Customers.Garbage disposal was slowly leaking from bottom, causing very mild damage to the cabinet flooring below. Customer agreed to have the garbage disposal replaced as well. Wanted to have their undermount sink, caulked around the perimeter. We were uninstalled the old garbage disposal and installed a new one. Afterwards ran white silicon, caulking around the perimeter of the sink and cleaned up. Tested garbage disposal by filling up the sink and allowing it to drain. No leaks. While on site notified the customer that their pressure is slightly elevated and their water.Heater is approaching ten years old. Thermal expansion tank was still decent.However, I gave them a quote to replace thermal expansion tank and p r v as well as a quote to replace water.Heater and p r v. Thank you for choosing and trusting t e with your plumbing needs
