Septic tank interior inspection:

Here we explain the importance of (and procedures for) inspecting the septic tank baffles and tank interior after septic tank pumping/cleaning. Cleaning the septic tank during tank pump-out can expose damage to the septic tank sides and bottom that cannot otherwise be found.

This septic tank pumpout article series provides a step by step, photo-illustrated guide to opening, pumping, and inspecting septic tanks, how a conventional septic tank is located, opened, pumped out, cleaned, and inspected.

This guideline is intended for septic pumping tank truck operators and as general information for homeowners or septic service companies concerned with septic system care.

Inspecting the Septic Tank Condition After Pumping

After septic tank pumping or perhaps better, after both pumping and wash-down, the empty septic tank is inspected for damage such as damaged or missing baffles, cracks, or holes. The right hand photo shows the septic tank intake baffle viewed from the cleanout port.

Warning: do not enter nor lean into the septic tank. We obtained this view using a remote digital camera to see the condition of the tank baffles. If the tank is cracked or the baffles missing or damaged, repairs may be needed.

Watch out: Do not enter the septic tank as doing so is likely to cause death by asphyxiation by methane gas in the tank. Even leaning over a septic tank, even one that has been pumped, is dangerous. You can be asphyxiated and fall in. Also, do not work alone.

Special breathing equipment and other safety measures are needed if a tank needs to be emptied.

Inspect the Cleaned-Out Septic Tank for These Problems

Evidence of cracks, settlement, or damaged tank baffles may be seen after pumping.

At this time the operator can also confirm the tank size. When a steel septic tank has been serviced by removing entire tank cover these conditions are seen easily.

But normally a septic tank is pumped by through a center port intended for tank cleaning. Some older concrete tanks which lack this port are pumped at the tank outlet opening but possibly at the inlet.

Septic pumpers can easily fabricate a tool combining a pole, mirror, and bright flashlight to inspect a tank interior.

We have had good success by inserting a digital camera into the tank and taking flash photos. Most of the photos in this article were obtained by that method.

If septic tank damage is found such as cracking, it may be possible to repair the septic tank by cleaning the surfaces and applying an appropriate masonry patching compound. But no one should enter the septic tank without proper equipment or preparation as there is a real danger of death by asphyxiation by the methane gas remaining in the tank.
