Water leak outside property

[Bogart]

What is the surface of the route from meter to stopcock?
By which I mean; tarmac, slabs, grass concrete etc etc.

Approximately 35m soil and gravel top remaing 7/8m is patio slabs. I did have a though that if I could expose the pipework in a few places, easier said than done mind, is it possible to hire a freezing machine suitable for mpde in that way I could isolate sections as suggested previously?

So no tell tale “lush grass “ areas!
How far away is outbuilding?
Is pipe mdpe or old galvanised?

Mdpe from meter to house but somewhere it changes to 15mm copper before entering outbuilding. No signs of moisture anytime in summer so no clues there. Have got a guy to come round next week and do a bit of digging so we will see,

You don't need to freeze MDPE, use a squeeze off tool

You'll probably find it cheaper if you search, or make one yourself

Interesting. Says will not damage the pipework how does that work as it squashes it flat?

 

[gmartine]

The squeeze off tool has round jaws and the pipe has some memory and will recover from being squashed.

Leak could be anywhere from the junction onwards, how deep is it buried ?

Good question. Was meant to have a guy around today to dig some holes. He has Covid and his wife was made redundant yesterday hence reason for his non appearance. I will dig a few myself and see where that leads me. I think in this freezing weather I would be tempted to warm the pipe up a bit before I started squeezing it. £26 off *bay so worth a punt at that.
And while I am it I looked at slip couplings the price does seem to vary enormously for the same thing.

Both made by Plasson apart from colour is there any other difference?

Yes as Shaun says, the first fitting you have to buy in the specific size you need, the second is a different design of seal that fits a range of sizes 31 to 35mm. The first doesn't have flexibity for slightly different size pipes. I believe it's a more complicated product hence a higher price.
