You should pump your septic tank once every two to four years for a family of four, depending on your septic tank size. You should pump a 1,000-gallon septic tank every two years, while a 1,500-gallon tank should be pumped every four years. Water usage also affects how often you should pump your septic tank. If you notice slow drains, foul smells, or gurgling sounds from your drains, you should pump your septic tank as soon as possible.

The cost to pump a septic tank is $400 on average for most homeowners. You could spend as low as $250 if you have a smaller septic tank or as much as $600 or more if your tank is 1,750 gallons. 

The size of your septic tank is the primary determining price factor, but your geographic location can also play a part in your overall cost. For example, pumping a septic tank in Minneapolis, Minnesota, costs between $175 and $275 on average, but in Portland, Oregon, you'll spend between $440 and $750.

If you’re using it as a preventative measure, say in the event that you frequently experience clogs, once every one or two years or so is a good time frame. The number of times will depend, though, on how old your plumbing is and how prone it is to clogging.

While the lifespan of your septic system will depend on a variety of factors, including how well you keep up with regular inspections and maintenance, it will eventually need replacement. Most septic tanks can last between 20 and 30 years, and under good circumstances, a septic drainage field may last up to 50. On average, though, about every 30 years or so, a major septic renovation will be necessary.
