20 Gallon RO Water Storage Tank for Commercial RO Systems

Flexwave Composite Pressurized RO Tank


Flexwave RO 20 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 FWRO20 can be used as a direct replacement for ROMATE20, 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.

Premium Quality at an Affordable Price
Size: Large, Color: Dark Navy, Size: Large, Color: Dark Navy
I recently purchased this men’s suit and was genuinely impressed with the quality and fit. The fabric feels premium, comfortable, and well-stitched, giving it a classy and elegant look. The fitting was true to size. The color and design matched the pictures exactly. Highly recommended for anyone looking for a stylish and affordable suit.

Great quality for the price.
Size: Large, Color: Black
All I have to say about this suit is WOW! I lost a good chunk of weight and needed a new suit for an event. Given the price I gave this a shot, and I am really impressed with the quality for the cost. The size is perfect, and the pants are comfortable with an internal elastic that looks and feels nice. The design makes it so the pants don’t slip down with nylon and silk shirts. Looks just as good (if not better) than suits in the $300 price range. I can’t speak for the other colors, but the black suit is exactly what I needed. Let’s see how long the suit lasts!

Amazing suit for the price
Size: Large, Color: Black
So I didn't really need a suit for anything. But I've been wanting one just in case. As such, I wasn't willing to spend a lot. Yet I still wanted to look good when I wore it. This suit is amazing. I honestly would fit between a medium and a large, and with my current trend down in weight, I may buy an additional in medium(I mean, for under $100, why not?). While my shoulders have always been a little wide for what fits my waist, the large seems to accommodate even more than I need. I worry if the medium will be too tight, but that's for another day. The pants are a little long, to be expected considering I generally wear 30' pants. Easy to hem. The vest seemed a little loose, until I found the adjustment in the back. Now it is perfect. I may still need to go to a tailor for a more custom fit, but for the price it can't be beat. And I of course haven't tied a tie since I was 16, so time to relearn that. As far as quality goes, the fabric and stitching all appear to be excellent. I went with the black, as I don't particularly look great in gray, and navy out here seems more suited for church than anything else. The quality of black is excellent. The quality of the pants is good, but I will still be favoring my dress pants that already fit well. I especially love the angle of the beast cut(whatever it is called). Whether I choose the vest or not, the black contrast with all of my dress shirts is fantastic. I will include photos sometime when I'm not too self-conscious about taking selfies.

Really amazing suit that looks like a million bucks!
Size: Large, Color: Black
This is the second suit we bought by Lupurty. The first was dark navy and fit so well and looked so good that we got one in black for our son’s wedding!
