How do i reduce the water pressure in my combi boiler turbomax plus 828E. I have tried to bleed a radiator but the pressure goes up after. If the heating or hot water is used the dial goes up to just below the red mark.
This problem occured because the boiler pressure was topped up and wasn't turned off properly so we are without heating or hot water because of the pressure

b careful. very careful here. danger! pressure danger!have air lock problem i think. start at closest rad. 1 at a time remove air till water runs out for at least 1 min w/no air bubbles in it.go to next rad up stream do same . done w/all, repeat same till no bubbles .steady stream a must.!!!!! fuel in off position. just cold water bleed.repeat. repeat repeat. careful.danger!!
