failed rads

[paulo3]

I am in the process of installing a new bathroom and as part of the work I removed the old bathroom rad and made all ends good.

Problem:
none of the upstairs rads will now work. I think it's an air lock (guessing?) but bleeding does not seem to work. I did drain down before removing bathroom rad. Have tried draining & re-filling twice since without success.

Anybody any ideas?

TIA,

paulo

could be the rads are on a one pipe system so you now don't have a circuit just 2 dead ends.

Try backfilling with mains water via hosepipe connected to rad drain cock.
