RO/DI help!!!!

rort · 08/16/2008, 04:30 AM

I am n the market to purchasing an RO/DI unit but am lost on which one I should buy...

The used Sump that I purchased came with an installed kent auto to off.

My question is what would be an appropriate RO/DI to get to connect to this?

AND

How would I hook it up to my garage's Washing Machine!?!?!?!

Thanks for any help and comments!

I just purchased a real nice RO/DI unit from airwaterice.com. It is the typhoon model designed for reef-keepers. They have different addapters you can get plus 100% gauranteed. $175.00 with shipping.

there are many good vendor's here on RC.

For someone just starting out with RO/DI systems I'd suggest the Premium Series 75 gpd RO/DI System from BFS.

Also I'm not a big fan of hooking up a RO/DI system to a float switch, they turn on & off way too many times, and it won't let you flush the membrane after use.

But anyway, here are some RC vendor's who all sale good units.

It's a bad idea to hook up the RO/DI to a float valve like that. If it sticks in the on position (which is a relatively common failure), you'll have worlds of problems you'd otherwise not enjoy. You're better off using a reservoir of 5-10 gallons to hook up to that float switch.

To hook it up to your water lines for the washer, you'll need to just get some fittings to T off of the cold water line. Hit the hardware store!

Turn off cold tap. Unscrew cold water line, screw on a Y adapter with 2 levers controlling flow (brass ok for this, plastic better), screw cold line onto one branch, set lever to open. Screw on rodi connecting line to branch 2. Set lever to closed. Turn on tap. You're connected.

Buy from reputable dealer: with ro/di very much 'you get what you pay for' if you're not dealing with a shark. Better units: 4 cylinders, good filters which last long time. 200.00 is about the top end of what you should pay. The better the bargain it seems, the more suspicious you should be.

I bought one of those 100GPD units off of e-bay when I first started....

Save your money and get a better unit, it will save you $$$ in the long run.

go with airwaterice I just purchased there unit although it came with a broken piece they replaced it no questions asked. You will not find this with a cheap e-bay item.

Make sure you check if your water has chloramines [mine does], it requires a different filter.

rort · 08/16/2008, 12:04 PM

how would i check for that?

AZDesertRat · 08/16/2008, 03:11 PM

Don't worry about chloramines if and only if you use a good ref quality system such as the MaxCap from Spectrapure or Buckeyes Premium 75 GPD which both use a single Chlorine Guzzler carbon block and good DI systems. If you go cheap with large micron carbon blocks in the 5 or 10 micron range and a small horizontal DI then you may have problems with chloramines.

Like atvdave and crvz said. I would not hook rodi directly to that switch. If you have the room buy a Brute (gray) garbage can. They come in 2 sizes. Home Depot,Lowes and even Sam's club carry them. Fill this up with RODI water then top tank off from it. I use a digital timer to turn pump on twice a day to top off tank. Start short on the time and work up till it is right. My 215 and 92 are teed together and only take a few minutes a day to get the job done.
