Is it ok to reinstall a garbage disposal that has been sitting unused for a year?

<p>I have a garbage disposal that has been sitting in my garage unused for a year. It was removed during a kitchen remodel and the contractor insisted upon installing a new one. The reason stated was the original was sitting usused for a month or so and the contractor&#039;s plumber indicated that he had seen lots of garbage disposals fail in those situations.</p> <p>Ironically, the new disposal he installed has started leaking, with both the washer and the putty around the strainer pretty degraded. I don&#039;t know if that&#039;s why it case loose, or because of the vibration from operation.</p> <p>Anyway, I need to reinstall the disposal and I am wondering if it is better to install my original one. It is a higher end model with several years of warranty left over. However, it has been sitting dry in my garage for more than a year.</p> <p>Is there a high chance of failure if I reinstall that disposal? Is there anything I can do to prevent that or to reduce the risk?</p> <p>Thanks,</p> <p>Deepak</p>
