There are a number of different signs that indicate a need for septic tank pumping services, including:
A household septic tank typically needs to be pumped every three to five years. However, alternative systems with mechanical components, pumps, or electrical float switches need to be inspected more often, usually once every year.
It typically costs from $400 to $750 to have a septic tank pumped, with the average being around $550. For extremely large tanks, the cost can be $1,000 or more. The average cost of an inspection is close to $300.
Bacteria living in the septic tank break down solids and organic matter into less complex compounds, but only a small percentage of solids are decomposed or flow out with wastewater and instead remain in the tank. Over time, the solids that are not broken down will begin to accumulate and fill the tank. Once the tank is full and cannot hold any more solids, those solids will start to flow out of the tank, This may lead to clogged pipes and soil absorption.
