   Super easy to install and works great with my water filtration system. My system doesn’t require a tank but why out a tank it takes around 10-20 seconds to get the pressure up so the manufacturer recommends a tank to have no pressure delay. Now I have instant pressure.

   This made a great addition to my basic RO system. Nice compact size and makes the RO water flow much better.

   The company came to service my systems, and quoted me $250 for a new tank. this one is a tad smaller, but not noticeable for us! Works great!

   Our RO system lost most of its storage capacity, figured out that the tank diaphragm failed.
   This replacement tank works great and is a little smaller than our original 4 gallon tank.
   Since it’s smaller, I was able to store it on its side instead of upright, in hopes this puts less stress on the new diaphragm.

   Purchased this as a replacement for the one that went bad on my reverse osmosis. For the money I highly recommend this. Quality and an affordable price.

   It was easy to set up, it feels strong yet lightweight. I used a bicycle pump and took it to 10psi. No issues whatsoever.

   This tank has failed within 12 months and I didn’t know until I got my water bill and had the water company come diagnose. The tank pressure leaks internally and my RO runs constantly which used 2,500 gallons per month. I DO NOT recommend using this company for your RO tank replacement!
   UPDATE: I contacted the company and they were gracious enough to send a replacement tank. I am revising my 1 star to 4 stars… I will follow up if the new tank lasts or not.

   I have a WaterDrop tankless RO system. It suffers from 2 problems 1. Takes a couple seconds to start 2. TDS creep: TDS slightly increases at the beginning of every run from unfiltered water getting through RO membrane (it happens a bit in traditional tank systems too) This fixes both problems 1. There’s always water there when I turn on the dispenser 2. The pump only has to turn on every ~6 glasses of water which means it can run a lot longer but less frequently thus eliminating most of my TDS creep Tankless RO with a tank?!? Yes. This way I get the best of both worlds (but more expensive initially). I don’t need to worry about using all my supply of water and running out. I have a higher efficiency than with a traditional tank system. And I still have reserve water in case the city shuts off the water. Super easy to maintain, less components, and I love it!

   Product weight is listed 9lbs and I bought it under that premise thinking it would be heavy duty. Felt really light when I picked it up and decided to check the weight. It’s 5 lbs. See picture. Tanks with similar weights can be bought for lot cheaper and they come with free ball valve. Returning.

    After more than 10 years of use, the diaphragm in my Watts tank failed. Instead of purchasing a whole new reverse osmosis system, I replaced the tank with one of these. I also took the opportunity to install an isolation valve for easier future servicing, so I won’t have to drain the system when changing filters. I’m very pleased with the results, and it has proven to be a cost-effective solution.

    1 month in after I had to replace the old tank after the bladder failed. Working great so far
