I have a Potterton Suprima 40 boiler. Yesterday the auto air vent valve started leaking after which the system shut down. I cannot find the pressure gauge or the valve to restore the system pressure.
I have a problem with my Suprima40 boiler. The auto vent valve started leaking after which the boiler shut down with the flashing red light. I know the system has lost pressure but I cannot see the pressure gauge or the valve to top up the system.
