A cold shower from a gas water heater usually means one thing: the burner is not firing, and something told it not to. Gas heaters are built around safety. The control valve will not open unless a thermocouple or flame sensor proves there is a flame, and many models lock out if the flame arrestor screen at the bottom gets clogged or the heater senses spilled exhaust. So the real question is which safety did its job, and why. Here in South Jordan, UT, the answer is most often a worn thermocouple, a dirty pilot or burner, a lint-choked air intake, a failing gas valve, or a vent that is no longer drafting properly.
South Jordan Water Heater does not guess with gas appliances. On every South Jordan call, our technicians test the thermocouple's millivolt output, inspect the pilot and burner flame, check gas pressure at the valve, and run a draft test at the draft hood to confirm exhaust is actually leaving the house. We look inside the combustion chamber for scorching, rust, and signs of flame rollout, which tell us whether the flue is blocked or the burner is misbehaving, and we check for carbon monoxide around the heater. One rule comes before all of it: if you smell gas, do not light anything or flip switches. Leave the house, call your gas utility from outside, and then call us once it is safe.
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.

How to Tell Something Is Wrong
Recognizing the warning signs early can save you money and keep a slow drip from turning into a flooded utility room. Keep an eye out for the following:
- A faint gas or rotten-egg smell near the heater (leave and call the gas utility)
- A vent pipe that has separated, rusted, or left scorch marks near the top of the heater
- Leaks at the drain valve, the fittings, or the bottom of the tank
- A flame that looks orange or floppy rather than steady and blue
- No hot water at all, with the burner never firing
- Popping, rumbling, or crackling sounds as the burner heats
- Showers that go cold sooner than they did a year ago
- A pilot that lights, then goes out when you release the knob
Don't Wait for a Total Failure
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 South Jordan Water Heater at (801) 998-0071 at the first sign of trouble.

Why Professional Gas Water Heater Services Matters
Two things make gas water heater work a poor DIY project: the parts involve fuel and combustion, and the symptoms overlap. A pilot outage might come from a worn thermocouple, a partly blocked pilot tube, lint on the flame arrestor screen, a downdraft, or an internal valve failure. Guess wrong and you have spent money without fixing anything. Guess wrong on a gas fitting or vent connection and the stakes are much higher, since a small leak or a spillage problem can put gas or carbon monoxide into the living space. Gas valve and heater replacements also typically call for a permit.
What a trained technician brings 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
Our workflow is simple and thorough, so nothing gets missed between the fuel supply and the relief line. Here's a look at each step our team takes:
Safety Check & Diagnosis
Before anything is replaced, we confirm the heater is safe to work on and test each part of the ignition, gas, and venting systems to pinpoint the failure.
Clear Answers & Upfront Price
You hear the cause in plain terms and get the price first. When a repair would only buy a few months on a failing tank, we say so and lay out replacement options.
Repair or Installation
Most failed ignition parts and gas valves get replaced on the spot. For replacements, we install a correctly sized heater with proper venting and code items.
Verified Safe Operation
With the burner running, we check every gas joint for leaks, confirm the vent drafts properly, and verify the burner flame and water temperature before we leave.
Water Heater Care Tips From Our Technicians
A few simple habits, like an annual flush and a quick look at the relief valve, can add years to a tank. Here are our recommendations:
- Never store flammable liquids near a gas water heater
- Flush the tank on a regular schedule so sediment never bakes onto the bottom
- Make sure your home has CO alarms that work, especially with gas appliances
- Make sure the vent pipe stays connected, sloped upward, and free of rust
- Check the anode rod every three to five years, since it protects the tank from corrosion
- Vacuum lint and dust from the flame arrestor screen at the base a few times a year
- Choose a setting of about 120 degrees to balance comfort, safety, and efficiency
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. Consider the following comparison:
| Consideration | DIY Attempt | Professional Service |
|---|---|---|
| Finding the Fault | Replace the thermocouple and hope | Millivolt, pressure, and draft tests find the cause |
| Gas Connections | Joints tightened without a proper leak test | Connections checked with leak solution or a detector |
| Exhaust Safety | Carbon monoxide risk unchecked | Vent secured with proper slope and clearance |
| Permits & Code | Permit and inspection often skipped | Permit handled where required |
| Sediment & Tank Care | Tank condition never evaluated | Sediment flushed, anode checked |
| Outcome | Symptom patched, cause remains | Root cause fixed and verified safe |
