I had seen somewhere a powder chemical that could be used when removing a toilet.
Eg, replacing an old, stained pan.
Tear the packet, tip it in, it would make the liquid solid.
So when removing the old pan there wasn't any liquid spilling.
It would think the chemicals used would able to be dumped at a Dump Station.
Members here who are plumbers maybe able to help.
Cheers.
