If anyone ever needs septic system help these are the people to call. We had a recent septic emergency. A company we had used before pumped the tank. Within 3 days tank was full again. The "X" company we had used to pump tank told us drain field needed replaced, an 8K-16K expense. A friend suggested we call Dave at American On Site to get a second opinion. What a different story, he confirmed that our drain fields were fine and within a short time had men out that cleared the blockage to drain field and did a simple repair on septic tank. Total bill was extremely reasonable. I never do reviews, but for Dave I needed to take the time as he kept us from emptying our bank account for repairs not needed.
