Challenger "I" Series Well Tanks

The super durable, high-end Challenger "I" series water tank delivers CAD2 technology (Flexcon's famous controlled action diaphragm system) at a very affordable price. In short, you get superior air and water separation and unmatched performance. Our patented manufacturing technique allows Flexcon to properly size the diaphragm in a full range of sizes from 14 to 119 gallons.  Every challenger tank undergoes a seam-weld test, high-pressure test, and is subjected to a helium test for air leaks. Before leaving the factory, a final air check ensures each tank arrives at the job site with the correct pre-charge. This tank has become an industry leader. Flexcon stands behind every Challenger tank with a five-year warranty. Just what you would expect from Flexcon: quality and performance, guaranteed!
