Dublin County Council - notice of leak within the boundary of my house

antiskeptic

A friends house actually.

She got a letter saying it appears there is a leak in the water mains to her house, but inside her boundary and so her responsibility.

I gather the initial diagnosis was based on a rough check - their noticing flow to her house at a time in the morning when it could be expected no one was showering or the like. You could probably hear the water flow in the pipe.

She queried and was told they'll put a logger on the pipe to demonstrate more accurately that there is a leak and that's it's substantial.

a) Has anyone experience of this and whether the measurements are accurate

b) recommendations on how one detects underground leaks (assuming a check shows it's nothing above ground

Thanks..

Water is detected using a form of sonar which when used by a properly trained operator is accurate to within 1 foot of the actual leak.The old way was to use a ''listening stick'' which is accurate but requires an experienced ear,the modern way is by using a hand held sonar device which is also very accurate.As for finding the leak you can hire someone with this equipment to locate it for you or you can dig and trace the pipe til you find the leak.
The council or corporation usually have in house staff who do this type of work, but they should be able to give you contact details for private operators.

Get this sorted yourself asap. Water leaks underground can do substantial damage.

Dont get council to do this.
You may be able to hear the leak yourself on a quiet night, thro the stopcock hole, then start digging.
