Disposers are low maintenance systems, but inundating disposers with hard food matter and misuse can lead to significant problems.
Although disposers require minimal maintenance, proper use will lengthen the system's service life.
There are a number of factors to consider in the use and maintenance of disposers.
Although disposers will grind almost anything, certain waste, such as oyster shells, can build up in the drain line and shouldn't be regularly disposed of in these systems. Also, high concentrations of fibrous materials, such as corn husks, can potentially cause clogs over a period of time.
It's important to keep in mind that a disposer does not replace a dumpster and should never be used with dry waste.
