Septic System Don'ts

  • Don't overload the septic system with high volumes of water.
  • Don't connect basement sump pumps to the on-site septic system.
  • Don't connect backwash from water treatment devices directly to the on-site septic system without professional advice.
  • Don't use a garbage disposal. Chopped up food particles do not break down in the septic tank and can make their way out into your leach field lines causing clogs.
  • Don't allow large amounts of fats, chemicals, or solvents to enter the septic system; don't allow any plastics to enter.
  • Don't enter a septic tank without proper ventilation. A second person is required to be present above ground and other requirements by law are met for confined spaces. Sewer gases can be fatal.
  • Don't allow vehicles or heavy equipment to drive over or park on the leach field. This may compact the soil and crush the piping.
  • Don't plant anything over the leach field except grass. Especially do not cover the septic tank or leach field with asphalt or concrete or other impermeable material.
  • Don't put in a separate pipe to carry wash waters to a side ditch or woods. These "greywaters" also contain disease- carrying organisms.
  • Above all else- DON'T wait for signs of failure. Check the septic system regularly.

Do Not Flush

The best thing to do for your septic system is to be sure not to flush anything other than human waste and toilet paper (preferably 1 ply toilet paper).

Even if items are marked as "septic safe" do not flush them. For example, some baby wipes and cat litter may be labeled this way. It is not good for your septic system to flush anything other than human waste and toilet paper because it does not break down in the septic system correctly.

Odors coming from outside the house can be an indication that your septic system is overfull and you need septic pumping service. A vent pipe may also be installed to help release odors from the septic system.

Sometimes when drains are not used the noxious gases can build up and cause odors. For example, if you have a shower downstairs that gets little use you may notice that at times there is an odor coming from that area. Running the water regularly in those drains will help keep odors at bay.
