Intro, first post, RO/DI question

4 parts waste water to 1 part purified water is your goal.

My bad, somehow I got to thinking waste water was the 1 in the 1:4 ratio.

You can call AW&I to optimize your unit

The orings are specific to the brand of housings that your vendor used to buid the system. If you contact them they should be able to sell you replacements.

And yes, you MUST have orings on these housings - that is where they seal - not at the threads.

You can control/change the ratio of waste water to purified water on any RO system by changing a little $4 part called a flow restrictor.

Normal RODI runs 1 part good to 4 parts waste (1:4) with average input water. If the water coming in is very dirty, then you might not even get 1:4.

Some of the newer units run 1:2 with average water. Some of the best unit on the market (read very high priced) claim 1:1.

I bought a SpectraPure unit rated at 1:2. The water in my house seems to be pretty good because my simple test showed I was getting closer to 1:1.7 after original flushing the day I hooked it up. TDS meter in showed about 29ppm and out at 0ppm.

Your milage may vary based on a whole lot on things.

I contacted the vendor, and they would only sell me a new canister. I just put a bucket under it for now....

No way. Air Water Ice told you that?
