Pinpointed the leak on 2 mains

Lds done exactly what they promised turned up on time and pinpointed the leak on 2 mains water within 1 half hours. Engineer stayed on site until excavated to ensure leak detection was accurate. On a 24 metre length of mains water detection was within 200 mm of leak saved me a lot of time and money as the location was on a private road that had just been topped out.
