Putting new main into house

[outsider]

Hi
I am about to put a new water main into my house so that i can get rid of the lead pipe that is there now and get connected to a higher pressure water main (ok i will not be doing this bit the water bouard will), but can you give me some advice as if i dig a trench down to the depth of the old one from the boundary to the house get the pipe under the foundations , can i then just lay the pipe on the sub soil that is under the house or do i have to bury it as deep as outside the house,
I ask this because the pipe will be coming into the house in a different place to the old one

Thanks in advance

Pressure is the same, flow rate will increase.

Must be greater than existing depth (which is probably 12 to 18") you must go between 900mm and 1250mm unless you obtain prior
permission to not comply.

You can lay it in the dirt under the house but after it enters the house and before it rises to the heated zones it has to be lagged.

The folk who come to conect it will probably not give a monkeys what you have done if what you have done is about right.

For goodness sake use a proper stopcock and place it somewhere accessible, put a drain off above it. If there is copper plumbing internally main bond it with 10mm to the main earthing terminal appropriately labelled.
