Has anyone ever come across this.
I have filled my Valliant ecotec plus bolier using the 2 valves underneath and the filling loop.
Opened both valves , system filled OK - all good
Problem is , I now have cold water running fine through the taps but when I turn the tap to hot , the flow dries up ! on all taps
I noticed that I had only closed the left hand filling valve on the boiler
When I then closed the right hand one too , the hot water sprung into life !!
Any ideas please ????
