This job we went to lead detection services for homeowner on right side of yard just off the side of the home above the penetration for the Water-main service though the homeowner does have a swimming pool and is not aware if the swimming pool tease off the main line to fill or not he said he only fills it when it gets a little bit low with his water hose and he has never completely drained the poo. there Were also a lot of othernuances to contend with such as a French train that runs along the side of the house. All the power runs right along the side of the house and there is a swimming pool pump that was running. We narrowed down the location of the leak to the best of our ability at approximately 15 to 24 inches off the side of the home where the waterline penetrates the slab we marked the area with flags for the tech.
