Water Heater Repair in Longmont, CO

Is Longmont's water easy on water heaters?

Yes, more than most. The City of Longmont's water report describes its water as soft, typically 1 to 2 grains per gallon, roughly 19 to 25 ppm of total hardness. The supply comes from North and South St. Vrain Creeks, stored in Ralph Price Reservoir, plus Colorado-Big Thompson water by way of Carter Lake, treated at the Wade Gaddis and Nelson Flanders plants and disinfected with chlorine. Soft water means far less scale on electric elements and less sediment piling up on gas burners than in hard-water cities. That does not make tanks immortal: anode rods still wear down, valves still fail and some sediment still settles. But a Longmont heater that rumbles loudly or runs short is worth a closer look, since hardness is less likely to be the whole story.

Does a water heater job need a city permit?

For replacement, yes. Longmont requires a permit for any changes to electrical, gas, mechanical or plumbing systems, and lists water heaters by name among work that needs one. Permits go through Building Services at the Development Services Center on Kimbark Street. A repair that just replaces a failed part inside the existing heater is a different question, and the plumber can tell you whether it needs anything filed.

How old is my heater likely to be?

Longmont's homes span more than a century, but census estimates put the median build year at 1991, with about 37.1% of homes built before 1980. Many houses from the 1990s and 2000s are on their second heater, and some still have tanks from the 2000s or early 2010s. The label tells you exactly. If the heater is under about ten years old and only one part has failed, repair usually makes sense. If it is older and leaking from the tank, rusting at the fittings or needing repeated repairs, a plumber will likely recommend replacement.

A local note on gas and sewer

Xcel Energy is Longmont's natural gas utility. In a gas emergency or if you smell gas, leave the house first, then call 911 and Xcel Energy at 1-800-895-2999 from outside. And if a water heater leak has you checking other plumbing, remember that in Longmont the property owner owns and maintains the sewer service line from the house to the city main.
