Standing water in HOA sewer Main

[Murlie Keller]

My nightmare began when a recent tenant failed to notify me of water damage. I discovered wet moldy carpet in the basement. Subsequent scoping of the main line (and multitudinous other testing) revealed 17 feet of standing water in the main sewer line underneath my property extending under the adjoining property. The HOA claims they deal with standing water in the main sewer line by bi-annual snaking of the line. They have no written record of having done this "maintenance", and even stated that my tenant refused to let them in to do it. They have never notified me of any such "maintenance in the 8 years I have owned the property. How can I get the HOA to properly fix (dig up and replace) that part of the sewer line?
