  1. Pump your septic every Two Years. Insist that the pumper clean your septic through the manhole on top of your septic tank, rather than the 4 inch inspection pipe which sticks up through your lawn.
  2. If you use a Garbage Disposal, pump your tank Every Year. Or, better yet, compost your kitchen scraps.
  3. Keep kitchen Grease out of your septic system. It is not broken down easily by your system and can clog your drain field.
  4. Space out Laundry Loads over the course of the Week and wash only Full Loads. The average load of laundry uses 47 gallons of water. One load per day rather than 7 loads on Saturday makes a big difference to your septic system.
  5. Install Low usage Water Fixtures. By installing low water usage Showerheads (2.5 gallons/minute), Toilets (1.6 gallons), Dishwashers (5.3 gallons) and Washing machines (14 gallons) an average family can reduce the amount of water entering the septic system by 20,000 gallons per year! Low flow showerheads and toilets can be purchased at local lumberyards. Water saving dishwashers and washing machine can be purchased at better appliance stores (ask for ASKO brand washers and dishwashers).
  6. Set your Watersoftner to Recharge as Infrequently as comfortable.
  7. Use Liquid Laundry Detergent. Powered laundry detergents use clay as a "carrier." This clay can plug the drainfield. The use of Sudsavers is highly recommended.
  8. Minimize the amount of Household Cleaners (bleach, harsh cleaners) entering the septic system. Pump your septic every 6 to 12 months if you do lots of painting or staining.
  9. Do not use Automatic Toilet Bowl Cleaners, such as "2,000 Flushes." The continuous slow release of these chemicals into the septic system kills the micro-organisms which treat your waste water.
  10. You do not need to put Special Additives into your septic system.

The average life of a septic system is 25 to 40 years. By following the above tips you will extend the life of your system.
