Septic Tanks questions, answered by experts

A septic tank should be emptied approximately once every three to five years, though this frequency will vary depending on your water usage, the size of your tank, how many people are in your home, and other factors. A maintenance plan for your septic system may be useful for professional emptying and inspection of other important parts.

Good news: You’ll naturally increase the bacteria in your septic tank simply by using it. If you want to encourage more good bacteria growth, stop using products and household cleaners that kill bacteria, such as bleach and harsh chemicals. Never flush antibiotics, and make sure only water and waste go down the tube—not paper products, feminine hygiene products, or diapers.

A mound septic system, when properly maintained, can last between 20 and 25 years on average—though some last longer or malfunction sooner than that. The most important part of maintenance is getting an annual inspection of the vital parts of the system to ensure they’re in proper working order and not too backed up with sewage.

The precharged pressure tank should start at around 28 psi. The two pressure settings of note are the cut-in and cut-out pressure. The well pump starts when the tank reaches the minimum cut-in pressure. It turns off when the tank reaches the maximum cut-out pressure. The desired water pressure in the household is usually a few psi above the cut-in number. The difference between the cut-in and cut-out pressure settings should be 20 psi. Typical settings for household applications include 20/40, 30/50, and 40/60.

Provided your system is not damaged and you’re using it properly, a septic tank only needs to be pumped every three to five years. Find out who pumps septic tanks in your area, because this is not the kind of job you can DIY. Attempting to do so can put your health and that of your system at risk.
