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

Great stuff!
Color: #3 Rose Gold
Trying to give 4.5 stars. It’s phenomenal! My only .5 is that is absolutely does rub off on clothing. I’m going to a party tomorrow and I’ll try using setting spray after application. I love it though. Light weight, no odor and shimmer you can use on body, hair and even accessories!

Beautiful, Subtle, Long Lasting Sparkle
Color: #3 Rose Gold
Sprays easily and seems long lasting, (stayed on for more than 3 hours of light household work). The glitter is very fine, and that’s exactly what I wanted, it is not visible dots or shapes- my arms just sparkled when I moved them and with the changing light. Feels like nothing is there. Nice! Doesn’t feel especially moisturizing, but hasn’t dried my skin out either.

Great to have this on hand
Color: #3 Rose Gold
I bought the rose gold to add some shimmer to my body and hair. It's the right amount of shimmer to stand out. Looks super cute, it sticks easily and when you wash it off, the glitter comes off easily. The smell isn't the best, but it isn't terrible. I just use my own fragrance after I put this on. I love the glow it gives my skin and the shimmer it gives my hair. I'm going to buy this product again. Second time buying this and I love it!

4 out of 5
Color: #3 Rose Gold
I loved the glitter. It doesn't leave me feeling gross and sticky. The color is very pretty. The little pieces of glitter are really fine which goes well on clothes and the whole nine. The only thing is, the spray bottle is sad. I had to switch it into a different bottle to actually apply. Overall, I really liked it. I feel like I got what I paid for.
