We had our plumber install this expensive WATCO water softener, then decided to go with a whole-house alkaline water system. (Not because of any deficiency of the WATCO system; just because.) As such, this WATCO system doesn't have a ton of usage. We had the plumber disconnect it and it's been in our warehouse ever since. It was working perfectly when removed from service, but I have no way to test it now. As such, it's sold as-is, but I have no reason whatsoever to assume there's anything wrong with it.
Other items shown are not included. I forgot to photograph the model number of the WATCO unit, but can provide it upon request.
