Hi,
Wondering if anyone can help wi this?
Drained system via combi boiler valve. Opened bleed valves upstairs(1 in attic conversion and 4 on 2nd floor) no water coming out. Left for a good wee while, closed and went downstairs. 4 rads on ground floor still had water coming out when opened bleed valves???????
Ended up removing rad on ground floor(which was whole point of operation) due to cold spot. Left trv and lockshield valves open. I drained a further two and a half buckets(over 20 litres) out of system via old chinese container.
Flushed out rad with cold spot and re-filled system.
Anyone got any idea why system not draining fully via boiler(drain point is lower than ground floor pipework)? I was intending putting some fernox cleaner in next then inhibitor. Might not bother as instructions with cleaner say to refill and drain a few times to make sure all cleaner out of system then stick in inhibitor. Might just put inhibitor straight in now.
Might be worth a cuppa and bacon roll for best answer if local.
Any advice greatly appreciated,
kerjak.
