Great service and good system for the price
By Chau Nguyen
This is a best quality system. I order 2 system from them in one moth. One of them has problem with the tank, the support team call me 2 hours after I was send the email, and the replace tank came three days after. Excellent tech support, and good price. Extra filters will save for another year. Fast delivery, Very easy installation. The system came with white housing and I request them to change all for clear housing. They change it with no extra charge. I can see all the filters though the clear housings. The water came into the first housing. When I see the filter dirty, I change this filter more frequently to keep other filers last longer. Thanks

By J. Cox
I recently Purchased the 5 Stage Home Drinking Reverse Osmosis System PLUS Extra Full Set- 4 Water Filter from Express Water.
I purchased this unit for our home, it was installed under the kitchen sink. Due to my hobby (obsession) of salt water reef tanks, throughout the years I have purchased and used numerous reverse osmosis deionization units from many various companies. The unit I currently use for my reef tank doesn’t require a storage tank but came with a dual TDS (total dissolved solids) meter and deionization stage to remove the last of the TDS. That unit cost twice as much as the unit from Express Water, HOWEVER it falls short of the quality unit I just installed from Express Water. This 5 stage unit is far more superior to the one I paid twice as much for.
For example, this product takes into consideration the task of replacing the filters, they equipped their units with swivel connection to allow for the membrane canister to be open without having to remove the ¼” tubing (which illuminates the possibility to form leaks after a few times of disconnecting and reconnecting the line)
They also perform a pressure test of the membrane canister to ensure no leaks prior to shipment (no other unit that I purchased in the past did that)
The instruction booklet was very clear and even offered color pictures, diagrams and schematics to aid in easy installation. And to go one step further, each connection that needed to be made to the inlet water, waste water, storage tank, and faucet were labeled on the unit itself. This company clearly understands the complexity of tackling a task like this and has taken every step to eliminate frustration, making it easy for just about any skill level to tackle this job.
After installation I followed the instructions and allowed the tank to fill up and then drain it completely, the water was blackish/grey (which is normal due to the final carbon filter being flushed out) then after filling it again I tested the TDS, 7ppm which tells me the unit is doing its job but I knew it could do better than that, in which I then emptied the tank for a second time and let it fill back up. The TDS meter reading the second time was 2ppm…. MUCH BETTER.
You can’t have the good without the bad: the provided ½” slip joint adapter for the feed water wouldn’t work for the shut off valve I had under the sink, my valve has a 3/8” outlet. Luckily I had the right 3/8” adapter handy in my miscellaneous parts from all the other units I’ve had over the years and installed it instead. I’m not sure how feasible it would be to add that adapter to the list but it will save some frustration. I looked on line and currently this part can be purchased for $13 (JG Speedfit ASVPP1LF 3/8-Inch by 3/8-Inch by 1/4-Inch Angle Stop Adapter Valve). Please be sure to take that into consideration when purchasing this unit.
And Lastly, The wrench that was provided is to aid opening the large canisters during filter replacement. However the membrane housing is slightly smaller and the wrench provided will not aid in opening it. This housing was really hard to open and takes some muscle power to get it open. There is a filter wrench to open housing however it wasn’t provided. I can’t provide a name or part number for that though because there’s many options to choose from. However for me, I was lucky enough to have one handy to get it open.
If those 2 concerns were addressed and rectified I would give this purchase and experience 5 gold stars. All in all, the best unit money can buy. I would recommend this unit to anyone that is in the market for a whole home RO unit.

Suggestions For Improvement
I've just finished installation of your 5 stage home drinking reverse osmosis system and I have a few suggestions for improvement. It looks like the faucet included in the package is different than the one in the instructions. I like the upgrade, but it would be nice if you included a compatible quick connect adapter. The Quick Connect adapter that was included (pictured on the right) has threading that is too large to fit on the faucet. The packing nut attachment doesn't work well with plastic tubing.
Also, it would be nice if you included a 3/8 inch T for the cold water connection instead of the half inch one pictured on the left. Many modern kitchen faucets are all one piece and do not have removable flex hoses.
