I have no clue about plumbing so just bare with me whilst I try and describe my problem. I have an open fire with a back boiler. Today the pump that heats the radiators didnt work so I had to run off the hot water. I changed the fuse and got the fire going again but still the pump didnt work. I now think it must be something else as my pipes are banging and I can hear a bubbling sound in the pipes near my hot water cylinder. One of the small pipes is boiling hot but the water isnt going anywhere. I have tried running the tap but its cold! Any ideas?
