the water pressure incresses every day to the red level (high level 2.6 Bar)area
however I let water out every day to reduce the pressure.
please could informe me whre is the problem.
Could be a few things;first is the filling loop definately shutting off?remove one end of hose if external loop to check.Does the pressure only rise when heating is on;if so it is probably an expansion vessel fault; either it needs recharging to 1 bar pressure or the pipe to vessel is blocked or the expansion vessel is gone.
