Please bear with me I'm going to try and give as much detail. Covered by British Gas who appeared and disappeared saying the the problem was due to blockage therefore not covered, quoted a silly price for a system flush (10 Rads) and then quoted the Earth and the Stars for installing a New Two Pipe System. I'm a normal Joe with a wife and three pan lids afer crimbo they're having a giraffe?
Back Boiler, Single Pipe, Gravity, Vented system (cold water expansion tank sits on top of the Hot water Cylinder). New Years eve the CH/HW system shuts down.
Discovered, that theres a blockage in the CH heating system starving the boiler of water shutting the burner down. Removed circulation pump discovered from the Radiator(s) side of the pump 'nothing' from the boiler side 'Gushing (black coloured water)'.
Reverse fitted the pump to circulate the water the other way around, No Joy. Still nothing coming from the Radiator side of the pump.
With the pump removed and isolation valves operated in sequence Attached Garden Hose 'mains water pressure' to copper pipe fitted Radiator side of pump. No Joy. Removed and refitted Garden hose to Heating drain Valve fitted to boiler side of pump. Forced water into system through boiler hoping to the see water come through the return 'radiator' side of the pump. No sign of water coming through the return pipe but notice water level rising in the expansion Tank (above the hot water cylinder). Did a bit of reading which said plug the F&E pipes. Did this and continued to force water into the system via the system drain valve. Clyinder made a noise like a pop (as if you were pushing out a dent in a panel), 'bobbed myself' and stopped the process.
Am I on the right lines ?????? blocking the F&E pipes and ignore the 'deforming' noises??
Thought the Hot Water would be sorted by the immersion heater. After having the thing on for 6 hours went up to check the tank, stone cold. Checked voltage to the element 'dead' . Thought maybe a wire had come lose from the back of the switch only to discover that wires come up from the fuse board. But, no wires leading from the switch upto the element. A very pretty neon light comes on.
Once again am I on the right lines ?????? blocking the F&E pipes and ignore the 'deforming' noises?? Just looking for a little guidance to get family life back to a level of normality.
Cheers
