How to fill around main copper water pipe

[jawilba]

I'm in the middle of doing so home renovation and needed to move the main water pipe coming into my kitchen.

I had a plumber come and move the pipe but I now need to fill what has been dug up. He has taped it and said I will be fine just the screed over it but I should put a bed of sand underneath pipe to make it easier to dig up in future.

I was just going to fill the hole with like for like concrete mixes, put sand under pipe and finish with a weak mix on top incase I needed to get to pipe in future.

I've checked online and most info advise against putting copper in cement directly and should be in an outer pipe / conduit.

I was thinking of buying some corragated conduit pipe and cutting lengthways to slip over the pipe then filling.

Would either of these be ok or is there a better way?

Here are some pics.

That tape (looks like masking tape) is insufficient. Have a read of this, it should give you some more information and guidance:

I've put some conduit around the pipe to provide some more protection.

I just need to bury the pipe now.

I was going to fill the hole with like for like with what is currently there but the only concern I have with this is that there will be a joint in the floor screed.

Should I just bury it or should I try and retain access if needed. The majority of the pipe will be under a kitchen unit but the deep whole where the pipe enters the kitchen will need filling or someway to protected it as it will be walked over.

Thanks again for the help.

that there will be a joint in the floor screed

Joints aren't allowed to be embedded in floors or walls. It should be in a duct or similar to allow access.

If I were to fill and make a channel around the pipe and then bridge the pipe with ply or steel would that be ok?

Yes, but strictly speaking it should remain accessible with a removable cover. If not it should be fully ducted so the pipe can be pulled out for inspection.

Good guidance in the link provided earlier https://www.wras.co.uk/downloads/pu...lets/para_7_guidance_version_2_july_2014.pdf/

I have looked through it. That why I suggested making a channel and covering it.

Think it shows what I mean in image g7.1b?

The joints below floor level are soldered. The flooring will be laminate so removable if needed. So unless a good reason not to I will make a channel around the pipe and joints and cover which will be flush with floor. Material I use for cover will depend on how much space I have.
