Septic Tanks questions, answered by experts

Saving money on property taxes and having direct control over your waste system are both pros when buying a house with a septic tank. However, it’s easier on the house and the yard if a home can be hooked up to a municipal system, which is why septic tanks are best for homes where that isn’t an option. Expensive repairs, potential odor issues, and regular maintenance are all cons of septic systems. 

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.

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.

Most septic tanks need to be emptied every 3 to 5 years, but it’s a good idea to monitor the fill levels of your septic tank all the time. You can do this by installing a pressure level sensor to detect the internal tank pressure, or by having a septic tank company perform an annual inspection to let you know when you’ll need to pump the tank.
