A new noise, any leak, and certainly failure to start, can signal the need for a new disposer. However, these devices of convenience (sometimes called a disposal or disposall), are not always ready for the scrap heap when you hit the switch and nothing happens. Hard material of any kind can become wedged inside between a blade and the casing and prevent the disposer wheel from turning. Removing the offending material is sometimes all that is needed to get it running again–but this fix should not be attempted unless one is absolutely sure of how to perform the removal without injury. If in any doubt–employ a licensed plumber. If the hard material turns out to be part of a blade–game over–it’s time for a new disposer.
