Easy to Install

This works great and was very easy to install. We did not encounter any problems during assembly. The water tastes like RO water and the PH and TDS come out perfect. We have not had any issues with this system and find it easy to recommend!

Just Installed

Very easy to install with clear instructions and color coded water tubing. Make sure you push tubing into quick connect fittings with a good amount of force. Footprint of system is relatively small which was great for me because I didn't have much room to work with. The quality of the faucet is great.

Easy to replace filters

I like that I will be able to replace these filters myself. I also like the feature that it will turn itself off if there is a leak. My last system was leaking slowly for months before I noticed and destroyed my cabinets!

Great Customer Support

This system was easy to install. And the water tastes great. But what really impressed me was the customer support. I chatted with them online twice. They were quick to respond, helpful, and nice. When I made a mistake during the install - which is not easy to do, by the way, the step by step videos are awesome - I called and they answered quickly and respectfully. The easy twist off filters was what sold me on this system.

Installed myself in under an hour, crystal clear water.

We live in Las Vegas where the GPG is 14+. I installed it to our main faucet line without softening, so the membrane probably won't last as long but that's ok. Flow is quick and the reserve tank holds more than enough water for a household of 3 people. Installation was easy, the instructions were in proper english.The water is crystal clear, it leaves no deposits on our drinking glasses. The water tastes a bit sweet, I'll take the other reviewers' suggestion of using the Alkaline filter next time, but it's not a big deal.

QUESTIONS & ANSWERS

Ask a Question
  • Will this system remove salt from the water?

    The RO System will remove salt from the water. We are assuming you are either on a water source that has amounts of sodium or you could be referring to the trace amounts of salt that can be found in softened water. In any case an RO System will effectively remove any traces of salt and various other contaminants from the water. 

  • can this be hooked up straight to a refrigerator water line instead of the included faucet?

    Yes, you can actually install it closer to the fridge as long as there's a source of water, along with a drain. The output of the RO will go to the refrigerator directly instead of going to its own dedicated faucet.

  • Need to know what size hole to drill in countertop?

    7/16” (11 mm) drill bit or approximately the size of a dime is needed. 

    Here is the RO Owner's Manual which goes over that part of the installation in detail. 

    PREMIER SERIES DRINKING WATER SYSTEM OWNER’S MANUAL

  • How long do the filters last?

    • RO Pre-Stage Filters  

    The pre-sediment and the pre carbon (AF-PR2) & (AF PR1): Replace every 9 to 12 months (Private well water source may need to replace pre-filters sooner than 12 months due to heavy sediments and other particulates).

     

    • RO Post Stage Filters

    RO-Membrane and Post ALKALINE FILTER (AF-MEM75) & (AF-PR4ALK): Replace every 18 months – 24 months (or two years) (Private well water source may need to replace membrane sooner than 2 year due to lower source water quality).

  • Based off the manual, this system is recommended only for 10 grains per gallon or less. This should be advertised on the item description on this site. If I wanted to use this system with gpg >10, do you offer filters that can accommodate the hardness demand?

    We recommend 10gpg or less for our RO systems to help prevent scaling and build-up inside the system. Our water softeners would be the only system that can remove hardness. Please feel free to reach out to us and we can get you set up with a system that meets your needs.
