BG came around to my Mum's to look at her combi which wouldn't

Apparently some crud in the valve which they sorted and to their

are pushing a system "power flush" for £600 which sounds a lot to
me. Assuming I'm prepared to spend a day messing around looking for
drain cocks and bits of hosepipe, is there any reason I can't do
this myself?

Is there a recommended flushing substance to treat the system with
prior to a full flush?

I've read that a power flush finds leaks in rads which if left alone
would not be leaking.

If they are that knackered, they soon will be - power flush or not.

My rads are old as am I. My rads get Very hot. If it's not broken
