Most gas water heaters in Reno, NV work the same basic way. Gas enters through a control valve that doubles as the thermostat and feeds a burner beneath the tank, and the hot exhaust travels up a flue through the middle of the tank and out through the vent. A thermocouple, or a flame sensor on newer electronic models, tells the valve a flame is present; without that signal, the valve shuts off the gas for safety. The design is dependable, but it has a few predictable weak spots. Thermocouples wear out, pilot tubes and burner ports clog, the flame arrestor screen at the base packs up with lint and dust, control valves fail, and vents lose their draft.
Diagnosing a gas water heater properly means checking combustion, not just parts. Across Reno, our technicians measure thermocouple output in millivolts, study the pilot and burner flame for color and shape, read gas pressure at the valve, and test draft at the hood so we know exhaust is leaving the house. We check the combustion chamber for soot and scorching, which point to a blocked flue or poor combustion air, and we test for carbon monoxide near the heater. Safety always comes first: a gas smell means leaving the house and calling the gas utility from outside before anything else, and Reno Water Heater can take over from there.
Once we know the cause, the repair is usually simple. A new thermocouple or flame sensor, a cleaned pilot tube and burner, a cleared flame arrestor screen, or a replacement gas control valve gets most heaters running again the same day. Vent problems, like a disconnected connector or a flue pipe without enough rise, are corrected on the spot. If sediment is rumbling in the tank, we flush it, and if the anode rod is spent, we can replace it. When replacement is the smarter move, we install new gas heaters sized to your household's first-hour demand, with proper atmospheric, power vent, or direct vent venting, a drip leg on the gas supply, and the expansion tank, drain pan, and strapping your local code calls for.

Signs You Need Gas Water Heater Services in Reno
Recognizing the warning signs early can save you money and keep a slow drip from turning into a flooded utility room. Watch for these telltale signs that professional help is needed:
- Loud rumbling from the bottom of the tank
- Pilot outages that keep coming back after a relight
- A cold tank and a burner that will not come on
- Hot water that runs out faster than it used to
- A faint gas or rotten-egg smell near the heater (leave and call the gas utility)
- Water pooling around the base of the heater
- Exhaust odor, rust, or moisture around the draft hood and vent pipe
- A flame that looks orange or floppy rather than steady and blue
A Slow Leak Never Stays Slow
Tanks rarely fail all at once. They corrode from the inside for months, and the warning signs show up long before the floor gets wet. If you notice any of these signs, contact Reno Water Heater at (775) 314-3959 for a prompt inspection.

Why This Job Calls for a Pro
Start with the hazards. Every gas water heater involves fuel piping, an open flame, and exhaust that contains carbon monoxide. A loose flare or threaded joint can leak gas, a vent that is disconnected or poorly sloped can spill exhaust back into the room, and a gas valve installed without a leak test is a risk you cannot see. Then there is the diagnostic side: a pilot that goes out can mean a weak thermocouple, a dirty pilot orifice, a clogged flame arrestor, a draft problem, or a failing gas valve, and replacing them one by one is slow and costly.
Our technicians approach gas heaters with instruments rather than assumptions. They measure thermocouple millivolts, read gas pressure at the valve, test draft at the hood, check for CO around the appliance, and leak-test every joint they touch. That process fixes the actual fault the first time and leaves your home safer than before. We also give you an honest assessment of the heater itself. A tank past about ten or twelve years with a failing valve or a leak is usually a replacement, and we will say so before you spend money on a repair.
What to Expect From Our Team
Every visit follows a step-by-step method built around testing first and replacing parts only when the readings call for it. Here's exactly how a typical visit unfolds:
Combustion & Component Testing
Leak and CO checks come first, then we test the thermocouple or flame sensor, gas valve, burner, and draft so we know exactly what stopped the heater.
Repair or Replace, Explained
No surprises. We explain the fault and the fix, quote it up front, and give you an honest repair-versus-replace answer on older heaters.
Same-Visit Repair
Common parts ride on our trucks, so most repairs are done in one visit. When a new heater is the answer, we handle the gas connection, venting, and required safety items.
Draft & Leak Test
A gas appliance is not finished until it is proven safe. We leak-test the connections, verify draft and flame, check for carbon monoxide, and set the temperature at a safe level.

Call (775) 314-3959 NowHow to Prevent Water Heater Problems
A few preventive steps can help you avoid a cold shower or a wet floor down the road. Here are our recommendations:
- Check the anode rod every three to five years, since it protects the tank from corrosion
- Set the gas valve near 120 degrees, because hotter water costs more and can scald
- Make sure the vent pipe stays connected, sloped upward, and free of rust
- Vacuum lint and dust from the flame arrestor screen at the base a few times a year
- Give the heater breathing room and keep flammables well away from it
- Flush a few gallons from the drain valve periodically to control sediment
- Keep working CO alarms near bedrooms and on each floor
Should You DIY or Call a Pro?
The line between a safe DIY check and a risky repair is usually the moment you need to open a gas fitting, a vent connection, or an electrical cover. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Finding the Fault | Swap parts until the pilot stays lit | Millivolt, pressure, and draft tests find the cause |
| Gas Connections | No leak detection after the work | Connections checked with leak solution or a detector |
| Venting & CO | Vent slope and connections overlooked | Draft tested and CO measured |
| Permits & Code | Straps, pan, and expansion tank missed | Installation meets local requirements |
| Tank Condition | Tank condition never evaluated | Honest read on the tank's remaining life |
| Result | Temporary fix at best | Real fault repaired and tested |
