I am a repeat customer - purchased my first DI Pro 50 in 2022 for my dock and then added a second Pro 50 for the other end of my dock in 2024. I will be buying a third Pro 50 this week to use for my cars. I just want to say what incredible products you all sell - never had any issues with the units except last year one of the top pvc heads cracked due to a rare freeze here in Florida (Glenn directed me to the replacement part last year). And can you believe that the first DI Pro 50 I bought in 2022 is still working perfectly with the original resin - that’s amazing! I highly recommend RV Mods Spot Free Finish - Amazing products!

Spot-Free Finishfrom RV Modsawesome product, makes draining the resin a breeze.
JBJon B.Verified buyerWe noticed that this was a vital part of the process so glad you are using as intended!
Rvt 24 ..from RV ModsThis 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.
JSJustin S.Verified buyerHey Justin, what a great review we couldn't have said it better ourselves!!
Rvt 24 ..from RV ModsI only use the resin from RV-Mods. I have had no issues in terms of length of service.
CSCarl S.Verified buyerThanks for your loyalty Carl!
Rvt 24 ..from RV ModsThis 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!

Does this use reverse osmosis
Hi Keith, no this does not, it uses a mixed bed resin that removes the TDS from the water. It is much faster and less wasteful than reverse osmosis.
What are the dimensions of the tank?
8" x 24"
How to,get a promo,code and what product number from Lowe’s for cart to support tank
Hi Steven, we believe our systems are incredibly well priced vs our competitors so do not do promo codes, the price of shipping is also included.
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.









Hi Ed, amazing to hear that you have 3 units and are getting use out of them all! Thank you for the review, we aim to be there for our customers when thing like that happen and stock everything thats needed to get you back up and running, we hope you enjoy your next system as much as the first two!
