Timeserved plumber of 6 years, always have a look on this site but never had the need to ask as always someone else has the problem and i just look through that thread..........
Now, i have recently went to a central heating system, 26 years old
Radiators stopped working all over the house after a radiator that had been off for over 2 years was turned on
So changed the pump as it was making noises and at 26 years old it would not do any harm
2 radiators upstairs and a towel rail now working with new pump, downstairs not, so turned upstairs off, downstairs still not heating up apart from one closest to the boiler but only the flow pipes warm
So i turned a radiator off, took off the plug at the top and connected into the mains water system and blasted some water in to see if i could shift air. FAIL
Now ive traced all pipes and its just not wanting to go round the downstairs circuit, i listened to the coil at the cylinder and i would certainly say the pump is pumping round the coil which it should not be doing as its a gravity hot water/pumped heating system.
Is there anyway of stemming the flow to the coil other than put valves on and close them off a little??!!??
Any other suggestions welcome, no matter how silly they might seem, please ask anything!!!!
