Septic Tanks questions, answered by experts

Needing to pump the tank as soon as it “looks” full is a common myth about septic systems, as wastewater will eventually drain into the leach field. Instead, it’s better to determine how many solids have accumulated. A septic maintenance technician near you can test this to find out whether pumping is necessary.

With proper maintenance, most types of septic systems—including mound, evapotranspiration, and constructed wetland systems—can last up to 40 years. To keep your system running as long as possible, follow basic septic tank upkeep guidelines, like pumping your septic tank every three to five years and only flushing human waste and toilet paper.

The depth of your septic tank has nothing to do with its size. In fact, some septic tanks can even be installed above-ground! Like other sizes, a 1,000-gallon septic tank could be buried as shallow as 4 inches below the ground or as deep as 4 feet. It all depends on your specific property.

Yes, you can adjust your well pump pressure relatively easily by yourself. You’ll need to remove the cover from your pressure switch and adjust a nut that controls cut-in pressure. Learn more about how to adjust a well pump pressure switch with a step-by-step guide to setting your water pressure.

Septic tanks appear full after pumping because the liquid levels have returned to normal. If you can see the pipe, the tank is empty. However, heavy rain can cause septic tanks to fill faster than normal. You might also have leaky pipes or faucets, causing extra water to drip down the drains and into the septic tank.
