Our neighbours have a leak somewhere under their house between the
stopcock
in the street and their internal stop tap.

Insurance company want to internally sleeve the main (which is black
plastic) presumably with another plastic pipe, and hopefully join
everything up at the internal stop-tap. A complication is that because of
extensive modifications, this stop tap arises in the middle of the kitchen
so a considerable amount of wooden flooring will have to be lifted.

Anyhow, Im wondering (just as a nosy neighbour) how much this is going to
harm their water flow. Theyre talking about using a 20mm pipe as a sleeve
but whether thats internal or external I dont know.

I must admit if it were my house I think Id prefer a new main laid from
the street than a sleeved down one, especially if my insurance was paying
for it.

What do you think?

I agree on the new main, but there isnt any way to force the
insurance company to do that if they refuse to do it that way.
