Co-founders Gary Koteskey, Gene Brooks and Arnold Koteskey, had been installers and site consultants for twenty years prior to starting Sim/Tech Filter.  The frequency with which they were digging up and replacing fields on newly engineered systems was on the increase.  Aware that pressure systems and new technology were the wave of the future they realized that something had to be done.  Not wanting to be left behind, they started to research the ever abundant failing pressure systems.  What they found seems very evident and obvious now, but eluded the industry for years.  Pressure systems have smaller discharge holes than the more traditional gravity systems.  Cucumber and tomato seeds, lint, debris and biological slough from the system itself, are all capable of plugging a pressure system.  It takes only a tablespoon of contaminates to close half the holes in a standard pressure system.  Septic tank filters work well for gravity systems with larger holes but they do not stop all of the smaller material that can plug a pressure system.  Why were no filters engineered into pressure systems?  There were none.  Safe guarding components were not used or available for the new pressure type systems.  This laid the foundation for Sim/Tech.  After years of research, development, and testing SIM/TECH developed and manufactured the industry's first pressure system filter, the STF-100 and Sim/Tech Filter was started in 1998.
