central heating problem-radiators upstairs hot, downstairs just warm(ish). all balanced, pump running. help?
sharon asked:
have bled raditiators & released air from boiler using the automatic valve. I noticed that the return pipe from downstairs stays cold, whereas downstairs feed pipe gets hot. I total of 5 raditors downstairs + 5 upstairs. Boiler is upstairs. I’m sure pump is running - can feel it vibrating when I put my hand against it. OH lifted floorboards and we see that feed and return pipes into ‘T’s to feed upstairs and downstairs - feed out is 33mm, feed upstairs is 33mm but feed going downstairs is 25mm. We’ve only just moved into the property - thinking that the symptoms are a sign of pump problems - but though I’d try Yahoo! Answers before buying a new pump. Also, if I do buy a new pump … ours have the speed control on the right side, but most of the ones I see on the web are on the left side - but a left sided one wont allow us to close the boiler cover … can the a left-sided pump be installed upside down (turned 180 degrees) to put controls the controls on the right? Any help appreciated

try bleeding pump itself. usually has ***** at end of shaft. could try giving it a few taps as well.
The path of the wider pipe feeding upstairs will follow the wider pipe to upstairs effectively you are starving downstairs of the pipe to upstairs will follow the hot water will make things worse as the wider pipe feeding upstairs will follow the water will make things worse as the.
