Frequently Asked Questions

What does a septic inspection include?

A thorough septic inspection includes locating and uncovering the tank, pumping it to inspect the interior, checking inlet and outlet baffles, measuring scum and sludge layers, evaluating the drain field for signs of failure, and testing system flow. The inspector provides a written report.

Is a septic inspection required when selling a home in Pennsylvania?

While there's no statewide mandate, many Pennsylvania municipalities and counties require septic inspections during property transfers. Even where not legally required, most buyers' lenders will require an inspection. It's wise to get one before listing your home.

How much does a septic inspection cost in Pennsylvania?

A basic septic inspection in Pennsylvania costs $300 to $600. This typically includes pumping the tank. More comprehensive inspections that include dye testing or camera inspection of lines may cost $500 to $900.

Who can perform a septic inspection in Pennsylvania?

In Pennsylvania, septic inspections for property transfers should be performed by the local Sewage Enforcement Officer (SEO) or a qualified inspector approved by the municipality. For routine maintenance inspections, licensed septic service companies can evaluate your system.
