The 34.34-gallon PressureWave tank is a premium-quality, industrial-strength pressurized well tank used by top pump companies and installers around the world. The water chamber is constructed of a virgin polypropylene liner and an FDA-compliant, high-grade butyl diaphragm which does not impart any taste or odor to your drinking water and keeps the water contaminant-free. The O-ring-sealed air valve and cap and our stainless-steel patented water connection ensures no air leakage. The corrosion-free, rugged composite base and rust-resistant exterior paint finish add to the tank’s longevity. This is a maintenance-free, pre-charged pressure tank certified to NSF/ANSI/CAN standards 61 and 372, which is backed by a five-year warranty and can be a direct replacement for most installations.
