The tech that was sent, think his name was Mike, to correct the issues we were having did an excellent job. The separator is functioning perfectly. The shop employees have been instructed to verify any person who accesses our separator is from your company in the future. The only explanation of the condition of the separator that resulted in you having to come out last was either incorrect pumping of the separator the last time you were out or someone pumped waste water into our tanks without our knowledge. Someone had to physically open the separator dump waste water into it for there to be fuel inside the clean water chamber, all other scenarios are impossible. Either way, Mike now has the system running as it should and we appreciate the quick response. Thanks again for a job well done.
