Im in need of a bit of advice with trying to drain my system down.
Its a fully pumped system.
The system does not have any drain off taps so i've used a rad valve with a compression nut and a short length of pipe to make my drain off
heres what i've done so far:
-switched off CH
-set both motorised valves to latched open
-drained a s ingle downstairs rad ( the one where ill be draining the rest of the system from)
-drained all the upstairs rads (all upstairs air vents are open)
the problem im having is that after the flow of water from the upstairs rads stopped, I moved down stairs to open the air vents on the down stairs rads however, instead of sucking air, in the down stairs rads are spitting out water and not draining.
(The TRV's and the lockshields on the downstairs rads are fully open)
Anyone got any advice on what i need to do.
