Flow-Thru, Worlds Freshest Water

Flexcon’s Flow-Thru well tanks, equipped with our patented Flow-Thru technology, diverts system water into, and more importantly out of the tank while the pump is running. This constant flushing action assures that the water in the tank remains as fresh as possible, eliminating the possibility of stagnant water. Water the video to learn more.

Flexcon’s Mixmaster Baffle Tank is the only composite, baffled retention tank on the market. It ensures uniform mixing and sufficient residence time to meet the contact time standard set by most health agencies in the United States and Canada. Watch the video to learn more.
