A lessor leased a trailer park to a tenant. At the time, sewage was disposed of by a septic tank system that was not connected with the public sewage system. The tenant knew this, and the lease declared that the tenant had examined the premises and that the landlord made no representation or guarantee as to the condition of the premises. Sometime thereafter, the septic tank system stopped working properly, and the county health department notified the tenant that he was required to connect the septic tank system with the public sewage system or else the department would close the trailer park. The tenant did not want to pay the additional cost involved in connecting with the public system. The tenant claimed that he was released from the lease and was entitled to a refund of the deposit that he had made. Was he correct? [Glen R. Sewell Street Metal v Loverde, 451 P2d 721 (Cal App)]
