One of the hardest products on your septic tank is grease. Grease can easily be introduced to your tank by pouring leftover grease down the drain when cooking and when using a garbage disposal. The best way to stop grease is to not pour it down the drain in the first place. However, a grease trap and special enzymes are also helpful when keeping your septic tank clear of grease.
The Worst Sources Of Grease
Grease comes from various food products, including meats, cooking oils, lard, butter, shortening, sauces and baked goods. Rather than stopping grease, a garbage disposal simply breaks the grease up and allows it to reach the septic tank. Given that grease is lighter than water, it floats on the top. It can also combine with the solids, toilet paper, and soap residue to form a hard crust. This then flows into the drain field, where it will then cause the septic tank to back up.
How Enzymes Can Help
Enzymes added to a septic tank attack the grease by destroying the connections between its individual molecules. Once this happens, the molecules will have no way to join together and form grease deposits. Enzymes will not eliminate all of the grease, though they can eliminate enough to make a difference. However much the enzymes eliminate depends on the temperature and pH. The enzymes can be added by simply pouring them down the drain or toilet.
When You Should Get A Grease Trap
Grease traps are usually not used in homes because the average household does not produce enough grease to justify one. However, if you like to fry donuts or if your cooking habits lead to you pouring a lot of grease down the drain, the grease wouldn’t be mixed well enough with dish detergent to mitigate the risk. A home will usually need the smallest grease trap available. Grease traps are installed either under the sink or outside the home.
How To Install The Trap
How the grease trap is installed depends on the particular model. There are usually three connections, with one connection attached to the holding tank vent, one connected to the sink that will be the source of the grease and one connected to the pipe that travels to the septic tank. The last connection is on the lower right of the grease trap. Even if you have a grease trap, make sure that you do not flush solids down the drain. Click here for more information.
