Hi Guys/Girls
My Baxi 105 instants pressure gauge rises to over 3 bar when the heating is on and when you draw hot water or the pre heat comes on the pressure will drop about 0.5 bar. I have checked the expansion vessel and there is no water coming out of the vavle and there seems to be plenty pressure in there
anyone any ideas could it still be the expansion vessel and pre heat store Thanks in advance everyone regards. Cris
