In Commerce City, a water heater that loses heat or leaks usually needs one component replaced, such as an element, thermostat, thermocouple or valve, and a plumber can generally finish it in a single visit. A leaking tank body means the heater must be replaced. Call the number on this page to be connected with a local plumber in Commerce City.

Local conditions in Commerce City
Commerce City's water and sewer come from South Adams County Water and Sanitation District, which calls itself the largest combined water and sanitation district in Colorado. Its tap water is a blend of district well water, from eleven alluvial wells along the South Platte and three deep Arapahoe formation wells treated at the Klein Water Treatment Facility, and treated surface water bought from Denver Water. It is disinfected with chlorine. SACWSD does not publish a hardness number, but blended groundwater can leave mineral deposits, so a plumber checking a noisy or slow heater will usually drain some water to see what has collected.
The city has a wide range of housing, from older neighborhoods that grew up after industry arrived in the late 1920s to newer subdivisions in the north. That spread means heaters of every age and installation style, from basement units to garage installs.
The city's Building Safety Division lists replacing a water heater as work that can need a building permit; permits and inspections run through the eTRAKiT portal, and Building Safety at 303-289-3790 can confirm what your job requires.
Repair or replace
| What you see | Repair is likely when | Replacement is likely when |
|---|---|---|
| No hot water | An element, thermostat or thermocouple failed | The tank is also leaking |
| Not enough hot water | A lower element or dip tube is bad | Sediment has ruined the tank on an older unit |
| Leak | The drain valve, relief valve or a fitting is the source | Water is seeping from the tank wall |
| Rusty hot water | The anode rod needs replacing | The tank itself is corroding |
Signs to act on
- Popping or rumbling from the tank
- A pilot that keeps going out
- Moisture under the heater or rust on the fittings
- Water from the relief valve discharge pipe
Seasonal notes
Winter is when tired heaters give out, because colder incoming water makes them run longer. A tank that is slow to recover in fall is a good candidate for a check before the first hard freeze. For a water main break or loss of service, SACWSD takes emergency calls at 303-288-2646. For a gas smell near the heater, leave the house first and call 911 and Xcel Energy at 1-800-895-2999 from outside.
