I had to drain down my system yesterday and when I went to re-pressure it was not filling.
In checking I suspect that the valve is jammed inside as I have removed the grey handle and used a spanner to turn it. Also If I remove the silver hose and open the other valve I get water flow.
Is there anyway to re-pressure the system in this state?
Can I use out the hose onto the other side and if so how as it is a smaller connection
