You Pick the Connection Type
Simply remove the aerator from your kitchen or bathroom sink and use one of the included adapters to convert to a standard garden hose thread. Then use the included hose to 1/4" tubing adapter. Or connect directly to your washing machine spickot.
Float Valve Included
The included Float Valve makes it easy to fill tanks, containers and aquariums automatically. The float can be adjusted as needed. Simply drill a 7/8" hole and install with the included hardware
Auto Shut-Off Solenoid & Check Valve
The included ASO and check valve will shut-off the wastewater line when the filtered water line is stopped. This means the RO/DI unit can be plumbed to a water tap or use the included float valve.
1/4" Tubing & Easy Connectors
Use the included 1/4" tubing to easily plumb your Twist-In RO/DI unit. The tubing simply pushes into the press-fit connectors 5/8" and locks into place for a leak-free setup.
Translucent Cartridges
The sediment and DI resin cartridges feature translucent housings to view inside the cartridges. You can see when the sediment cartridge is discolored from filtering out the particulate and when the DI resin changes to tan color and should be replaced.
Specialty Plumbing Components
Special 90° Elbows make it easy to customize the installation of this RO/DI unit. This allows the unit to be used with an optional booster pump and/or pressure tank for drinking water applications.
Live in the NYC Area?
Based on information presented in the most recent Water Quality Report, you must use an additional pre-filter prior to the Twist-In RO/DI unit if you are on the NYC area water supply.
Are you on well water?
People on well water often have CO2 in the water that can quickly deplete the DI resin cartridge. If you are on well water, check for CO2 prior to purchasing the Twist-In RO/DI unit.
Chloramines in your water?
The Twist-In carbon cartridge removes chlorine from tap water. However, it does not remove chloramines. Check with your water company or test your water for chloramines prior to purchasing.

Good system it filters my 450 tdm tap water down to 1 or 2 tdm, my tap water is 50 tdm away from needing 2 sediment filters. It works fine for my 50 gallon aquarium needs.

Fantastic. We run a fish breeding room for both shrimp / snails and fish and this RODI has been amazing. I've never spent less than $250 on one before over the last 17 years in this profession, but this is by far the best unit I've ever ran. 75 gallons a day, and the TDS meter is coming in appropriately. I wish I had been using these sooner! No leaks, float value works beautifully.

I had the RO buddy & it became such a hassle. So many issues! This one however was super easy to set up, moves relatively quick & produces clear water that I can re mineralize. I’m very happy with it. It’s also easy to change the cartridges. It’s perfect for my aquariums. It’s definitely worth the price! I will update after I’ve used it for awhile.

This unit was purchased specifically for making clean water for Caridina shrimp. The value and quality were hard to beat in my opinion. The ease of filter cartridge changes is awesome! I was having an issue with me float valve and I reached out to their customer service team. They responded quickly and it was a simple fix that I completely overlooked in the instructions. Needless to say, I know that if I have questions or concerns, they are there and ready to help their customers. That goes a long way nowadays with internet shopping!Regarding water quality specifically, I have hard tap water from the city. It's loaded with TDS averaging above 300 and conductivity at 650+. After the initial flush of the filters, I was getting a solid ZERO on both parameters! I couldn't ask for anything better! The auto-shutoff solenoid is an awesome part that is included in with this unit. I'm able to fill my plastic tote with water and rest assured that the unit is not constantly running and wasting water. I would 100% recommend this unit to anyone, not just an aquarist, for their RO needs. Excellent product and value!

Great RO system, especially for the price. This kit comes with a little more stuff that most people might not need. I bought this mainly for fish and shrimp keeping but also for drinking water. The adapters did not fit my pull down kitchen sprayer/hose nor my bathroom sink, but it will fit a garden hose or a larger sink thread (I think my pull down hose is 3/8" and is much too small for the step down adapter from the garden hose size). I had a homemade stand that I installed it on.The main issue I have that makes it 4 stars and not 5: these connectors love to leak. I had to adjust them several times outside (while it was raining lol) to see if they would stop leaking. They would, but if they get moved slightly they can start leaking again, so when you set this up make sure you can see it won't leak when you turn it on (I had to keep going outside to the garden hose - I'll install a spigot on the side of the stand that I can connect to periodically I guess so I don't have to run around and turn it off). Once you get the tubes securely fastened and positioned how you need them to be so you don't move them much or at all when using the system, there are no leaks.Initial testing shows 1 or 2 ppm TDS if not 0 - those TDS meters are not perfect but it was moving around 0-3 ppm. Water tastes great. My city water pH is currently high at 8.4-8.8 (which is why I bought this). Tested pH was around 6.4-6.6!! 75 gallons per hour is a little over 3 gallons of RO water per hour. I'm using 5 gallon buckets for now until I get longer tubing or figure out a better solution - but if you're like me it takes about 20 minutes for the waste water to fill a 5 gallon bucket if you have a garden spigot on about a quarter turn. This equates to 15 gallons of waste water for every 3 gallons of RO water, so about a 5:1 ratio which is what I expected. My TDS overall is not that high (160 when testing the waste water), so I could use it for plants, just nothing that doesn't like high pH.tldr; works as advertised, install not that difficult but the tubing is sensitive and may leak and need adjustments but will work fine after making said adjustments. just have someone with you if you're not installing it in a location where you can turn the water on and off and see the unit at the same time!

Product arrived broken. The waster water valve part had snapped clean off. Tried gluing it back on to no luck.
