8500 TwinFlo
The replacement of Fleck's 8500/TwinFlo 100E Control Valve with the 9100 Twin Tank Control Valve will be effective July 6, 2010. The 9100 Control is a high-performing, competitively-priced alternative, with more options and functional capabilities than the 8500 model. Pentair Water will continue to offer Fleck 8500 Control Valve service parts for the next five years to support installed systems in the field. SEE > Replacement Valve FAQ Article.
