Avoid Chemicals: Do not pour harsh chemicals into the system.
Water Conservation: Reduce the amount of wastewater your system has to process.
Protect the Drain Field: Avoid driving or building heavy structures over the drain field area.

Options include submersible, jet, and centrifugal pumps. Choose based on water needs and well depth.

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.
