Septic inspections: what to expect
The EPA recommends that the average household septic system be inspected at least every three years by a septic service professional, and alternative systems with mechanical parts about once a year [1].
What the provider should do
According to EPA, a provider should inspect for leaks and examine the scum and sludge layers in the tank. The service report should note any repairs completed and the condition of the tank. If other repairs are recommended, EPA advises hiring a repair person soon [1].

Questions to ask
- Will you measure and record the sludge and scum levels?
- Will you check the outlet baffle and effluent filter?
- Is the drainfield checked, and how?
