15 Gallon RO Water Storage Tank for Commercial RO Systems

Flexwave Composite Pressurized RO Tank


Flexwave RO 15 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 FWRO15 can be used as a direct replacement for ROMATE15, which we have discontinued.

lower quality casting but very functional. reseason is a must. good purchase otherwise
Size: 2-Quart
this was an amazon primeday impulse buy. initially when reading the reviews i was skeptical of its quality at all and attempted to cancel but i could not(too late). i figured it wasnt the end of the world when it showed up as i only payed 20$ on sale for it. well, it turns out thats a steal of a deal for this pot. when i opened the package i checked it all over with a magnet. who knows it could be lower quality pot metal but its definitely ferrous material. the season on it is real, like what you find on a lodge pan but not done well, it was sticky. so i boiled a pot of water and scrubbed the lid and pot insides with a scour pad to remove most of it. it looks exactly like youd expect cast iron to look and it has a smell reminescent of a deseasoned wet cast pan. so i trust it. my version should be 2qt, i do not know if they make larger versions. i trust it to work in the future and it seems like itll make great stews and soups. possibly even a good camp pot if youre into carrying cast iron with you. its not massive and its not overly heavy at maybe 3 lbs. it was a good buy and im happy with it. plan to add a bail so i can use it for camping as well as kitchen use. in conclusion its a lower quality casting but still very functional. it must be reseasoned to be useful but for the price i almost expect it. most cast iron cookware are not made to the spec they used to be and thus require love from the owner to really work well.

Amazing Dutch!
I've been on a cast iron craze recently. I think back to college when I'd watch Yan Can Cook, and Chef Martin Yan would lean over into the pan and say, "It's got to be hot hot!" I finally realize what he means after all these years of cooking. Heat makes for awesome cooking. It gives wok hei. It makes the difference between a juicy, seared steak vs a dry, tough one. When I discovered this secret, I was like a kid in a candy store, picking this cast iron, that cast iron, another cast iron, please. When I bought the 5 quart Amazon Basics dutch oven, I figured that at the low price, if it came with issues, it wouldn't be an expensive loss. I was impressed with the packaging. Amazon did not want this pot to break, so it had form fitted Styrofoam everywhere, pot and cover nicely separated. There was a nice Amazon Basics logo on the bottom of the pot. Upon close inspection, I thought I found a hairline crack on the cover. It seems when they casted it, part of the iron folded over on itself and formed the line. Someone then took a sander and sanded part of it slightly. What I thought was the hairline crack was actually the edge of the polished surface. The next day, I cooked bacon in it. I fired up the Camp Chef Explorer stove and cooked two pieces of bacon in the pot. I also flipped the cover upside down and cooked two pieces of bacon in it. The cover makes a very nice ad-hoc skillet. After it cooled, I inspected the cover again, and it is not a hairline crack. The bacon seasoning started covering up both the polished and unpolished surface into a nice, uniform seasoning. The following day, I made chicken stew in it. While carmelizing the onions and carrots, I made another nice discovery. The flat bottom lends itself nicely to efficient stir frying. Sometimes, in a wok, I come across the problem of the bamboo spatula not being able to get under the food, so I end up chasing the food up the sides of the wok unable to flip it. The part of this dutch oven where the bottom meets the sides creates a nice angle that pushes the food onto my bamboo spatula for easy flipping. Yesterday, I took it to my parents' house and made artisan bread in it. Everyone was impressed with the crispiness of the bread crust. Everyone came back for seconds. Needless to say, I no longer have the dutch oven. My mom liked it so much I gave it to her. It's almost Mother's Day, and who would say no to their mom? *ahem* Amazon...another cast iron, please! LOL PS: The lid fits a 10 inch skillet but not a 10.25 inch skillet. It falls into a 10.25 skillet.

Perfect for Bread
Size: 2-Quart
I bought this to make the bread in the book "Bittman Bread" by Mark Bittman and Kerri Conan, which I also bought here on Amazon. This Dutch Oven has been working perfectly for the last 6 months of baking. As a bonus, it's much less expensive that the same size Lodge pot. I've got a 5-1/2 quart regular and a 7-1/2 quart enameled both from Lodge and use them all the time for stuff, but I only use this 2 qt for the bread, usually more than once a week. It's great. Look up that "Bittman Bread" book and buy it from Amazon (I don't think you can insert links in the review), then definitely buy this Dutch Oven. I highly recommend both.

Excellent Enameled Cast Iron Dutch Oven
Color: Red, Size: 5Qt
This Dutch oven has quickly become my favorite piece of cookware in the kitchen. The enamel coating makes cleanup surprisingly easy, even after slow-cooked meals. It heats evenly and keeps food warm for a long time after cooking. I’ve used it for soups, roasts, pasta dishes, and homemade bread with amazing results every time. The red color is beautiful and looks great sitting on the stovetop. It feels heavy and durable without being impossible to handle. I would absolutely recommend this to anyone looking for a high-quality and versatile cooking pot.
