Airlock in microbore

[Nixienooz]

]I have an airlock in my microbore central heating pipe which feeds the two radiators in my lounge.

We have no bleed off valves in the pipe which runs in the cellar to feed the two rads.

Both rads have hot feed pipe but the return is cold.

Can I perform a backflush if I remove one of the rads and put hose on pipe??

Help?

What was that answer Chris?

Turn all your working Rads off and,
leave the two not working on

And then what????

And then what????

See if the 2 get hot

If there really is an airlock then the air will be displaced into the radiator and can probably be bled from the vent.

I suspect its sludged up though!

When we turn all the others off we have a horiific amount of banging in the pipes which then causes the boiler to trip out....this is just repeated each time we try...

What a nightmare!
