Chaffoteaux et maury Britony combi 80 C12 type?
The water pressure on my boiler has gone, when I turn the hot tap on the bolier surges up but I get no hot water. I think the water pressure has dropped. I want to know how to increase the water pressure please. I have looked online at the manual but cannot find the information on how to alter the water pressure. Pleasde can you help.
