With the water softening kits, if we combined that to lower the TDS rate, and also used the CRSpotless system, wouldn't we be able to get more DI water out of the CRSpotless due to the decreased TDS rate?



edit nm just read the other thread and i guess it doesn't matter

No. Softened water will not extend the life of a DI filter system because you are merely replacing Ca/Mg ions with sodium and the TDS essentially remains constant. You might extend the life of the DI filter cartridges by using a carbon pre-filter to reduce the chlorine content, but this could also be pretty restrictive to the overall water flow.
 
But wouldn't we want a restrictive water flow to save water? If we're using a pressure washer that limits to 1gallon per min would it really make a difference?



Unless the carbon pre-filter costs alot...

What about that system that Autogeek sales ?

Any word ?

The AG systems are just smaller versions of water softener systems I mentioned in the link above. They are a resin based water softener that can be regenerated with a brine solution. They only produce soft water which is not equal in quality to spot free water from a DI system.

Carbon filters are relatively inexpensive. The restrictive nature I mentioned all depends on how your filter systems are plumbed. There is no one solution that may work the best for everyone. You want a sufficient residence or dwell time for the input water to interact with the DI filters and that is the reason for using an inline restrictor or a pressure washer.



A carbon pre-filter placed before the DI filters was the point I was trying to address where the total flow necessary for a pressure washer outputting DI water may be too low to sufficiently operate the pressure washer.
 
Apparently I have "hard" water - 120-160mg/L according to the 2004 analysis (most recent available online) - I don't know how this translates to PPM, but it's in the 7-10.5 grain range. I think I'd go through a lot of filters quickly...
 
Wait, so the filters efficiency are rated on 350ppm-mg/L water?

That's off the charts in terms of hardness...

http://www.fcwa.org/water/hardness.htm]The water hardness scale[/url] only goes up to 180,

at which point the water is considered "Very Hard".



So most municipal water is VERY VERY Hard at 200-400ppm (according to cheml17l in post #10)?



(I've emailed CRSpotless with these questions).
 
The precise mixture of minerals dissolved in the water, together with the water's acidity or alkalinity and temperature will determine the overall hardness. A single number (TDS measurement) on a scale does not give a completely accurate description of your overall water quality.



The 200-400 ppm TDS reference for municipal water is from a water quality article I read off the internet. I mentioned it mainly as a point of reference and I wouldn't automatically assume that this range would be accurate for all locations. As with all things, the TDS will vary more or less depending on your exact geographic location and how your local water treatment facility operates.



Although you may have what is considered "hard" water, it doesn't mean that a DI system couldn't reduce your water spotting significantly. However, you are right to be concerned about how long a set of DI filters would last you given your water quality because more filter changes equals more $ spent.



The following example is purely speculation on my part and I do not know for a fact that there is a linear relationship between TDS measurement and total capacity of a DI resin filter system.



Example: Assuming that the DI100 CR Spotless system would process 100 gal. of 350 ppm TDS water, you might expect to get ~ 2.5x more water output if your TDS measurement is 140 ppm or about 250 gal. on one set of filters.

Right, so I'm totally confused :)



I just need to be able to make an informed judgement about what kind of longevity I'll be getting out of the system. I've got full specs available for my municipal water system including:



Alkanility

Hardness

pH Units

Specific Conductance

Temperature

Threshold Odor

Turbidity



As well as a breakdown of particular metals, organics, inorganics, bacteria, disinfection byproducts, pesticides, SOCs, VOCs and radionuclides... I just need to know how this will affect the efficiency of the system.
 
I'm still on my original filters from July of last year. I'm using the larger holed restrictor and still happy with my purchase....I'm much more sane when washing the black minivan and not having it waterspot while I frantically try to dry it! :bigups

Ok, I have a unit from "On The Go". It's a portable unit that uses a mixed bed resin system. My water in my area has a average of 213 TDS. Now I have opted to go with the antion/cation set up to alow me to produce more gallons of DI water for alot less money.



