I also have a Jayco 5W I have parked at a campground since I bought it new. The campground has well water for our use. Most of us have filters which are changed monthly do to the rusty & hard water, and then a few of us have portable water softener for RVs. The question is from the water hookup to the RV, which should go first. The filter or the softener, I have tried it both ways and not sure which work better. If i have the filter first, i am replacing it more often then if it comes after the softener. not sure if there is much difference in the output for internal use. And yes I know I will get answers both ways, but just wnated to see what others migth think. It does lower the pressure big time, but what a difference in water quality. I know using them both also helps the water lines in the RV.
