baxi combi instant 80 he water pressure has dropped to 0 ?
ive just bled one of my radiators and now my baxi combi instant 80 he water pressure has dropped to 0, how do i increase water pressure(the pump is okay.)?
there is a filling loop on boiler, either external hose or an internal one worked by a plastic key. simply need to fill it to the pressure in your manufactueres handbook.
