EPCOR water in Anthem at 15-20 gpg is hard water typical of North Valley deep well sources. Every Anthem home needs a scale management strategy for its water heater — whether tankless or tank.
Anthem North Valley location at the base of Daisy Mountain makes it the coldest residential community in the Phoenix metro. The Daisy Mountain Veterans National Memorial area and the I-17 corridor experience overnight lows that occasionally approach freezing in January and February.
