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.
they worked perfectly fine before.
i have bleed them again and started to get some warm water through pipes. stop bleeding and it goes cold.other rads downstairs are all working fine. water from rads in slightly dirty.
these where the rads i drained down to.
