RV-MODS it's absolutely the best source for very high-quality D-I resin. I would not shop anywhere else for D-I resin except RV mods for their exceptional customer service and very fast shipping.

GMGreg M.Verified buyerI purchased the DI Pro D50 in June of 2018. I use the system several times a month to wash my (garaged) car and also to wash windows. My TDS reading is around 185. I don't think I've ever used this system in bypass mode. I rinse, foam and wash my car with deionized water. My Krazle pressure washer is set at 1.6 GPM. I have changed the resin 1 time and just ordered a refill. Over the years it's unbelievable how inexpensive these systems from RV Mods work. I honestly have never used RV Mods customer service and I believe it's just because their products don't break and the system I have going on 7 years old is as good as new. No valve issues, no water leak issues, absolutely nothing. Buying this system was probably one of the best decisions I've ever made.
+ 2THTheodore H.Had mine fall over and break, and was in a hurry for a replacement to fix my tank. Ordered and delivered within a week! Perfect fit and timing
CVCharles V.Verified buyerGreat Product Fast shipping
BWBilly W.Verified buyerService was quick and package was sealed with fresh moist resin . My filter only uses 1/2 cu. Ft. So I split the 1 cu. Ft. In half weighing it. I rapped up the remaining resin and sealed it tightly. I Put the date on it and in 6 months I will change it out. My water is at 175 and with the Pro 50 C my water is 0. My unit was purchased in 2018 , I wash two vehicles every week. I’m very pleased with my purchase. Tip: keep the water pressure low going to the unit, otherwise you will over run the filter.
PNPaul N.Verified buyerVery good service,I ordered online on Sunday and by Wednesday the same week I had the product. I used to get it from DI Rinse and would have to order it as soon as I changed it out because it would take 6-8 weeks to get it from them.I will be ordering from here again.Thank you

Is there a way to drain the water and save the resin for winter storage?
Once the resin has been covered with water it's best to leave it covered, Once you drain the water from the resin, The resin will go moldy.
Can these be used/modified to work in a Waterdrop filter system with 20" filter housings?
These were made for the CR Spotless only. If your waterdrop system has the same head units as the CR Spotless. Then yes they will work. If your system isn't identical to the CR Spotless system then, No it won't.
Will this system work with my Active 2.3 pressure washer? I saw that the max recommended flow rate is 1.8gpm but was wondering if it will still work.
Hi Joe Yes it will, we recommend lower inlet pressure to extend the life of your resin. The higher the through put the longer your resin we last. Hope this helps
Any ETA on when this will be back in stock? Showing out of stock 11/19/24. I need to order and replace my resin. Thanks!
We are just checking the physical stock we have in stock as we think the on line stock figure is incorrect. We will confirm this later on today These are now back in stock
I have the CR spotless with the bypass valve to use tap water to rinse and then DI water for final rinse. Will this conversion allow for use of the DIC20 lids (Bypass filter attached)?
Providing that the blue cylinderrs are CR Spotless then yes they will.
Hi guys. Who is the company or manufacturer of your DI spot free system? Thanks Rick in California
We manufacture our own products.
SO for the DI-120 guys who want to do this conversion, I'm guessing for the left over amount (more then the duel setups) if be best to put it in an air tight buckets with water to it for storage shelf life?
Totally wrong. Keep the spare resin as airtight as possible and store in a cool dark place until needed.
It stays on 000 before and after inserting into test water. I've watched video and read instructions. What am I doing wrong. Thank you
Are you wishing for the resin to be used up quicker. 000 means 100% DI water !
Is it advisable to use a 1.8 gpm flow restrictor on the inlet side of the system? If so, it there a particular flow restrictor you recommend?

My water is about 310 ppm from my tap. Is there any pre-filters you can recommend that may possibly extend the life of the resin?
Thank you. We aim to please.
