The short answer

Underground Leaks Explained

An underground or slab leak is a water leak in pipework buried in the ground or beneath a concrete slab. The Plumbing Gang’s licensed plumbers use water meter tests, pressure testing, acoustic sounders and thermal imaging to find the leak, then explain repair options with fixed-price choices before work starts.

I am a disabled guy and Reegan attended my home at short notice to fix my blocked toilet plumbing. Reegans professionalism was amazing. He explained in full what the issue was and what he was doing as he did it. The work conducted was done in a professional manner and thoroughly checked it was working properly before he departed. Great guy and wonderful work ethic. I highly recommend these guys for any plumbing issues without any hesitation.
