I'm looking into getting a water softener for our house. We have recurring problems with staining and deposits in the showers, toilets, etc. I had the local Culligan dealer install a demo unit just to see what the soft water would be like. So far, it seems like it may be an improvement, and the family seems to like it. But, the water pressure is reduced by the unit. The pressure seems to be slightly lower when only one faucet is turned on. However, it is drastically lower if a couple of faucets are running. Is this expected from a water softener? Or is it related to this being a "demo" unit? While I've decided I need a softener, I haven't settled on Culligan yet.
Thanks, Dave
