Yea right , dig up the slab and replace it.. It was a matter of time
before ou just had to reply to something you have no knowledge
on......true to 99.99% of your other posts.

Inside of PVC pipe is certainly far from being uniform, so its
impossible to slip a device inside yet alone get it to where it has
to be and ensure your surface to seal against is dirt / scum
free.....anything placed inside is going to be a potential for buildup
of junk and make a restriction......Now if your systems flow is more
than you need, you may be able to push another pice of pvc pipe
inside the leaking section provided you have a straight shot at it,
but it would be conter to making a good repair which is going to
involve getting to the leak itself and that may entail busting up the
concrete. Yea, people on slabs wind up busting slabs
its part and parcel for having lines buried in or under conrete....

Just found out that one of my cemented in pipes are leaking. Does anyone
know of a pipe sealeant that can be used (bear in minds I can't get to
the outside of the pipe). Or does anyone know of a pipe liner that can
be used?
===================
Contact your local plumber before doing anything drastic. There are new
products out there every day. People who have houses on slabs probably face
the same problem when a pipe leaks.
