Boiler Pressure and Central Heating System Pressure

Boiler pressure stays too high. If your boiler pressure stays too high despite water being drained out of the system via a drain cock, there is a fault. In this case you should check where the safety pipe from the 3 bar pressure relief valve dumps its water. This is usually directly outside through a
