With health/family problems I would expect money to be important. You can actually get an industry standard high quality softener for thousands less. You buy Hague , there is only one dealer you can go to for service and parts.
What I sell is the same as would be found in a fast food place etc. etc., you don't find Hague there, only in residential. And there are many dealers to buy parts from.
It takes 30 minutes to assemble the average sized softener and then you can hire a plumber to install it.
