After reading 5 star reviews, I selected Action Septic Pro LLC for doing preventive maintenance. Oil stains and septic sludge on driveway, a quote of $1,200 which I refused, 5 hours late were not big issues for me because I could handle them. But I'm very disappointed today after finding out what they did.
A real technician from other professional septic service company opened the septic tank again to repair the outlet tee. We found what they had done. Action Septic Pro had pumped out only 1/3 of sludge including all water. 2/3 of sludge was still in the tank. We were very surprised and saddened to see the sludge. But he had the tee replaced in 20 minutes and I could save a thousand dollar.
Customers, be careful when you give 5 stars. You probably never checked the inside of the tank if they really pumped the tank all or not.
Edit: They answered "All of our customers see what is going on before, during, and after the job to guarantee their satisfaction.", which is not true. Customers can easily be satisfied because they don't know about the system. I was the one that found the truth done by your employees.
