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.
