glowworm combi boiler/pressure

[chelly]

hi.my wife recently topped boiler up with water using filler pipe,but she managed to put to much water in.the pressure gauge went up from 1(which it as been set at) to 2.5.When boiler was turned on the boiler overflow pipe was letting water out,so i drained some of the water out of the rads to bring pressure back down to 1.when the boiler is turned on again the pressure needle goes into "red area"about 3.we turned boiler off(central heating)but instead of pressure going back down to 1 it stops at about 2.5.any ideas?do i need a plumber?.thanks.mark.GLOWWORM SWIFTFLOW 80 HONEYWELL

Is the filling loop turned fully off?

If so, look in FAQ's for checking the expansion vessel.

hi dave.me again.set bar pressure to 1bar( centrel heating off).what bar pressure reading does it go upto when central heating is on?

Depending on the size of your system, anything up to 2 Bar would be considered normal.

If it rises quickly to over 3 Bar or thereabouts, you need to check the FAQ's on here for how to check your expansion vessel.
