A couple of quick plumbing questions (water and central heating pipe runs)

[richards1978]

Good morning everyone,

We've recently had the subfloor in our hallway lifted to replace a few bad joists, and I have a couple of questions about the pipes it uncovered if anyone can help:

1) Some pipes run across a few of the joists in notches cut in the tops. It looks like some carpet offcuts have been put in the notches to cushion the pipes.
Is this acceptable or is there a more appropriate/proper lining that should be used instead?

2) The central heating pipes and hot water tap supply all run really close together (about 1 inch apart in a row of three pipes), with the cold water tap pipe spaced about 8 inch further away on its own. This seems reasonably to me, as it keeps hot and cold pipes apart, but is it OK having the hot water tap pipe running alongside the central heating pipes?

The pipes must have been like this for 20+ years, so obviously can't have been too much of a issue over the years, but one of them is weeping around a joint so we will have to get a plumber out to fix this and if there are better ways to do either of the above it would make sense to get this taken care of whilst the floor is up and a plumber is out.

Thanks
Rich

Yes, why wouldn't it be?

It's fine, much better than nothing.
