Review: Great customer service and product - No fault of the seller, the package was delivered to the wrong house, and it wasn't a neighbor. Contacted FedEx to try to find it. They closed the case before completing it, and I had to call and complain. They reopened it to say a couple days later, we can't find it. Membrane Solutions quickly responded to me after I reached out & provided case and tracking. They quickly had another package in route. Good customer Service, and the product works Well. I've been using them for a few years for a Whole Home RO system.
Review: Nicely made RO membrane housing - Important note: the pink connector is also a check valve and it matters where it goes in the system. Otherwise, this is a nicely made RO membrane and housing that I used to convert a 3 stage filter into a classic RO filter after the manufacturer (Express Water) told me it couldn't be done.

- [About RO GPD Ratings] GPD ratings are based on tests performed under specific water conditions (Urban tap water, 25°C / 77 °F, 100 PSI). Every time the temperature drops by 1°C / 33.8°F, the GPD Rating drops by about 3-4%; every time the pressure drops by 1 PSI, the GPD Rating drops by about 1 - 1.5%. For example, a standard 150 GPD RO membrane, at a temperature of 10°C / 50°F (or a pressure of 50 PSI), the GPD Rating is about 75.

### ⭐⭐⭐⭐⭐ Upgrading my review from 1 star to 5 star based on new information.
*by D***1 on October 22, 2020*

I originally gave this "DIY" RO filter and pressure vessel kit a one star rating because 99% of the water went out the waste (brine) outlet and there were only drops coming from my RO faucet. Well I didn't have everything I needed to get a usable amount of RO filtered water which would be being able to fill an eight ounce glass of water in less than a minute (vs a frikin day). With this 400GPD RO kit I was expecting to fill that glass in maybe 15 - 30 seconds based on what I have seen with a few of the full RO systems costing around $300-$400 that some of my neighbors had. After dealing with the seller's representative I would also give the seller (and his rep) a five star rating. The end result is that I am now getting the output I expected. As was my original review this new updated one is a bit 'wordy' . . . The reason I didn't get the expected output was more because of my lack of knowledge of RO systems. First of all in my defense for the scathing review and one star rating I gave I must point out that this is being marketed as a DIY kit. In my opinion it is not a DIY system - at least not a complete DIY. However it is a very good deal for a 400GPD filter kit that a Do It Yourselfer would need and want to build a complete RO system. To me a DIY product (stating "Make your own reverse osmosis water filter right now!") implies all I need to do is add these components to an existing filtered water line and feed the permeate RO filtered output to a dedicated faucet on my sink. While I didn't expect this kit to come with a RO faucet and some of the other parts I would need; I did (and still do) think this DIY kit marketed as it is should come with everything needed to put water into the RO pressure vessel and get a usable amount of RO filtered permeate water. However you need one more very critical component to get a usable amount of RO filtered water. That component is a Flow Restrictor (FR). With the Flow Restrictor you will be lucky to get even drips of RO filtered water. Without the Flow Restrictor there will be no back pressure to force water through the internal RO membrane and most if not all of the water will take the path of least resistance (practically no resistance) and go out the waste (brine) outlet of the pressure vessel. Basically this is why the container where the RO filter is placed is called a "Pressure Vessel" in the first place. Flow Restrictors (FR) are rated in what amount of restriction they place on the flow. It's not a 'one size fits all' deal. You need different sized FRs for different sized RO filters (50GPD, 75GPD, 100GPD and 400GPD etc.). Simply stated the amount of restriction needed is based on what you are putting in and and what you can except as an output. So there is a ratio if input to output. There are many more variables and it is more complicated than that but this is what it all boils down to. For most RO systems for every 3-4 gallons or raw unfiltered water you put in you get 1 gallon of RO filtered water out the permeate output. The other 2-3 gallons goes out the brine (waste) output and 'down the drain' so to speak. In the US where water is cheap and plentiful in most places some people might use the waste water output for watering the lawn, garden or taking baths or whatever other purposes. It's usually not 'bad' water coming out the waste output as the term waste implies. Also, If you don't want to have to open and close the input water line every time every time you open the faucet get some RO filtered water another component you will want is an (optional) Automatic Shut Off Valve (ASOV of ASO). If you are feeding the water into a holding tank or reservoir of some sort you would need at the least a float valve so that once the tank is full the input to the to the RO filter shuts off. This would actually be another type of ASOV. I only want RO water to drink where from what I understand a lot of people use RO water for aquariums, making maple syrup, hydroponic gardening etc. and use a more manual based system and may not use an ASOV - but I think that nearly all RO systems do and should. I did a LOT of online research before I bought any of the components to build my RO system and nowhere that I look was it pointed out that the FR is a critical component nor was a FR even mentioned. I already had a somewhat sophisticated filtration array in addition to a basic water softener for my rust colored well water with a very high amount of Totally Dissolved Solids (TDS). Bare in mind that a water softener does not remove any TDS it only exchanges the dissolved calcium and magnesium etc. solids of with sodium based dissolved solids so you still end up with about the same amount of TDS at the output as you had at the input. For washing clothes and showering the sodium based TDS was not a major concern for me but I didn't want any TDS or other crap (almost literally) in my drinking water. I should add that you DO want some calcium, magnesium and other TDS in your drinking water because your body does need some minerals. Unfortunately RO filters or 'throws out the good with the bad'. They actually make another 'filter' that adds back 'good' minerals into the RO filtered water after the RO filter. However you don't want a lot of other TDS in drinking water and some are very bad for your health. At the time I bought this 400GPD kit it did not come with a Flow Restrictor and the seller did not even sell them . . . or mention that one would be needed. In my correspondences with the seller I pointed this out. The seller contacted me after reading my review to find out what the problem was and replaced the kit at no additional charge. I have left a lot of bad and good reviews for many of my Amazon purchases I was impressed that the seller did so being for me this is not a common practice. I would rate the seller with 5 stars also.
