Can anyone help? I am installing a power shower and had to re-route 22mm pipes that were under the bath. The pipes lead out from the top of the boiler to the PRV/motorised valves. I refilled the system from the mains at the lowest point etc and bled the rads, however the boiler is not "firing" up, consequently I`ve got no hot water and heating. The boiler is a Baxi PF 40, about 8 years old on a indirect system, and was working ok until I started working on it.
Any advice on how to fix this problem would be greatly appreciated
