This system is so nice! Customer service was extremely helpful and responsive. The shipping was also very quick. I am using the spot free DI tank for my final rinse after washing my SUV and it drys with no spots. I have also been using it to wash my windows at my house, i spray the windows with the hose or power washer first to get all the dirt off, and then blast it with the DI water so it drys spot free. Saves me from having to get up on a high later to wash the windows or hire someone to do it. We also have solar panels at our house, and i have been using the DI water to clean our panels. Just make sure to do it at dusk or dawn when the panels arent hot.

RV Mods
I only use the resin from RV-Mods. I have had no issues in terms of length of service.
CSCarl S.Verified buyerThis company has fantastic customer service. I know of another company that sells these DI water systems and I do business with them as well. They are a great company, with fantastic customer service. RV Mods is better! Better pricing, faster processing and shipping, and fantastic customer service. I hope you don’t make a mistake and shop elsewhere. Hopefully you will trust that even though these products may be found elsewhere, RV Mods should be the company you shop with. They can’t be beat, and the other company is no slouch! Trust in RV Mods and they will prove me right!

What are the dimensions of the tank?
8" x 24"
I’m looking at the Pro-200 and wondering if this is your largest unit. I’d like to use this system on my home windows but want to make sure it’s large enough to handle the entire house. Thanks.
Yes the Pro 200 is our largest unit and will easily cope with your whole house.
Does the Resin refill have a use by date or expiration date?
The resin doesn't have a use by date, but you should start to use it no longer than 12 months after the purchase date
What will happen ifi use a 2.6 gpm pressure washer
You will use up your resin quicker
So you just use loose resin in the blue cylendar instead a the cartridge ? Thanks
Yes, with the conversion tubes fitted
how much resin will i need to do the conversion?
The description says increase output, does it mean it increases the CR’s flow rate? Or just how efficient it uses the resin?
Do you sell a cart that this can be placed on? If not do you have a recommendation for one? Do you sell a pressure regulator that can be adjusted to 2 gallons per minute?
No we do not have a cart for our tanks. Lowes sell an inexpensive one.
What is the process to store this over the winter after summer use?
As long as the resin is still covered with water from the previous use (never drain the water after use) . You simply need to store the tank somewhere that doesn't freeze.
If you have a 0.5 cu-ft system, can you purchase a 1.0 cu-ft resin refill, and store the unused 0.5 cu-ft for a second refill?
Yes, you can providing that you store the remaining resin in a dry ,cool, dark location and as air tight as you can get it.









Love to hear it, thank you for your kind words!
