How we diagnose gas water heater issues
Gas supply & pressure check
We verify gas supply pressure and line sizing are adequate — undersized lines or low pressure are a frequent, overlooked cause of ignition and burner problems, especially after other appliances were added to the same line.
Thermocouple & control valve testing
A failed thermocouple or flame sensor is one of the most common reasons a pilot won't stay lit; we test and replace these components directly rather than guessing.
Combustion & venting inspection
We check for proper draft, vent obstruction, and correct venting material and slope — critical both for performance and for keeping combustion byproducts out of your home.
Burner cleaning & adjustment
Dust, lint, and sediment can clog the burner assembly over time. We clean and adjust for a clean, properly sized flame appropriate to Denver's altitude.
Local considerations in Northglenn & the Denver metro
At roughly 5,280 feet of elevation, gas appliances need altitude-derated BTU input and correctly sized venting — a unit installed to sea-level specs, or serviced without accounting for elevation, is more prone to weak or unstable flame and inefficient heating. We check altitude compensation as a standard part of every gas water heater repair.
Frequently asked questions
Why does my pilot light keep going out?
The most common cause is a worn or failing thermocouple (or flame sensor on newer units), which is a straightforward, affordable repair. Drafts near the unit and a dirty pilot assembly are other common causes we check.
Is a gas smell near my water heater dangerous?
Yes — treat any persistent gas odor as an emergency. Leave the area, avoid switches or open flame, and contact your gas utility's emergency line, then call us to inspect once it's confirmed safe.
Can low gas pressure cause water heater problems?
Yes. If other gas appliances were added to your home's line since the water heater was installed, the water heater may now be gas-starved, causing weak burner performance. We test supply pressure as part of diagnosis.
How often should a gas water heater be serviced?
An annual check of the burner, venting, thermocouple, and anode rod helps catch small issues before they become failures — we offer this as a standalone maintenance visit.
