Son (despair, despair) has put a fork through an underground water
pipe. He says the fountain was spectacular.

I remember the pipe in question - it is black and looks like ptfe, and
will have been installed in the '60's. When we had a previous leak at
a short exposed link, we found that the pipe was not a standard size
and I seem to remember finding a farming supplier in Wales who had
some fittings or adaptors, but I have no note of who or where they
were. Somewhere near Ruthin, I think.

For this reason we are loathe to cut and join the pipe. He was
wondering if there was some sort of adhesive that we could apply and
then bind with gaffer or other tape.

I found something online called Universal repair pack from Five Star
Adhesives in Runcorn, aka Starlok, but their site is out of date and
when I tried to make a Tinyurl, I got a refusal and warning of a
spammed site at

Has anyone any experience of this or similar product? Or trying to
fix a pipe in this way?

You can't use tape over a water main, it won't last five minutes, and I'm
wary of any kind of sealant in an application like this.

Why not just get a couple of adapters and a small length of blue mdpe pipe
and join them together?

The adapters are about £3 each, you'll need two and a few feet of blue pipe:

Cheaper than the sealant that won't work.
