Draining rad circuit in reverse maisonette

[Best]

I would be wary of having hoses lying across ground and pathways for some clown to trip over and try to claim from you.

Indeed it's a busy part of town too. A drill pump into the bathroom seems like an option if I can't get a decent symphonic route, can get drill pump for £20

Drain all you can with a hose, then use a WET VAC.

And before you do any work in the lower level, check you can safely get out through a window in an emergency.

And if you're going to be using a blow lamp, a Fire extinguisher would be handy to prevent that possible emergency in the first place

Try not to get any sludge on the beach, don't want that on my budgie smugglers.

Why not drain the top half like normal and the bottom half into a few buckets via a rad valve. Won't take long at all.
