Knox Septic Service

We are selling our home. After a suspicious dye test on the septic system, septic inspections were scheduled. Company owner came to property somewhere around 4pm. Boyfriend/homeowner and buyer were also in attendance. I was inside in the room adjacent to septic access. I heard company owner say total septic system failure and it would cost 15k - 25k to replace. Boyfriend came inside and proceeded to tell me the company owner stuck a probe into the ground one time, pulled the probe out, then stated total septic system failure and it would cost 15k - 25k to replace. He determined this after the largest 2 day rainfall we have had this year with a septic tank that was full and scheduled to be pumped and without doing an actual inspection. The following day a different company came, probed the ground repeatedly marking the entire drainfield as well as the distribution box location, and viewing the hole where the septic access had been unearthed. Their report came back with no deficiencies and not suggesting any repairs. This was also before the tank had been pumped.
