Today we came out to help the customer with an issue of the sound of running water in her home. This sound is located in the downstairs bathroom in in in near the shower. I took apart the shower handle to look inside the wall in the drywall in frame are completely dry so is the pipe but the sound increases as I took a shower handle off the mixing valve is making a lot of noise which tells me water is running through the mixing valve we could also see water running through the meter so we know somethings leaking on the house because all the fixtures are shut off. I gave the customer the number to a leak detection company locally they should be out Thursday to identify the week for her customer will call us back if she wants us to do the repair. She also signed up for a membership today and I gave her a zero charge service of swapping out her washing machine hoses.Customer seem to be happy and satisfied with the job performed we look forward to servicing them in the future.
