Somehow the porcelain waste pipe of the toilet has cracked and has started leaking. We're about to replace the whole bathroom so I just need a quick fix. Will wrapping the crack in duck tape work?

Fortunately the inside drain of a toilet is not pressurized, so thick globs of plumbers putty will do the trick until you eventually replace the toilet, but PLEASE keep in mind this is a temporary fix. – maple_shaft Oct 17 '12 at 18:23
You're talking about part of the toilet itself, not the underlying plumbing? – The Evil Greebo Oct 17 '12 at 18:23

@TheEvilGreebo yes, it's the part of the toilet just before it attaches to the waste pipe. – snowdude Oct 17 '12 at 22:18

Epoxy putty, found in the plumbing repair section or adhesives section of your local big box store:

It's a two part compound that you work together like clay. Blend a small amount, per instructions, then force it into the crack, ensuring it completely fills the crack.

Many thanks, hadn't even heard of the stuff before. Will try that. – snowdude Oct 17 '12 at 22:18
