Not sure if anyone has ever tried this scenario …?
I have been cleaning windows & carpets for over 25 years.
I own a Butler carpet cleaning system which has its own 110 gal fresh water tank.
I am thinking of utilizing the 110 gal tank for holding di water and when needed running it through the carpet cleaning system to clean windows.
I can adjust down the pressure and have 150’ of hose to easily maneuver around customers home with out hassles of connecting and using the customers water supply,
Only downside is of course the cost of running the system which runs off the vans engine but if the end result works it would be well worth the additional costs.
The big question is how much impurities will be picked up in the process of running the di water thru the complete system.
Of course I will descale the system the best I can.
Any one have comments or real world experiences?
Thanx, Scott.
It will probably pick up residue of carpet leaning chems.
A good descale and running DI water through to rinse a few times may help.
I have heard of folks using DI for carpets, but never heard of using
the same machine for windows. Great idea if it works. You could also heat up
you water for WC.
Hi Mat,
Thank you for your input.
You think heated di water would be beneficial over regular temp?
Im very familiar with the Butler. I worked off it for a few years. I drove to mass. To go pick it up with my friend who bought it.
It’s a good question will the water stay pure. Will normal water that hasn’t been filtered leave behind setiments . I don’t know the answer to that.
You would need a separate pump to pump the water out to get to your WFP.
What’s your TDS there ? You could always go with a couple of 1/2 cube Di tanks. Tied in together.
I got your pm. If your going to be stationary I like the Di tanks. If your going to need to be mobile I like the Unger Di tanks.
Too much pressure, running it through the Butler pump. You could use the tank, but I would plumb it and run it off another pump. I think the CC pumps will only run down to 200 PSI. That’s way too much for windows.
I also wouldn’t want to hassle around descaling and cleaning everytime I had a window job. Another reason to plumb a dedicated line for windows and WFP.
This is an interesting thread. Curious to know how many guys and gals have put much thought into the fact that TDS meters do not accurately measure total dissolved solids. They measure the electrical conductivity of the water coming out of your DI tank. There are other industries out there that work with the chemistry of water. Their insights and products would be quite valuable to our WFP community. The chemistry and electrical properties of water has always fascinated me. And I truly do believe that is where this community is moving. I once again would like to call into this discussion one of our leaders;…Perry Tait. Also, here is an interesting edu site I found on water. Water Science School | U.S. Geological Survey

Thanx for all of your inputs…
maybe I will just use di water all the time for cleaning carpets as well so I wont have to descale all the time …
How much extra would I really be spending on using di water while cleaning carpets?
We do much more window cleaning than carpet cleaning so maybe that extra $5 or $10 per carpet job for the expense of di would be worth it?
I’m not as smart as you , and I won’t pretend to be , but I really believe they don’t need to be accurate. As long as it tells me at what number my windows will start spottung
So the true measurement might be 2ppm an the meter that we use might say 4ppm. With my meter it tells me I start spitting @ 5ppm. That’s all that matters.
I think 
If I explained this wrong you know what I’m getting at though . Or is this pea brain of mine just off track.
I really believe all that matters is when the ppm starts to spot with any measuring gizmo. One measuring instrument might be different from the other an be more accurate , but as long as I know whst Ppm the inaccurate one should be at its all good
Majestic,
You have just proved what I have always believed. That intelligence is defined by imagination not the retention of discovered knowledge. I agree with you. Keeping your TDS around 1 to 3 should be good. Even if it is inaccurate. My big question right now is only how much silica can be in the water without showing? Cuz it shouldn’t show on a conductivity meter.
Thanx for your thoughts!

Filter the water with dI after it comes out of the tank.
How much it costs, really depends on your TDS and the filtering system you use. I can’t tell you off hand what it may cost you.
You will be the one to know too, how many gallons you typically use per average room. I did a very thorough flush so I used to use quite a bit of water for a 3 room clean.
All in all though, I can’t imagine it will raise your costs very much, and it will clean better to boot. RO/DI water give a superior clean to even softened water. It could be a good selling point for you.
Yes that’s what I was thinking as well …
utilizing pure water for carpet cleaning probably doesn’t make much of a difference in the end but it would not be a lie by stating that pure water will leave carpets cleaner.
I am thinking of purchasing the 1 cubic foot WCR DI Tank which I think would be the best bang for my buck in this scenario … if I do find that its jus not clean enough for window cleaning I can still utilize the di tank as intended.
I believe the cat pump on my system will go down very low … I do know in the past that I have used it under 100 psi at times … I will check it out today to see exactly how low of a pressure I can go …
Just remember that 1 cubic ft will be a bear when you have to change the resin. If you could fit 2 half cubes , an tie then in together. That wouldn’t be a bad way to go. Just food for thought !!!t
A 1 cube does fit nicely somewhere though if your limited with space .
Like was suggested, if you have the room for two half cube tanks, maybe that is a better idea so you aren’t breaking your back when you change resin.
Also, what is the TDS of your area, or at least where you will be sourcing water? Will you need to use an RO too? How many gallon a week, of water, are you going to be using?
Before just ordering something you should talk to @Chris or John Lee. These guys are the experts with something like this.
As unnecessary as spot free glass. 
Yes ty
Thank you
DI tanks to remove the ions and an RO system to remove the silica. That sounds like a plan.
