Customer reports a slab leak in master bedroom. It is very difficult to perform leak detection on potable water system without having access to all 4 units that are connected to the same meter. Will need to have access to all 4 units in order to make sure there is no other water running while performing leak detection. Quote is $450.00 for the first hour of leak detection and $195.00 for every hour after. Most leaks are able to be found within 2-3 hours.
