I have been asked to evaluate a cesspool. Does anyone have experience with these? or ideas for proper evaluations?

and I really am a member of NACHI, however I am not able to log on as a member for some reason

Many states and jurisdictions require a license or certification to inspect a cesspool. Even if your state does not, I would defer the inspection to a cesspool contractor if you are untrained in this type of inspection.

Thanks. I do have training on septic systems and have had training coverage on cesspools, but I have never actually inspected a cesspool. Quite a few septic systems, and they’re certainly more complex than a cesspool. I just wondered about any idiosyncraticies.
