Replacing Incoming Water Supply Pipe

[Glyn1959]

Hi, i’m looking to replace my water supply pipe as it’s currently alkathene and has had numerous leaks in recent years.
I asked a local contractor (recommended by my water company) for a quote to lay a new pipe around the premises along to the rear of the property.
He suggested an alternative I.e. trench to the front of the property into the garage and then change to copper pipe through the garage and into the kitchen to the internal stop cock. This would be a less invasive method BUT is it an acceptable alternative? I have never heard of this method before.
I welcome your advice/comments/pros & cons
Thanks

That’s not something I would recommend or do myself. It doesn’t allow suitable access should the pipe need to be withdrawn for examining purposes. Also, afaik you can’t or shouldn’t use copper below ground anymore, could be wrong with that though. Would it be feasible to dig down to existing and renew a section?

You’re just talking about bringing the main into the house at the front rather than the back, to reduce the amount of trenching? That’s fine. Copper would need lagging in garage.
It’s meant to be ducted and insulated as it comes in tho, then a stopcock and drain off pretty close to that point.

The copper would all be above ground (up the inside of the garage wall and across the top of the wall. Due to the history of leaks I want to completely replace.

Apologies, I misunderstood that bit. As above then, it would need to be insulated to protect against freezing.
