Sorry this takes a bit to explain but I will try and keep it short.
Last weekend, water started leaking from the bottom seal in the central heating pump. Called plumber and I drained the system. Plumber came and fitted new pump (plus two new isolating valves above and below the pump) Re-filled system. Cylinder filled with hot water fine the next day when hot water was switched on. That evening, came home from work and tried to get rads to work. First rad in the system got hot but all other rads were cold. Bled rads and all have water inside. Checked F&E and all appeared okay. Guessed there may be an airlock somewhere in the rad pipework. Off to work the following day [intending to try and sort the rads out that evening] and, when I came home, 'er indoors' told me there was no hot water!
As it had been very windy, checked to see if pilot light had gone out. Nope - pilot okay. Switched on for hot water and back boiler fires up then cuts out after only a few seconds.
Called plumber in case he knew where the fault may lie (I assumed it wasn't the boiler hence why I called the plumber ) He suggested an airlock and to run mains water back via the draincock on the lowest radiator to try and clear it.
Now it could be sheer coincidence but, given the boiler worked fine for hot water on Day 1 (it didn't cut out after only a few seconds like it did on Day 2) any ideas as to the problem please?
Any ideas would be greatly appreciated.
Thanks
