Here is what you need to know when buying a Best Garbage Disposal for Septic Systems

  • Always check your owner’s manual for the garbage disposal’s HP rating (how many watts it draws) and whether there is a switch that will turn it off while not in use. You do not want to overload your circuit or cause a fire.
  • Always select a continuous-feed disposal. The more blades, the more effective the action.
  • Look for a unit with a higher horsepower, because the higher that rating is, the more power is available for grinding.
  • Get a disposer with a sound-dampening system. This will reduce the noise.
  • Plan to put your garbage disposal in place virtually before you install it. You may need to move things around to make room for it.
  • Install the unit outside of your sink. This will protect the internal workings from splashing or spills.
  • Put your garbage disposal under a stable place that won’t wobble or vibrate, such as a countertop or kitchen cabinet.
  • Your disposer must be level and fitted securely.
