Water Heater Repair in Louisville, CO
More than half of Louisville's homes were built in the 1980s and 1990s, so many are now on their second or third water heater. If yours has stopped, is leaking or makes odd noises, call and get a plumber out.
What shapes water heater trouble in Louisville
A house on its third water heater
The median Louisville home was built in 1991, and about 54% went up between 1980 and 1999. With tanks lasting roughly 8 to 12 years, a 1991 house may be on its third heater by now.
Each swap is a chance for small problems to pile up: mismatched fittings, a vent pipe that no longer lines up cleanly, a shutoff valve that won't fully close. A good plumber checks all of that, not just the tank.
Louisville Reservoir and Marshall Lake
The City of Louisville's 2026 water report lists two surface water intakes, Louisville Reservoir and Marshall Lake. The city treats the water before it reaches homes.
Boulder County cold
NOAA's Boulder station, the nearest we use, averages about 138 nights a year at or below freezing and January lows near 22°F. That's milder than towns farther east, but it still means months of colder water coming into the tank.
Safe steps for Louisville 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? Xcel Energy serves Louisville. Leave the house, call 911 from outside, then Xcel Energy at 800-895-2999.
