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.

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.

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.

The water softener works great. We are in Florida, so the water is super hard. My wife was having trouble with her hair for so long. She noticed a huge improvement after her first shower using the softener. It’s super easy to use, easy to set up, and easy to regenerate. I absolutely recommend this for any RVer

Highly recommend this softener. We travel in RV and is very helpful with water. In different parks. Makes the water so much softer and even tastes better.

Being an RV'er in the southwest I stumbled on THE hardest water there is and couldn't survive another day without a softener. ALL my research pointed to the On The Go brand so I ordered up and had it in 5 days during Christmas rush! DO YOUR RESEARCH! Just running water through a softener wont solve all your water problems. Where I'm at the water is salty well water so a softener accentuates this but stripping Mg/Ca and replacing with Na... GREAT for bathing and cleaning but no way can I drink it! Thoughts vary on drinking soft water but this water is too salty to determine if I can. Took a few minutes to hook up and flush. Then let run through your plumbing. IF you're RV'ing in the SW or other places with very hard water note you can have build up in your plumbing that will take some time to clean out with soft water. May need a vinegar rinse to really clean out. Over all my research indicated using soft water is great for RV plumbing and especially the water heater and this is your best option for a portable version. Get this size for 1 or 2 people.

We installed this in our 5th wheel 43ft Montana. We have the three cartridge water filter and added the water softener and it has made a huge difference in our water Our skin is not dry after showers and better for our clothes. We use for over a month before changing out the salt. Ours uses Morton salt and easy to clean. We are very pleased.
