Drain down rads from a megaflow

[Alan Cordt]

Hi all

I was wondering how i would isolate the flow to the radiators in a house which has a megaflow system.

I need to move the flow & return pipes to the opposite side of the room to install a new rad.

Any help would be great!

Thanks.

Alan.

The boiler is probs on a pressurised system?

Just drain down from a point lower than your working, then refill system through filling loop.

The megaflow part of your question is irrelevent, if im understanding you right as this refers to the type of cylinder you have.. no?

Yes it is irrelevent sorry & thanks for your help!
