help me size a softener .. industry standards seem off??
I live in northern NJ and water is hard. Not horrible bit definitely noticeable. I bought test strips and while those aren'ts super precise, the color most closely resembles about 7-10 grains. I'm on well water and don't know the iron content at this point but it's not noticeable in the house - no red rings anywhere.
In any case, I read a bunch of things online on sizing and all of them give you 75 gallons per day per person as a benchmark. I have 5 people in the house and we do more than a fair share of running the dishwashwer, washing machine, long showers etc. However, I averaged the water use for the last year based on water meter readings and it works out to about 200 gallons per day.. that's way lower than the "industry average".. so i'm wondering if I'm wrong somewhere or if my count might be off somehow.
If it IS 200 per day, what would be a good option for softening?
Also, I personally don't like the 'slimy' feeling of ultra-soft water. is there a way to control how soft it is? meaning, is that something a softener can do, or do they just extract as much mineral content as is available? does anyone use mixing valves to control the level of "softness" or anything like that?
