I am a CH novice, and am trying to logically diagnose a problem befor
calling someone in, but am stumped...
3 radiators in one part of the house refuse to warm - even slightly. have:pressure through them
out when bled, and stop when valves turned off - BUT can hear no pum pressure when valves turned on or off
Only common factor of all 3 is that they seem to be fed from upstair pipes separately to other downstairs radiators which are fed from clos to the boiler.
There is only 1 pump and the normal 3 way valve.
Any ideas? I am reaching for the yellow pages now
