how can i fix my water pressure problem on my Vokera Linea Max combi ?
water pressure continually drops from 1.5 bar to zero over an 8hour period & has to be re-pressurised. Boiler techs reckon the boiler (8 yrs old) is ok and may be the water/central heating ? I have no leaks that I am aware of, water meter shows no movement which would indicate usage, any ideas ?
