COMPATIBILITY & APPLICATIONS

System Integration & Use Cases

This Structural 16x65 pressure vessel is designed for residential and commercial water softening systems requiring a 4-inch NPT connection. The poly wound construction offers durability and corrosion resistance for mineral and resin bed applications. The included base provides stable floor mounting for installations where the tank will be filled with ion exchange resin, catalytic carbon, or specialized filtration media. Compatible with standard softener control valves and backwash systems using 4-inch threaded connections. Ideal for whole-house water softening, iron filtration, and multi-media tank applications requiring large media capacity.

💧 Pro Tip: Always verify your control valve threading matches the 4" NPT connection before installation. The included base is essential for larger vessels like this 16x65 model to prevent stress on plumbing connections and ensure long-term stability when filled with media.
