The average cost to pump a septic tank ranges between $225 and $600. Septic tank inspections range from $150–$450. Depending on the type of repair, you can expect to pay $600–$3,000.

In general, a septic tank should be inspected every 1 to 3 years and pumped every 3 to 5 years. The frequency of pumping the septic tank depends on the tank size, number of people in the household, habits of water use as well as the amount of solids accumulated in the tank.

Household septic tanks are typically pumped every three to five years. Alternative systems with electrical float switches, pumps, or mechanical components should be inspected more often, generally once a year. A service contract is important since alternative systems have mechanized parts.

Septic cleaning is similar to septic pumping, but with one key difference. Whereas septic pumping deals with sucking out solid and sludges floating on the top of the tank, septic cleaning happens when you drain all of the water and clean out everything stuck to the bottom of the tank.
