Well the precise correct answer depends uppon a read of the policy. If the policy is clear that the sewer endorsement adding a peril had a different limit of liability than the balance of the coverage, then there could be an issue for obtaining the exta coverage you seek. However, it depends on the wording also of the habitability coverage and its wording. Unable to answer definitively without sight of the policy.
