CR Spotless Resin - Time to Change?

The meter on my CR Spotless is reading near 30 ppm. According to the CR instructions you should change resin at this time.

I decided to replace them today. But, when looking at the cartridges, with half dark resin and half light resin, I started wondering if there was life left?

What do you think? Photo below.

 

It's a "mixed" resin bed of two different types of resin beads. (I don't have the specifics of both materials offhand) That's the way it should look. You have clear cartridges nice, mine are white.

 

I only received one type of replacement resin with my CR Spotless, Mixed Ion Exchange. Are you saying that I should have a bag of another type of resin to mix with the two bags I received?

 

I think your wife will kill you for bringing "that filthy thing" into "my living room".

 

No you have the right replacement, it's a mix of anion and cation resins. The cation resin changes color (becomes dark) when exhausted, while the anion resin does not.

 

The CR Spotless System
DI100WM provides approximately 100 gallons of mineral-free, de-ionized water that will provide spot-free vehicle washing and remove hard water minerals, based on your water input quality. The resin used is a mixed-bed resin, which means the anion and cation resin is mixed.

Consisting of two 10-inch de-ionization housings that feature replaceable cartridges that simply slide into the watertight tubes, this unit can be mounted next to your hose bib and comes with pre-drilled mounting holes. Using a cat ion/anion mixture; you get twice the filter life than the mixed bed which comes with the unit.

The cationic resin goes in one chamber and the anion resin goes in the other. You won't get the 0 PPM reading that you would get with the mixed bed, but it'll be around 5 PPM (spotless if less than, 25-30PPM)

Input TDS Level Expected Yield
50 PPM 1600 gallons
100 PPM 800 gallons
200 PPM 400 gallons

 

If they were seperated into two chambers that would be great because you could do a quick regeneration yourself with some caustic and some acid. I deal with de-ionized water everyday in my profession and have written about it a lot on here if someone wants a more detailed explanation of how it really works.

BJs I've never seen my spent resins look like that and I've changed them out probably 4 times. Unless you are in dire need of doing some washes before you could get a re-fill I'd just wait until I got a refill and start over. I wish they were seperated as then just a little acid and some sodium hydroxide and you could have them regenerated in no time.

I have dumped out one of the chambers, but have not touched the other, other than to take a picture. My system has two chambers, and I have two identical bags of mixed ion exchange. Are you suggesting I replace the one chamber with the replacement since I have emptied it, and just leave the other alone for now?

 

You can do that as I did it once as a little experiment, but it really doesn't give you that much more life before you will see the TDS meter reading above 20 again. Then you put the other one in the one you didn't replace the first time and you'll get more life again but I didn't think I got as much total life out of doing it that way as opposed to just replacing both of them and starting anew. Tried it once and went back to just replacing them both when I replace.

I know you are like me over your car and you'll be much happier just replacing them and starting out fresh again, because the first water spot you see on that beautiful 5 series you'll swear it came from not just changing out both chambers, LOL. By the way I love that avatar!

 

I really want to get this system... water spots make me angry...

 

sry for off topic well maybe it is same..
the cr spotless in costco is that the small cartridges or the big..?
on picture it looks like the long size one but on writing it sounds like the small one.

Imagine that! :thumb:

What camera do you use?

 

The CR Spotless that comes with 2 canisters, do you get 100 gallons of filtered water per canister or is it the total for the unit (2 canisters)?

 

My understanding was the DIC-10 was 100 gallons and the DIC-20 was 200 gallons. Maybe I'm wrong?

 

I purchased mine from Costco and it has two long cannisters.

 

The ones at costco are the big ones

 

thx.. getting back $200 reward back, CR spotless here i come!

one question do you guys also buy the resin from them also? or do you guys know better cheaper place?

 

That is the cheapest price i have seen anywhere

 

I have found Costco to have the best prices on resin refills.
