Thanks for introducing us to the DrainboÂ® System. We had frequent sewage back-ups at the airport. Grease from the restaurants in our terminals was clogging sewer lines and needed to be flushed every three months. Since installing the DrainboÂ® System, we no longer have a problem. That stuff really works! I highly recommend it to anyone having a problem with grease build-up in their waste lines.
