Ya, the only crappy thing is the filter resins will exhaust more quickly than usual. But our water here is overall very good. My source TDS was testing in the 130-160 range (taken readings last month), but i'm sure the added Chlorine/Chloramines will up that a bit.
Luckily it's a new unit that only made about 30 gallons total so far, so there's a lot of life left in these guys
Good advice though.
