Customer had a toilet leaking from the base. I left options to replace or just pull and reset. They opted for replacement. After getting signatures I went and purchased a new toilet. Upon pulling the old toilet I noticed two things. Flange was too low, and water was holding inside the drain. I went into the crawlspace to inspect the plumbing. The line for the toilet was extremely back pitched. Due to the previous drain install for the master bathroom, the only solution is to repipe the drain line for the master bath room. Left estimates for that work. When I went to turn water back on to the home I noticed a wet spot in the yard. I let customer know about service leak and that the main valve and prv were in really back condition. Presented the option to fix and customer agreed. I will be sending estimates for a whole home water repipe and a new water service.
