have turned off all the rads except the 2 not working ( 2 ft away from each other) no heat in rads or pipes.
suspect i have a blockage in pipes, would a couple of drain downs help ?????
hi,
had a leak on a rad valve . drained down system partially as only needed to work on upstairs rad and replaced faulty valve. vlaves on rads are not TRV's.
filled system and bleed all rads and pump ( gravity system)
have balanced the rads but have 2 rads downstairs not getting hot.
