Product Description
These four stage units include the most important components of RO/DI systems, and also include the most popular set of accessories for optimum performance and operation. Units come assembled, and include: clear housings, 1-micron poly sediment filter; 0.5-micron, 20,000 gallon carbon block; RO membrane, rust-proof bracket, pressure gauge, housing wrench, drain saddle, and 6 feet of blue, yellow, and white tubing for the supply water, drain, and purified water. These units also include a filled, refillable DI resin cartridge. Semiconductor grade resin assures you the best water quality possible and the refillable cartridge provides an economical option for replacing the resin.
We offer an expansive range of options and add-ons, some of which are described below and can be selected above. Not sure what options would be best in your situation? Need an extra stage? All our water treatment systems are built in our shop and can be customized. Please give us a call - we have a specialist waiting to talk with you!

RODI Capacity Depending in large part upon which RO membrane is used, RODI systems are configured to produce a specific number of gallons per day. There are several things to consider when selecting the capacity best for your situation. If we consider a 75 gallon per day system for example, a bit of arithmetic shows the system will produce 3 gallons per hour. So although you may never need to produce 75 gallons of RODI water in a day, most users will find a "gallons per hour capacity" more practical.
24 GPD = 1 GPH; 36 GPD = 1.5 GPH; 50 GPD = 2.1 GPH; 75 GPD = 3.1 GPH; 100 GPD = 4.2 GPH; 150 GPD = 6.3 GPH
These capacities will be met (+ 20%), if the feedwater meets factory specifications (see the table below). Also consider how well the various RO membranes clean the feedwater (a higher "rejection rate" results in cleaner RO water):
ASOV Kit Auto Shut Off Valves stop the flow of concentrate (a.k.a "waste water") when the flow of purified water is stopped by a separate valve (for example, a float valve). This Kit includes a check valve and ASOV (both plumbed in for you), and a float valve with built in bulkhead set to accept 1/4" tubing.
Flush Valve Routine use of a flush valve can help extend the useful life of the RO membrane. Options include a manual valve the user should open occasionally; or an automatic valve powered by a transformer (included) that opens once per hour for 18 seconds - giving you one less thing to remember to do!
DI Bypass Many users wish to access their RO water before it reaches the DI stage. With the simple opening of our unique 3-way valve, RO water exits the system without passing through the DI resin. Say goodbye to shortened DI resin life due to TDS creep! Provides a convenient source of RO drinking water, and facilitates sampling the TDS of RO water with a handheld TDS meter. Includes 6 feet of 1/4" tubing.
TDS Meter These meters are an important tool in assessing the purity of your treated water. Both inline and handheld meters are available. See our Meters and Controllers for detailed descriptions of each. If you select an inline meter for your new RODI system, we recommend the TRM1 - the only 3-probe TDS meter on the market. Allows the monitoring of TDS of 1) feedwater (tap water), 2) RO water, and 3) DI water.
Feedwater Supply Fitting Feedwater Fittings are used to tap into your plumbing to supply water to the system. Depending upon where in your home or facility you install the system, we have a fitting that will work for you!

no complaints!!
Posted by john anderson on 21st Apr 2015
While I don't have much experience with RO/DI systems I do like this one. It was easy to set up and easy to use. Even better was the customer service - patient and friendly in answering my questions without pressure to buy everything under the sun. I feel I got a good product with a few upgrades for less than the competitors. Couldn't be happier with my purchase

RO/DI
Posted by Jonathan on 3rd Apr 2015
I purchased this RO/DI system, and it was my first system. Very easy setup. Instructions were fairly easy to follow. Works as it should.
I had a few options added. I opted for the ASOV, DI By-Pass and the TRM-1. Glad I chose the options.
The ASOV prevents my waste water reservoir from overflowing until I can get a permanent drain setup.
The DI By-Pass is excellent for having water with a few PPM for other things like drinking or watering outdoor potted plants.
The TRM-1 is fantastic, I love being able to see what the PPM is at 3 locations without having to have bypass valves for them all and testing each individually with a TDS pen. Thanks Buckeye for a great product!

Mr. Saltwater Tank guy on youtube recommended this product and brand name.
Posted by Sonny on 15th Mar 2015
As a newb to RODI had some issues early on during setup and Buckeye was quick to respond via email.
Customer support is A+

Can't say enough good things. My TDS meter shows 0. What more could you ask for? One of the fittings had a slight leak. Nothing a little plumber's tape couldnt fix tho. Overall very happy!
