Tenant complained that toilet wasn't flushing. I evaluated the septic tank and all was well. I referred the tenant to contact a plumber and manage a possible clog. Long story short, the plumber came in on a weekend and accidentally broke appliances trying to snake the tenants drains. So he had to pay for some of his mistakes. After a few days of repair and evaluation the major issue was that the tenants sewer pipe stub up from the toilet going under ground several feet was crushed. It was old black PVC pipe that was probably used as a stub up 20 yrs ago. Our guidelines state that we are responsible for the utilities up to the mobile. The tenant asked the contractor to proceed with the repairs without consulting with us and now he's expecting that we will help him pay for this bill. We would have fixed this problem ourselves if we had been notified but he cleared the contractor without discussing anything with us & now he expects us to foot some of the bill. This specific contractor is known for large labor bills, & we feel that we should have been consulted. How would this best be dealt with??
