Customer had a leak coming from third floor bathroom when they were gone for 17 days. Upon seeing water marks coming from toilet flange on cut open ceiling, and removing the toilet and seeing the wax ring not fully attached, it was determined it came from the toilet. Noticed that the flapper was smaller and water kept on continuously running, and it kept running while they were gone which it was caused the leak along with the wax ring. Performed a major rebuild and changed wax ring. 2yr warranty on parts and labor.
