Does an inhibited system generate enough sludge to warrant a

Is the Magna booster a reasonable trap? (seems likely enough,
although massively over-priced) Is BG installation fee reasonable?
(seems equally massive, IMHO).

I put a Magnaclean on my mum's CH - when I swapped the boiler I spent
a long time flushing the system through, and I then followed the
Keston advice to add a Y-strainer. Every few weeks this would clog up
with something the consistency of grease. In the end I took it out
and replaced it with a Magnaclean which doesn't obstruct the flow as
it collects stuff.

Yes, I know that this shouldn't be necessary in a perfectly sealed
system, but in this case some of the under-floor pipework dates back
to the 1960s, compression jointed. There's no major leak - system
needs a top-up every few months. Ideally the pipework should be all
replaced and the system zoned, but with laminate and vinyl floors the
disruption would be horrendous.

Have you tried putting leak sealer in? It can bung up small weeps.
