Water Heater Repair in Firestone, CO

What shapes water heater trouble in Firestone
Soft water and the anode rod
Firestone's 2026 water report gives an average total hardness of 33 mg/L and notes that under 60 mg/L is considered soft. The water comes mainly from Carter Lake, with some from the St. Vrain system and a well.
Soft water leaves little scale, but it tends to use up a tank's anode rod faster. Once the rod is gone, the steel tank starts to rust from inside. Rusty hot water or a rotten-egg smell are signs to have it checked.
The newest housing in the area
About 89% of Firestone homes were built in 2000 or later, more than any other town we cover on the Front Range. Many water heaters here are original, and the ones from the early 2000s are now well past 15 years.
Newer homes often have power-vent or high-efficiency gas heaters. If yours has a fan on top or a display, mention it when you call.
Cold nights on the plains
The NOAA station at Longmont, west of town, averages about 178 nights a year at or below freezing, with January lows near 14°F. Colder incoming water means longer run times, and that's when a weak part fails.
Safe steps for Firestone homes
- Leaking? Close the cold water valve on top of the tank.
- Turn off the gas valve or the breaker for the heater.
- Gas smell? If you smell gas, leave the house and call 911 and your gas company from outside.

Is Firestone's water hard or soft?
Soft. The Town of Firestone's 2026 report lists an average total hardness of 33 mg/L, and under 60 mg/L is considered soft.
Why does my hot water smell like rotten eggs?
It's often a reaction between the tank's anode rod and the water. Swapping the anode for a different type usually fixes it. Have a plumber check it.
My heater has a fan on top. Is that normal?
Yes. That's a power-vent heater. It needs electricity as well as gas, so a tripped breaker or failed fan can stop your hot water.
How old is my water heater?
Look at the label on the tank. The date is often printed there, or coded in the first digits of the serial number.
