My neighbours are getting their driveway re done and while digging it up it was reccomended they have an old copper water pipe under their drive replaced. My water meter is right next to theirs outside their drive and I'm wondering the possibility of whether my pipe is under their drive too or if there is any way to find out?

If it does go under their drive and is recommended it is replaced, I'm happy to pay.

Just anxious about discovering a leak later on and have a large bill to dig up a new driveway to fix.

I think you can contact the water supplier and ask for a map showing supply and various drains.

Without a picture it's hard to advise

You can hire a cat and Genny to trace your pipe

If it runs under their drive, won't they have found it by now?

It's best seen as a guide rather than accurate, if it's even on the plans

Pipes are usually buried deeper than the depth of a drive - block, concrete or tarmac.

But if they've found one pipe, the other may be at a similar depth?

If you can get under your floorboards you may be able to see where the pipe enters your house, and make an informed guess of the line taken.

I read it that it was at the planning stage - before any work had started.
I may well be wrong!

If it does and you are, get it re routed to somewhere more "accessible" when they lay in the new pipe, don't just get it replaced.

metal detector might help as a starter i.e. If it picks up their pipe but nothing else

At 0.75m deep you'd be lucky

The drive was just concrete before. The concrete has been removed so just the hardcore there now. I've asked them to ask their contractors/plumber to have a look and let me know.

My mains pipe at the indoor stopcock is lead so guessing it's lead all the way to the water meter too.

Some water companies were replacing lead service pipes for free at one time to reduce the health risk to their customers. Replacing with plastic is fairly straightforward, the biggest task is digging the trench. If you’re not technically minded you could dig the trench (or have a digging party) and get a plumber to do the connection.

Have a word with the water company as they might send someone to trace your pipe for you. They may also have a lead replacement scheme.

More like, contact the water company and they'll send a camera down and charge you a couple of hundred quid to upidate their 'plans'.

LLBUD website will provide free utility prints as a guide. You need to register.

You could just get driveway guys to run a new plastic pipe under the drive from near the meter to a convenient spot on your side, if the water ever needs replacing you know the pipe is there waiting...cheap as chips option and no unnecessary cost or upheaval 'just in case'.

Getting my drive done soon and I plan to install a couple of ducts to future proof phone service and perhaps driveway security lights, might even stick one in simply to pass a hosepipe across to where I wash the mud off my bike 🙂

LLBUD

Can't find the website.

Had a quick look through the gaps between floorboards in the living room at the front lof the house. I can see the lead pipe heading straight towards my driveway but no idea if it goes all the way to the pavement before a 90 degree bend towards the water meter, or just diagonally under their driveway.

The likelihood is that both services could run in parallel and split close to the houses. Trenches are a pita to dig so the builders used to make their lives easy.

Cat and Genny from HSS or similar will tell you. Not hard to use, instructions are on the outside, just make sure you get a good earth.

The likelihood a individual lead service is shown is diminishingly small
