This site is in the UK, but I bought a product like this at one of the
BORGS.

The seam around the middle of my PVC Drum Trap
(http://plumbing.hardwarestore.com/52...ap-241364.aspx)
was leaking and replacing it meant redoing all the drains under my
kitchen sink. I figured I would try the putty at least temporarily, but
it's been a couple of years and it's still holding.

It's a log made of two different materials that you blend together by
hand and apply to the leaky seam. If there's water dripping out during
application, you just keep molding the putty in place until it begins
to set up and the leak stops. 15 minute working time, cures in 60.

I have a 4" pvc downpipe which has a swept Tee joint from an upstairs
bathroom.

This tee joint is leaking badly but it cannot be replaced due to the fact
that it is embedded in a concrete pillar.

I have managed to expose most of this joint but do not want to remove the
structural steel work surrounding it.


Any ideas?????
