Water Heater Services Across Tempe
Tempe was largely built out before most of the East Valley started growing. Central and north Tempe date mostly to the 1950s through the 1970s, and south Tempe filled in during the 1970s and 1980s, so many homes have been through several water heaters, often in the same interior closet or garage corner the builder chose. Tempe’s 2025 water quality report puts average hardness at 12.3 grains per gallon, with individual readings from 10.4 to 32.6 across the system. About 79 percent of the city’s water comes from SRP’s Salt and Verde River supply, with groundwater wells and Colorado River water making up the rest. Add the rental density around ASU, where water heaters see heavier daily use than in a typical household. We have completed 1,800+ home service jobs in Tempe.

Water Heater Questions from Tempe Homeowners
How hard is Tempe’s water, and why does the range vary so much?
Tempe’s 2025 water quality report lists an average hardness of 12.3 grains per gallon, but individual readings ranged from 10.4 to 32.6. Tempe blends several sources: most of its water is SRP surface water from the Salt and Verde Rivers, supplemented by groundwater wells and Colorado River water. For a water heater, the practical point is that scale builds faster in some parts of the system than others, so if you hear sediment noise or see scale on fixtures, flush more often than once a year.
I own a rental near ASU. What should I know about the water heater?
Plan for heavier use. A house with several adult tenants can draw far more hot water in a morning than a typical family, so size the unit to the number of bathrooms and occupants rather than the old tank’s label. Flush it at least once a year, test the temperature and pressure relief valve, and make sure a closet or attic unit has a drain pan and line. A leak detector or automatic shutoff valve is inexpensive protection when no one reports a slow drip. Our phones are answered 24/7. For true emergencies we dispatch a technician between 6 AM and 7 PM. On permits: Tempe City Code Chapter 8, §105.2 exempts replacement of a water heating appliance of the same type, fuel source and location, at equal or lesser rating, in detached single-family, two-family and townhome dwellings. Arizona’s owner-builder exemption does not cover a property you rent out, so a replacement in a rental needs a licensed contractor.
Does SRP offer a rebate on heat pump water heaters in Tempe?
Yes, for SRP customers. SRP currently offers a $500 rebate on an ENERGY STAR heat pump water heater with a Uniform Energy Factor of 2.8 or higher that replaces an existing water heater and is installed by an Arizona-licensed plumbing contractor before April 30, 2027. The account needs more than a year of SRP residential service, new construction does not qualify, and the application is filed online within six months of installation. Your electric bill shows which utility serves your home. Confirm current terms with SRP.
My older Tempe home is all-electric. What are my water heater options?
There are three. A standard electric tank is the simplest replacement. A heat pump water heater uses far less electricity for the same hot water, but it needs space and airflow, which suits a garage better than a small closet. An electric tankless unit sounds appealing, but whole-home models draw a very large current, and many older Tempe homes do not have the electrical service to support one without an upgrade. For income-qualified households, the state’s Efficiency Arizona program covers heat pump water heaters that replace an existing electric unit.
What should I do if my Tempe water heater starts leaking?
First, shut off the cold water supply valve at the top of the heater to stop more water entering the tank. For a gas unit, turn the gas control to off; for an electric unit, switch off its breaker. If water is spreading, open a hot water faucet and use the drain valve with a hose to lower the level in the tank. Then call us. A leak from a fitting or the relief valve can often be repaired, but water coming from the tank itself means it needs to be replaced.
