PRO+AQUA Portable RV Water Softener, 16,000 Grain, Pre-Filled high-Capacity Resin, Neoprene Shield, w/connectors - Protects RV Water Systems from Hard Water deposits, Build-up, Corrosion, and Scale

We replace this filter in our RV annually. It does a great job for our 2019 Redwood. We were so glad to find this through Amazon at a much better price than offered at Camping W***ld. We plan to keep the RV for the foreseeable future, so will be ordering again! The water where we camp in Colorado for the majority of our time is actually very clean, so if we camped in areas where the water was not so clean, we might have to replace it more often. It does the job!

Easy setup & works great!

I have been full time in our 5th wheel for almost 3 years now. I had well water for 30 years when we lived in real house so I am quite familiar with water softeners and how they are supposed to work. This unit works well but we use a lot of water and need to re-gen about once a week. I have been testing daily with test strips so I know when I need to do a re-gen. We probably wash 2-3 loads of laundry every day. This seems in line with what I was expecting since we had our whole house softener set to regen every 2 weeks whether it needed it or not. Not sure how some people claim they can go 6 weeks? Doesn't seem practical to me unless they shower only once a week. I did find the good old Morton water softener pellets with iron reduction work best and probably 1/10th of the cost of table salt. I put a filter full in Hefty bags so I am ready to go. The Morton 40LB bag will last 3 months. $8 I use a clear filter similar to the one Pro Aqua sells since Amazon was out of them and fill it full for a regen. Then lay it on the side so it mixes the salt better. I use a standard hose verses the skinny one they supply and just run it with a very slow stream. Takes about an hour. I always fill my fresh water tank before hand so it causes no issues with the wife. We have been using it for a few months now and really like it. I suspect we will get 2 years use before we need to replace the resin. Overall a very good solution for mobile or temporary applications with limited space. All the fittings on my system worked just fine. I think you just need to know how to use a washer properly unless there is a defect.

it came quickly and fits my system and works well

Ease of installation
