Hello, draining central heating system for second time (first went fine). Hose to lowest rad, trvs removed so valves should be open. Drain feed stopped spouting water yet one rad is still bleeding through the top valve, I took a bucket from it! This rad also has a drain off valve at bottom which I attatched with some suction but it's not pulling through either.
Another rad at mid height was also a pain, it also had a drain valve but I did empty this one.
So what gives, all bleed valves open, draining valves open, yet its still pushing out of the bleed off valve in the top (I guess suggesting water feeding to this one).
Tried to find an old water pump but no avail, anyone got a suggestion its a bloody pain!
