Combi boiler low pressure light was flashing,so increased the pressure-but too much(over 2.5 bar) wot do i do?

Question

Hi. The low pressure light was flashing on my combi boiler this morning. This happened a few months ago and asked my brother to have a look at it. He turned a valve/or somothing similar? under the boiler and increased the pressure. So I did the same thing this morning - but I've increased the pressure too much - over 2.5 bars! I quickly turned the boiler off as the pipes started making noises, but I dont know how to reduce the pressure! I am stuck in the cold and dont really know anything about boilers. Can someone please tell me what to do? Any advice will be much appreciated. Thankyou. Sammy

Answer 1

close the valve a little turn it back on, slowly adjust the valve to get the right amount of pressure,

where is all theses boilers being used, i see ? like this all the time, it would tell me to change the type of heat i use,
