Cured?

Living room floor flooded yesterday!

Decided it was consequence of bath emptying upstairs. Flushed blocked downstairs toilet out. (Was clean water as I'd plunged it and scooped water out manually before putting some organic deblocker in).

Today think it may be OK to use toilet, but not dared try it yet.

Seems unlikely to have cured itself like this - not my sort of luck!
