What that means for a Marana home
On the USGS scale, water above 180 mg/L (about 10.5 gpg) is very hard. Marana's published range of 8 to 18 grains per gallon (130 to 300 ppm) runs from hard to very hard. Hard water leaves calcium behind wherever it dries or heats up: the white crust on faucets and shower glass, and the scale you cannot see inside a water heater, a tankless unit or a dishwasher.
Marana Water runs several separate water systems, and its own hardness table shows them ranging from 56 to 300 ppm, so which system serves your address matters more here than almost anywhere else in the area.
Which system fits Marana water
Our Soft-Tec® salt-free system is built for city water. It needs hardness under 75 gpg, water pressure between 40 and 100 psi, and essentially no iron, sulfur or manganese. Marana's published range tops out at 18 gpg, well inside that limit, so most homes on city water here are a fit. It keeps scale from bonding to your plumbing without salt, without wasted water and without electricity, and the minerals stay in your drinking water. How Soft-Tec works.
A salt-based softener is the better answer for well water, for water outside those limits, and for anyone who specifically wants the hardness minerals taken out. We install those too. The Hybrid Water Softener.
Marana Water disinfects with chlorine (calcium hypochlorite). Stage two of our whole-home system is a coconut-shell carbon filter, designed to reduce chlorine and chloramine taste and odor.
