Hi all,
I have a gravity fed system, I have removed a few radiators in the house to flush the sludge out as there were cold spots on them. I also did a full system flush with cleaner and with a preventer from Screwfix.
The only thing now is trying to bleed the central heating pump. It is a grundfos installed in a downward flow.
I have tried to bleed it with the large silver screw but it doesn't seem to get all the air out. The pump is working and getting the water to the radiators but it's not at full efficiency.
I had an idea of jeryrigging a hose to the bleed hole to attempt to force water in while the pump is off to push the air back up the pipe or to attempt to suck the air out.
Is there anything I'm missing or that would be easier to bleed the pump?
TIA, Tim.
