Garbage Disposal Maintenance

Most garbage disposals are robust kitchen appliances that work for years with little or no maintenance. However, a jammed, clogged, or otherwise malfunctioning garbage disposal can mean calling your plumber for garbage disposal repairs.  There are  a few things you can do to keep your garbage disposal working great and avoid that expensive repair call.

First, you should always run cold water down the drain into the disposal while the unit is grinding and for five to ten seconds after you turn it off.  Running water helps flush the ground material down the drain and through the drain lines.

Cold water is better than hot water because it will help fats and oils congeal so they can be flushed away.  Hot water will cause fats and oils to liquefy and they can end up lining the walls of your drain line which will eventually lead to a clog.

Avoid putting high fiber waste material like corn husks or celery stalks down the disposal.  These can clog even a heavy duty waste disposal.  Don’t overwork a light duty disposal by putting bones down it or running it continuously for more than a few minutes.  Small disposals are not designed to handle these types of loads.

Never put glass, metal, plastic, or any other non-food material down the disposal.  Not only can it be dangerous, but these materials will jam or completely ruin the disposal.  Finally, you can help rid the disposal of food deposits and odors by grinding egg shells or small amounts of ice.  Your disposal will work better, smell cleaner, and last longer.

Septic Garbage Disposals

There are a wide range of opinions about using a garbage disposal if you are on a septic system.  These opinions range from those who maintain that garbage disposals should never be used on a septic system to those who believe that garbage disposals actually help septic systems work properly.

It can be a challenge to make sense of these conflicting opinions, but EPA research indicates that garbage disposals place an additional burden on septic systems.  The best answer is probably that most properly sized and maintained septic systems can handle this extra load imposed by use of garbage disposals, especially if the homeowner has the septic tank inspected regularly and pumped when needed. About a quarter of the 27 million residential septic systems in use in the United States have garbage disposals and there is no empirical data that shows a significantly higher rate of septic system failure with these systems.

Not surprisingly, most garbage disposal manufacturers take the position that garbage disposals do not harm septic systems.  In fact, some disposal manufacturers market garbage disposal models specifically designed for use on septic systems.  These disposals work just like conventional garbage disposals except that they have a cartridge attached that injects natural microorganisms into the drain whenever waste is ground.

These microorganisms help break down the food waste and reduce the level of solid material in the septic tank.  Other than having to replace the cartridge every few months, these special septic models don’t require any additional maintenance or care than a conventional model.  A reputable plumber who handles kitchen repairs can help you choose and install a great new garbage disposal.
