I took the National Association of Wastewater Transporters course and all it did was convince me that there are too many systems types, qualities, installed by idiots, wrong type in the wrong place, components are all hidden underground… too much liability. I found a couple of qualified guys nearby to do it and all they do is septic systems.
Too much liability and bad news can be real bad. Let someone else tell 'em the septic system’s shot and there’s no other place on the property to put a new one.
$225’s not worth it.
