What Does It Mean If You Have Full Septic Tank?

What does it meant to have a full septic tank? Could this cause issues to your system and property?

Septic tanks, in general, stay filled to their normal liquid level, which is between 8 and 12 inches from the top of the tank. If the liquid level goes above the outlet pipe, or approaches the top of the tank, then it’s considered “overfull.” So it’s better to think in terms of an “overfull” tank than a full one, because full is fine while overfull can be bad.

Tanks tend to be overfull when there’s a problem with the absorption area (lateral field). It’s also likely that there could be a plumbing problem.

If you have a cleanout, that’s located between your house and your tank, you can look to see if there’s any backup in that cleanout. If you don’t find any sewage backup there, then it’s likely that wastewater isn’t making it to the cleanout and you have an indoor plumbing problem. If there is backup at the cleanout, you might have a septic system problem.

Generally, septic tanks should stay at their normal liquid level, with effluent entering the nearby absorption area. Once in awhile, for whatever reason, an absorption area may not be accepting wastewater like it should. When this happens, the tank ends up in overfull mode, and while pumping out the tank may help, there’s usually more work to be done to fix the problem.

Cat Cans Portable Services recommends routinely pumping out your system, while also limiting grease discharge and the use of garbage disposals. Also, never flush acids, polishes, oil, paint or grease down your drains; using biodegradable products is best.
