Boiler Pressure

[andygb1970]

Hi Guys,

I recently had the Pressure vessell and diverter valve replaced on my Worcester 28cdi boiler (three days ago actually).

The engineer set the pressure at 1.5 bar, but it has gone up to 3 bar now. These were the symptoms of the boiler before the work, as well as hot water enetring the heating system although set for summer etc.

Please can anyone give me an idea why this is still happening. I have contact the water board, who say the mains pressure is ab it high, and is 6.5 bar.

Thanks for your replies in advance.
