when the boiler is working the pressure starts to rise and c0ntinues to. i keep lowering the pressure via bleeding a rad. have renewed the water inlet valve and disconected it but it still keeps rising.....worcester combi 28cdi
What is it rising from to?? should be 1 bar when cold, could be upto 2.5+ bar hot, depends on system design etc IT should not go over 3 bar, as you have a pressure safety valve, which releases at 3 bar.
