Cleaning CH system using Sentinel X800

[Robert Needham]

Yes I did look and clean the magnet, which didn't seem to be very magnetic to me, it must be working, as quite a lot of sludge around it
I gave it a good clean, so hopefully, it'll still be working well.
Still on high at the moment. One hour gone, I'll leave it running for another couple of hours, then flush it out again
I have already run the hot water through the Exchaner plate for 30mins, doesn't appear to be blocked (yet )

Sorry, meant to say....
As it was pretty clear when I drained it, do you think I'll get away with just filling straight away with sentinal 100?
after I've drained the X800?

You have to rinse all the X800 out.

I did say AFTER I've drained the X800
I realise I have to drain that all out, just wondered if just draining it all out will be OK to fill with X100 as the system was clean on the first drain off..
It's such a pain getting to the drain cocks in the lounge and Kitchen (down feeds)
