underground slow leak in home

kavanaa1

Hi

For the last 4-5 weeks theres been water/damp lines slowly progressing up some walls dividing an en suite and main bathroom. We had a specialist in today to try locate the source but werent successful. He believes its coming from the copper pipes in the mains system feeding the toilets & sinks, not the heating system.

Has anyone any advice on how to pinpoint the source of the leak?

I see some things on thermal imaging and fluoescent dyes online, but would like to see if anyone has any experience with these prior to proceeding.

Thanks in advance

3 years ago I had same problem,spent 3 days digging holes ,dust ,noise,wife went mad .
In end ran new flexible pipes overground . Cut your loss and put in new pipes.

If you post pictures we might be able to advise.

Outside that you might need to trace your pipes. Its not that hard to actually do, If they are metal you can do it with a stud detector if they are pex you can do it with persesistance.

we had a leak from a central heating pipe under a concrete floor last year and got a guy with a listening device in & he was able to pinpoint leak.

Hi
We had a slow leak and got it fixed last week - hence Im trying to replace tiles. The plumber who found it had a machine to check pressure in radiators so he was able to isolate it and found it fairly quickly. He also put his head to the floor and dug where the sound was loudest - this was the best method and most effective. When he opened up the floor there was virtually a fountain of water coming out. There wasn’t much moisture visible at the site of the leak and the water had travelled into 2 bedrooms. Even with what appears to be a slow leak there can be a lot of damage going on under ground.

What you need is someone to isolate areas of the house and check water pressure on heating system and mains and also put your head to the ground and listed. This method worked for us. Good luck – a leak is very stressful.
