Pipe depth issue

[piercedpipe]

Hi all,

Want to replace my existing 15mm shared water supply for obvious reasons. The current supply in my 1935 built house is around 150mm below ground level outside and around 450mm internally (no DPM).

My issue is, for me to enter the house 750mm below ground level outside, I will need to drill through the foundations. Will seven Trent expect me to do that? Foundations are around 650mm below ground level externally.

Thanks in advance

yes also you will have to sort the pipework out they will just connect there side eg stop tap

unless your paying them for the whole job?

If your foundations are only 650 deep, then surely you'll be drilling under them rather than through them?

Thanks, was hoping I wouldn't have to do that. All seems very extreme as never had issues with current supply freezing, and as afar as I know, UK has never had a frost below 6 inches.

Usual overkill to charge more I think.

2'6" was in the 1950s model water by-laws, so nothing new. Probably also something to do with keeping the water reasonably cool in summer and to avoid drying and wetting of the ground from stressing the pipe.

also less of a risk eg damage from people digging

True, but since gas pipes are allowed to be much shallower, I wonder if this was the thinking behind the rule.
