Hi All, I recently leased out a former restaurant. I did a walk through when the former restaurant was still in operation and saw standing water in the kitchen and stock room by the floor drain. I expressed my concerns with the Landlord and after a lot of give and take I finally got him to guarantee the plumbing for three months. Low and behold the grease trap has issues, and the plumbing is not functioning properly even after having the drain cleaned. Also, there are issues with the grease trap the city told us we will have to replace it and possibly dig and replace piping. The landlord now tells me that all the issues stem from the grease trap therefore he is not liable. A simple Wikipedia search states that the grease trap is a plumbing device. He told me grease is not plumbing. The bills are racking up and from what I see my only recourse is to sue the Landlord. I brought this all up to him and he told me that he will try to get the former tenant to fix the issues. He will not pay no matter what and he expects his rent. I have not been able to sleep more than an hour or two all this week. Just looking for some opinions. Thanks.
