with Greenstar and Greenstar ErP appliances. The pressure relief valve helps to control pressure in a closed system by proportionally opening to relieve excess pressure, preventing catastrophic malfunction. Operating pressure is 3 bar. Manufactured with black plastic.
