Most gas water heaters in Henderson, 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 closes 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 Henderson, 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. Keep one rule in mind: a gas smell means leaving the house and calling the gas utility from outside before anything else, and Henderson Water Heater can take over from there.
Some gas heaters need a quick part swap, and some need an honest conversation. We handle both. Thermocouples, flame sensors, pilot assemblies, hot surface igniters, gas valves, and burner cleaning are routine repairs, and we correct venting faults and flush sediment during the same visit when needed. If the tank is leaking, rusting through, or past about ten to twelve years with a major failure, we will explain why replacement makes more sense. Our installations cover like-for-like swaps and upgrades to power vent or high-efficiency models, with correct gas line sizing, sediment traps, expansion tanks, drain pans, and seismic strapping wherever required.

Symptoms That Mean It's Time to Call
Water heaters usually give plenty of warning before they fail, as long as you know what to look and listen for. Keep an eye out for the following:
- Popping, rumbling, or crackling sounds as the burner heats
- Signs of backdrafting, such as soot, condensation, or an exhaust smell at the vent
- Showers that go cold sooner than they did a year ago
- A rotten-egg odor near the water heater, in which case get out and call the gas company first
- A pilot light that will not stay lit
- A flame that looks orange or floppy rather than steady and blue
- No hot water at all, with the burner never firing
- Water pooling around the base of the heater
Early Action Saves Money
A little rust-colored water or a relief valve that drips now and then can be the first hint of a tank that is close to the end. Call Henderson Water Heater at (725) 200-0504 at the first sign of trouble.

Why This Job Calls for a Pro
Gas water heaters are among the riskiest appliances to work on without training, because the biggest hazards are invisible. A gas connection that is not quite tight can leak slowly for days. A vent connector that has lost its slope, or a flue partly blocked by debris, can let carbon monoxide spill into the house every time the burner fires, with no smell to warn you. Gas valve and heater replacements also typically require a permit and an inspection. Relighting a pilot by following the label is something most homeowners can do; almost everything past that deserves a technician.
The value of calling a pro is certainty. We test instead of guessing, from thermocouple millivolt readings and burner flame checks to gas pressure at the valve and a draft test at the hood. We leak-test every connection, confirm the vent is carrying exhaust out of the house, and check CO before we leave. And because some gas heaters are not worth another repair, we give you a straight answer on repair versus replacement first, then handle either one with correct venting, gas piping, and the code items your installation requires.
From Your Call to Hot Water
We follow the same careful process on every water heater, whether it's a quick thermostat swap or a full tankless conversion. Here's the short version:
Safety Check & Diagnosis
Safety comes first, with a gas leak check and a CO reading. Then we measure thermocouple output, inspect the pilot and burner, read gas pressure, and test the vent's draft.
Clear Answers & Upfront Price
We show you what failed, explain why, and quote a firm price up front. If the tank is leaking or near the end of its life, we tell you so.
Expert Repair or Replacement
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 to about 120 degrees.

A little routine care goes a long way toward keeping a water heater running well past its expected lifespan. Start with these practical measures our team relies on:
- Never store flammable liquids near a gas water heater
- Watch for a loose, rusted, or sagging vent pipe above the heater
- Replace a spent anode rod before the tank itself starts to rust
- Drain sediment from the bottom of the tank once or twice a year
- Keep working CO alarms near bedrooms and on each floor
- Keep the air intake at the bottom of the heater free of lint and dust
- Set the gas valve near 120 degrees, because hotter water costs more and can scald
Should You DIY or Call a Pro?
A few tasks, like checking the temperature setting or lifting the relief valve lever to test it, are fine for homeowners, but most water heater work involves gas lines, venting, 240-volt circuits, or a tank full of scalding water, and that belongs with a professional. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Diagnosis | Replace the thermocouple and hope | Instruments pinpoint the actual failure |
| Gas Leaks | Joints tightened without a proper leak test | Gas piping verified tight and sound |
| Exhaust Safety | Vent slope and connections overlooked | Spillage and CO checked at the appliance |
| Code Compliance | Local code items easy to miss | Code items installed as required |
| Tank Condition | Sediment left to bake on the bottom | Honest read on the tank's remaining life |
| Result | Temporary fix at best | Real fault repaired and tested |
