Parker's homes are young, with a median build year of 2004, so many are already on their second water heater.
Parker water heaters at a glance

What Parker's water does to a water heater
When water is heated, the calcium and magnesium in it drop out as sediment and settle on the bottom of the tank. The burner or lower element then has to heat through that layer, so the heater runs longer, pops and rumbles, and wears faster. Parker Water's water averaged 108 mg/L of hardness in 2025 (about 6 grains per gallon), ranging from 34 to 206 mg/L across 298 samples. Moderate scale. A yearly flush and an anode check every few years keep a tank close to its rated life.
Young houses, second water heaters
Only about 1% of Parker's homes are older than 1970, and the median home dates to 2004. A tank water heater typically lasts about 8 to 12 years, so a house from the 2000s is likely on its second heater, or due for one. Most of the town gets its water from Parker Water & Sanitation, but some subdivisions are served by Cottonwood, Pinery, Stonegate, Compark, or Meridian; your water bill names yours.
Repair or replace?
Under about eight years old, with a failed part like a thermocouple, gas valve, heating element, or thermostat, a repair usually makes sense. At about ten years or older, or with any leak from the tank itself, replacement is the better money: a leaking tank can't be fixed. You get the price before any work starts, and most replacements are done the same day they're quoted, with the old unit hauled away. A replacement is also the time to check whether you need an expansion tank (when one is required).
Gas or electric, tank or tankless
We repair and replace both gas and electric water heaters, standard tanks and tankless units. Tankless works well at this hardness. Descale it about once a year so scale doesn't choke the heat exchanger.
At about 5,870 feet (Parker's USGS reference point), a gas water heater has to be rated for the altitude, and a tankless heater set for it at installation. That's above 5,400 feet, where Rinnai and Navien change their tankless settings, though elevations vary across the city. What to check at altitude.
Make the next one last
- Flush the tank once a year to clear sediment
- Check the anode rod every few years
- Descale a tankless unit about once a year
- Know where the cold-water shutoff on top of the heater is, and how to turn the heater off, before you need to
