Hi all,

Having opened up the bottom of the box around the soil stack in my
downstairs toilet, I was delighted to find everything in there all damp
and manky. Peering up inside the box, I can see this:-

My untrained eye leads me to suspect a drippy leak in the lowsest
(closest in the photo) waste pipe joint (

Obviously I need to open up the box near the joint and sort it out, but
what's the best plan of attack? I have some Fernox LS-X left over from
another job and I'm tempted to just seperate the joint and splurge some
in. Is that doomed to fail - especially If I can't quite dry everything
out first? Is there another sealer I should be using instead?
I really want to avoid replacing the fitting on the stack if I can...

Cheers,

Colin.

These fittings often have a ribbed rubber adaptor - maybe thats the problem.

Failing the LS-X is wonderful stuff!

I had similar. Simply kept filling it, wet or dry, with silicone, till
it stopped.

Sounds promising. I was hoping that water (using the word loosely)
wouldn't be too much of a problem for the goop.

Yep. I've had some of the others apart on this stack in the past. They
have an o-ring thing. I've always been impressed that they hadn't leaked
either before or after I disturbed them. They've just gone down in my
estimation.

That's what I wanted to hear )

I got round to hacking a big hole in the top of the box today and took
the offending joint apart. The O-ring looked fine once I'd de-scaled it.
I filled its groove with LS-X and pushed the waste pipe back in with
more LS-X for good measure. It all looks lovely, but for the fact that
it's still weeping. (

Now I can see it close-up, it looks like the boss pipe might be cracked
where the boss joins it. I'll try more LS-X, but it looks like I might
end-up having to replace the boss pipe. Bugger.

Cheers,

Colin.
