I bought one online, back before that brand that said no more drop shipping our water softeners without on-site support. Speedbump I believe it was the brand that your buddy with the RV was selling out of his RV on all the forums.

I just looked, it has no nameplate on it, it was a fleck, flack, clack... something... well reported as the "best".

I bought it from Ohio Pure Water Ohio Pure Water - Water Treatment Equipment and Accessories

It didn't seem to work right (of course I didn't read the manual), sent them an email, technician spent probably 30 minutes during his evening, probably 8:00 PM walking me thru the settings.

I would have no problem using them again.
