CRSpotless - resin replacement time?

I thought I remember this topic being covered recently, but I can't seem to find the thread. I've had the DIC-20 for a couple of months now and I use it roughly once a week for a rinse-down / foam gun soak. I do a normal wash once a month. The TDS meter has been reading 000 so far.



Today, my contractor was using the hose and when I borrowed it back from him, I plugged it into the braided hose end and turned on the water flow from the quick disconnect. The flow from the outlet itself was already full blast.



I assume I screwed up the resin? I didn't realize this until a few hours later when I noticed water spots on the paint while inside the garage. I tried washing again, only to realize the meter was now reading 047 (plus or minus a few). I'm assuming I induced an air gap and screwed up the system so I need to do a complete resin change now? If so, what an expensive lesson to learn. At least I have that extra resin pack that came as part of the Costco package.
 
Hmmm....it does sound like that full-flow might've disrupted the resin.



You might give CRSpotless a call, they're *very* friendly and helpful and might say something worth hearing.
 
The full flow probably killed it - believe it or not, I killed my brand new resin after 2 washes (DIC-10) by using 4GPM instead of their max. 2.5GPM. A whole 1.5GPM is enough to kill it, so you probably murdered it pretty good

The DIC-20 will allow a Max of 4GPM. Though if he blew past that he likely killed his resin like you did with your DIC-10.

Just to wrap up this thread, the company's customer support told me to try running water through the system for a couple of minutes to see if it'd clear up the issue and bring the TDS readings down (because by that time it was varying between 047 and 105+). Unfortunately, it didn't work, so I just swapped the resin out with some new one.



I'm pretty happy the Costco bundle came with extra resin. I just have to be more careful about the initialize burst of water going through the system when I start up each time from now on...



BTW, I noticed that the old resin smelled kind of "rotten" and some of it was a darker brown. Is this normal if the resin is "used up?"

When I changed out my resin, I noticed that the resin was also dark brown in color. I thought it was because it was full of water. I didn't notice the "rotten" smell in mine. Perhaps if yours sat for a while and was not used, it formed some sort of algae or something.



I started draining mine after each use so the resin wouldn't "go bad" and I noticed that when I pulled each cartridge out and shook them vertically to get the water to drain out of the bottom as the water drained out, the resin went back to the gold color. Once the entire cartridge was gold, I knew all the visible water was out and I put the cartridge back into the blue housing. I know this doesn't answer your question directly, but I hope my experience helps.
 
I'd like to pose a question to anyone who has owned a CRSpotless unit for a year or more. Given your model (DIC-10, DIC-20, etc.), your frequency of washing, size of car, etc., how many rinses did you get out of a single set of resin? Do you use the filtration system just for rinsing, or for washing as well, etc.?

I've had the DIC-20 model for over a year and I can't come up with an accurate guess. I used to use it for my foam gun pre-soak and wash and final rinse using a 1.8 gpm Karcher electric pressure washer. I went through the resin much faster than I thought I would so I've scaled back to using it for the final rinse only. Our water here in Dallas is pretty hard so I know that accounts for some.
 
What does "disrupted the resin" mean?



I've had mine since last Christmas, and I'm on my second batch of resin, and I think I'll need more pretty soon. I have the DIC-20, and use it for one or two cars a week. I started out using it for everything, and now I just use it to rinse. I keep the presure turned down, but not sure what gpm I use. Do you guys have a guage for this, or figure it out manually?
 
You guys are confusing me...I don't know if you can "disrupt" the resin. As I understand it, the slow fill procedure is to get all the air out of the housing, as you can wind up with a big air bubble the top and the water will bypass some of the resin.



CR discourages the higher flow rates because if you flow through too fast, the ions don't have time to exchange/be removed, which is standard DI practice (to flow limit), although I guess it could also be to keep from channeling the resin, but I presume there are grids, etc, because otherwise you would be barfing the resin out of the thing, IIRC the CR cartridges actually have what looks like a filter disc.



I'm thinking I was getting about 50 rinses from my DIC-20 before I decided it was too much of a hassle, and got tired of wheeling the thing out and putting it away, and decided it was easier to run the soft water hose from inside. I kind of envy you guys with the new blue ones, they look a bit neater and from what you are saying actually have TDS meter rather than the 20K ohm light (or whatever it is, 15K, 10K?)
