Maintaining septic systems
January 11, 2011
Is this question fact or fiction? “It’s not necessary to pump a septic system if you are careful with what goes down the drain.” False.
To maintain a well-functioning septic system, it must be pumped every two to eight years depending on use and size of the tank. It is also necessary to keep the bacteria that live within the septic tank healthy and decomposing waste efficiently.
To do this avoid products with the following warnings on the labels: “Harmful if swallowed,” “Avoid contact with skin,” “Do not get in open cuts or sores” or “If product comes in contact with eyes, call a physician immediately.” However, do not pump too frequently because it can reduce bacterial populations and is costly and unnecessary.
Under normal circumstances, there is no reason to put additives into the septic system that say they increase bacterial functioning. Also, ignore the myth about dumping yeast into a septic system to maintain it, as yeast is not active in a septic tank. There is no substitute for pumping.
Things that cause a system to fail:
blocked or broken pipes or lines between the house and tank or tank and leach field
Recommended Stories For You
pump failure on systems with pumps
tank blocked with solids, collapsed or leaking
flooded drain field or one with poorly draining soil
drain field clogged with solids or roots
extensive use of the garbage disposal
use of salts and chemicals from water softeners and washing machines
pouring kitchen grease into drains.
Tips to keep a septic system working well:
Don’t water the leach field
Don’t flood the system with excess water
Keep excess solids out of the system
Avoid flushing toxic chemicals down the drain
Avoid using the garbage disposal
Regularly pump out the septic tank and have the physical components of the system inspected
Don’t drive or park over the leach field.
Never dump kitty litter down the toilet because it clogs lines and systems. Don’t put women’s sanitary products or Kleenex down the toilet. Never flush cigarette butts or other inorganic materials that won’t break down in the tank down the toilet. Only toilet paper and your body wastes should be flushed.
