Bleeding Rads

[Sweater]

I can someone help I had a leaking elbow on my CH system drained system down filled it back up but it took ages very littel pressue coming from the air bleed screw with next to no water this was from all RADs upstairs. Still never got there

Turned the heating on but nothing is there a cut off in the boiler when bleeding down it's a BAXI normal boiler not a combi

Any Idea's I just think it's full off CRAP!!!!

Check theres water in your f&e tank in the loft first. If there is then it points to a blockage in the cold fill, usually where this t's into the main pipe work.

Turn off cold fill gate valve and crack the bottom nut open. Put bucket under it and open valve. If you get full flow then blockage will be as above.

If you ran the boiler with little or no water in then yes-the overheat may have tripped.

 

[corgiman]

what boiler do you have?

A rubber tube over the end of the blowtorch (simple modification) and shoved down the cold feed will clear a blockage if the c/f enters the return.

More difficult on some other pipework configuration.
