Hard Water in Phoenix-Area Homes: What Homeowners Should Know

How hard water can affect plumbing and appliances, and what you can do about it.

What hard water is

Hard water carries dissolved minerals, mainly calcium and magnesium. Much of the Phoenix area has hard water, and it can leave scale on fixtures and inside appliances.

Where you'll notice it

White crust on faucets and showerheads, spots on dishes, and reduced flow from aerators are common signs. Scale can also build up inside water heaters and appliances that use water.

What helps

Clean aerators and showerheads regularly. Follow your water heater manufacturer's flushing guidance. Some homeowners install water softeners or filtration. A plumber or water treatment specialist can explain the options and upkeep for each.
