Hi everyone,
I have an open vented system with a 3 port valve.
I aim to drain my system and add inhibitor as I have been treating it for the last fortnight with sentinel x400.
After checking the motorised valve I found that the manual lever was floppy but I expected it to have resistance to move the valve.
As there is no resistance on the lever I thought this may point towards the valve being stuck but my heating and hot water work ok.
Any ideas would be much appreciated.
