Review: Great unit. Don’t blame small softeners for issues you have if yours is extremely hard water. - Been using this in our RV throughout the south and west for a couple of years. Having the brass fittings gives piece of mind for durability and minimal leaks at fittings. Works great on all water so far. Even works in Yuma AZ where the hardness is around 50 gpg. Easy to set up and easy to recharge. And contrary to all the whiners out there, it’s not the softener’s fault when you have extremely hard water and you quickly have to recharge the unit. Read the info from water quality experts. Resin is resin in general (well, there are 2 kinds, but this has the standard c-100e). If you have really really hard water like Yuma, you are going to have to recharge often. It’s simple math. The unit can remove 16,000 grains. If your current water has 50 gpg to be removed, 16k divided by 50 is 320 gallons of treated water. That’s all you are going to get out of a recharge. For a hour old of 2 with washer and dishwasher, that’s about 3 weeks for us. If you are using 300 gal per week, plan to recharge weekly. If you need more capacity, no other 16k grain unit is any better, you need a larger unit (or 2 of these in series). And, if, like Yuma, the water tastes salty even after treatment, it’s not the softener’s fault, again, it’s the specific minerals in the source water…no other softener is going to do better (maybe reverse osmosis…but I’m told those use over 9x the water you get out of them to recharge which is waaaay too much water wasted to be of any real use in an RV system). In short, these are quite nice softeners…just don’t blame them if your source water is way beyond normal hardness and you have to recharge frequently…it’s simply the amount of resin that fits in these small tanks (and the hardness of the source water) that drives the recharge frequency.
Review: Why didn’t I buy this 10 years ago? It changed me. Worth twice what you pay. - Outstanding product. Outstanding results. From just about the hardest of hard water to soft and smooth. My beard has not stopped thanking me after my first shower. Dishes are clean. Sink stays polished. It’s soooo so easy to set up. As for it durability. It looks like it could take a bump or two. Moving it around. It’s not light but very manageable for the double standards. Rope handle makes it easier. As for regeneration, I’m not there yet, but I installed a gallon counter to see how far it gets. By the gallons not by the days. Although average should provide a pretty accurate look at it overall performance. Honestly should have had 10 years ago. New tankless water heater required it. Well if you want it to function properly without buildup. Overall I looked at most of them. This one was worth the extra coin and shipping was fast and free. The best way. Press buy! It will physically change your life. posted. 10/6/25 Update to be posted upon registration. With stats.

## Questions & Answers

**Q: Why is it that you can not send this to ZIP 84009?🤔**
A: They sent me mine, I have that exact same one and we live in lot 19

**Q: What are the product dimensions?**
A: It’s in my Motorcoach. The next time I am there I will get dimensions. Works great! I also bought 2 additional filters and connected to Motorhome.

**Q: How long does the resin last before it need to be replaced? Mine stopped working after one year.**
A: Resin has a shelf life of 7 to 10 years BUT.. If you go too long before performing the regeneration process, a few things may happen: your unit may not last very long, or, after the regeneration process, the strips will not test between 0-3 GPG at the output of the softener. This can easily be corrected by performing a special regeneration process. 

Capacity of a Water Softener
How many gallons a softener will approximately make depends on the hardness of the water source and your water usage. To figure out the approximate capacity of your unit, take the grains of the unit (Standard 8,000/Double 16,000) and divide that by the grains per gallon (GPG) of the water source.

Standard Softener 8,000 / 11 GPG = 727 gallons 8,000 / 58 GPG = 137 gallons
Double Standard Softener 16,000 / 11 GPG = 1,454 gallons 16,000 / 58 GPG= 275 gallons

**Q: How long can it be stored without doing all the prep needed for storage?**
A: By mark on June 14, 2023

### ⭐⭐⭐⭐⭐ No more hard campground water!!
*by D***Y on December 8, 2025*

I absolutely love this water softener! I’m used to soft water at home and I purchased this for our Fifth wheel camper! My husband thought I was crazy until he took a shower! Now campground water is no longer harsh on the skin and hair! Looooovvveee IT! So easy to use and set up! And easy to regenerate. So far the quality is worth the price! It is a little bulky but we just set it in the back of the truck bed in front of the hitch for travel.
