My friends have a Baxi Combi 105e and they filled the water up in the system, but filled it to much and the pressure reads 3.2bar and shoul be between 0.5 and 2.5. How do i bring the pressure of the boiler down.Tried running the hot tap, when turned off, but nothing happening. I f i drain it at one of the radiators will this solve the problem? and will it have to be off to do this etc? Any help would be grateful Cheers

If they find the schraeder valve (like a car tyre valve) on the expansion vessel, press it until theres nothing left in it, then run the boiler on CH the boiler will vent loads of water out of the PRV. Then just re-fill the expansion vessel to desired pressure
