when my boiler starts up it goes straight to 3 bar and releases water through the discharge pipe therefore constant pressure loss in the system and i am constantly topping up the system(i can only top up to 1 bar not 1.5)as it drops to 0.5 bar or lower.Does anyone have any ideas what is causing this.
