40 Gallon RO Water Storage Tank for Commercial RO Systems

Flexwave Composite Pressurized RO Tank

Flexwave RO 40 Gallon Water Storage Tanks use a butyl rubber diaphragm to store and deliver reverse osmosis water using air pressure within the tank.

Flexwave light commercial and residential RO composite storage vessels offer high strength, precision molded internal liner reinforced w/ continuous strand fiberglass and sealed w/ high grade epoxy resin. Flexwave RO tanks are designed with oversized copolymer polypropylene lower water chamber with 100% butyl rubber diaphragm. Lightweight, non-corrosive construction for maximum life and maximum flexibility.

Flexwave composite tanks flaunt a seamless polypropylene liner that eliminates top and bottom leak issues, as well as stainless steel reinforcing rings that back up all threaded openings. Injection molded domes increase shape consistency and strength while wetted surfaces made of high quality polypropylene add zero taste or odor.

Flexwave FWRO40 can be used as a direct replacement for ROMATE40, which we have discontinued.

FLexwave RO Stroage Tanks are Quality Tested and Certified:

  • Made in USA
  • Certified to WQA-NSF/ANSI 61 and WQA-NSF/ANSI 372
  • All Flexwave tanks are 100% pressure tested and carry a 5 year limited warranty.

Enables the person to move around while wearing.
These silicon socks look a bit odd at first glance but they work great and best of all, any lotions and oily creams are contained on the inside so you can walk around. They are very soft. I haven't had them long so I can't comment on durability, but they are not made of lightweight material.

Does the job but dangerous to walk with!
Does the job but dangerous to walk with: foot is sliding inside the sock if the foot was treated with cream or lotion prior. It is uncomfortable to sleep with but a necessary hurdle to heal your heels!