Look guys you can break this down anyway you like, as a "rocket scientist" you would do so, but the botom line here is to produce "spot free" water in the most effective matter possible. For those of you out there that do this day in and day out you already know, DI water is uncomparable. The time you save is worth it in itself.
 
For those interested and ready to purchase, please email me the following info:



1. Name:

2. Email address:



Send it to : diwater_grouprate@yahoo.com



I will then forward the list to Chuck at CRspotless. The deadline is today but if you are still interested just email the above infos by Monday morning, May 15. I am hoping that others will get a chance to see it over the weekend. I will ask Chuck to send you an email confirmation to be sure your name is on the discounted list. Hopefully we can get the 10 people we need. Again, no pressure here, just sharing possibilities of a little more savings. Thanks guys.



Quick note: Please do not forget the underscore between diwater and grouprate. The email address is underlined and makes it difficult to see the underscore.
 
I see two terms thrown around here trying to imply the same thing, but they are different, and that is water hardness and TDS



Water Hardness= Also called Calcium Hardness. The amount of dissolved soluble mineral (mostly calcium and magnesium) in a body of water. When in sufficient quanitity, calcium readily precipitates out of solution and forms salty deposits, i.e., scale.





Total Dissolved Solids (TDS)= The sum of all solid substances dissolved in a body of water, including minerals, chemicals, dirt, chlorides, calcium and organics.



So we have two different terms with two different meanings and ways of measuring.



I believe what we are shooting for is to reduce the Hardness.

The folks at Cr Spotless are good people but I've found that I can save money by purchasing my replacement resin from this company: http://www.kfswater.com/Resins/Resins.asp

The resin is the MB-1 and you get about a third more resin for the same price as purchasing it from CR Spotless. You don't have to buy replacement canisters. Just rinse out the ones that come with the unit and refill with your purchased resin. I've already purchased three times from this company and they're also good people to work with.

I bought my CR system a little more than a year ago. I got two sets of replacement cartridges, and am about to put my last set in, so it was time to look at refills. I went to the place Mark mentioned, and the shipping was quite a lot--$45. So just out of curiosity I went to the CR site, to compare the total cost.



Well, everything is different at CR...they have changed the P/N's of the systems, the housing colors, they now have a battery powered purity meter, which seems to connect to both the inlet and the outlet, instead of the plug-in outlet meter, the carts have changed, it sounds like you don't have to pipe anything up when you get it, and all the pricing is WAY up. The big system is almost 150% of what it was last year, and the resin pricing is up almost as much.



The good news is that CR now has some resin options. You can still buy the replacement cartridges, but you can also buy pre-measured bagged resin to refill the cartridges, the cost of this is about 2/3 of what the replacement is, but you can also buy bulk resin from CR. It's a bit more than the place that Mark linked, but free shipping, and I think we Autopians get some sort of discount, so the price will be maybe a little more than half of the replacement cartridges, and about $30 less than buying from kfswater.



I'm not sure if resin prices have increased since last year, and this is responsible for both the higher resin and system cost at CR, whether they were using some cheapo resin that was the root of some of the quality problems noted in another thread, or simply that CR is capitalizing on the popularity of their system to make larger profits. I suppose a bit of it could be that they now have free shipping on everything, and have really just added the shipping cost into the price.

I know there have been some problems with their resin cartridges in the past. Would you still recommend one of their systems?
 
I didn't have any of the cartridge problems (at least not that I'm aware of :o). For me, it's kind of a pain wheeling the thing in and out of the garage at every use. My CR purchase coincided with radical wash regimen changes (foam gun, CR, Air Force Blaster), so I'm not sure how fair a judge I can be. I did get a few spots yesterday when I wore out my cartridges, so I guess it's an essential part of the process :nixweiss. I'm not sure how I'd do if I just had soft water outside, and was blowing dry. One of these days I'll mess around with my plumbing to get my soft water to my driveway faucet.



Their "new" system does look a little better, no more brass fittings, and no having to plug in the quality light. I had a couple leak issues with their cast fittings that were supplied with mine.
