Myth No.8: I had a septic inspection company offer a really great price to inspect from the house to the tank. We hired "them" and "they" said the system was working fine.
What's most important is how the liquids drain from the tank. If the plumbing from the house is graded right, all things will drain to the tank.
I've heard the horror stories of folks who have purchased a home, said they had an inspection from the house to the tank and everything looked fine. 3 weeks after moving in, they're having a septic backup.
What the homeowner didn't know was the inspector didn't do a CCTV inspection of the outlet pipe to the field. It's the equivalent to doing half the job.
The several cases communicated to me were all situations where the outlet from the tank to the field were not inspected.
This leads to an expensive repair for a new homeowner! Keep in mind, a new system can cost upwards of $25,000 depending on the installer.
We insist on the "FULL" septic inspection, not just a partial inspection. After all, the rule is "shit runs downhill".
