When the weather is dry, sometimes a probe pushed in at intervals will
suddenly show up a wet spot near the leak if its been leaking for some time.
Unfortunately if it goes under buildings... ouch.

What the best (but cheapest) way of tracing a mains water pipe in the
ground on private property.

Is ther any thing I can buy, relatively cheaply ??

Anyone just reading this now, re plastic water pipe, if you an an idea
were it is likely to be you can use fencing wire to gauge the length,
curl the end of the wire round neatly and tape it so it does not chafe
the pipe, disconect the mdpe pipe at a accessible point and feed the wire
down, if there are no other services near such as cables you may with a
good detector be able to find the wire, alternatively hire a 'CAT SCAN
and GENNY' you connect the genny to the fencing wire or other wire you
have put down the pipe, this generates a radio signal and the cat scan
detects this very easily, playing with this i managed to locate a 32mm
mdpe plastic pipe all the way from my house under the garage floor and
across my paddock for about 50yds the pipe was burried 2 feet down, 3
feet under the paddock. you can also locate plastic drains this way.
Where i drew my line maker paint when i dug the hole it was within 2" of
my line


Our neighbours are waiting for this as I type. They have a leak in their
incoming mains but no idea where the pipe runs as the house has been
extended many times.
