I see there are portable water softeners for RV's now. They seem a little pricey but not out of reach. Does anyone have any experience using one? Are they worth the money?
I’ve used one for years and they are quite effective. Regeneration is easy using table salt. Time between regen depends on the size of the unit and the hardness of the water. In AZ we averaged weekly regen. Currently using the On The Go unit which has a wide mouth opening making the salt addition easy.
