A gas water heater is a refreshingly simple machine, which is part of why it lasts. A burner under the tank heats the water, exhaust rises through a flue that runs up the center of the tank, and a gas control valve on the front acts as both thermostat and safety shutoff. That valve only lets gas reach the burner while it senses a flame, through a thermocouple on standing-pilot models or a flame sensor on electronic ignition models. When something goes wrong, it is usually at one of those points. In Warwick, RI, we regularly find thermocouples that no longer hold the valve open, pilots starved by a lint-clogged flame arrestor screen, gas valves that have failed internally, and flue or vent problems that let exhaust spill back into the room.
Warwick Water Heater does not guess with gas appliances. On every Warwick 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.
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.

Warning Signs to Watch For
Most tanks announce trouble weeks or months ahead with rumbling noises, rusty water, or hot showers that keep getting shorter. These are the red flags our technicians see most often before a breakdown:
- Pilot outages that keep coming back after a relight
- Popping, rumbling, or crackling sounds as the burner heats
- Exhaust odor, rust, or moisture around the draft hood and vent pipe
- A silent heater with no flame and no hot water
- Soot or scorch marks around the burner access door
- A faint gas or rotten-egg smell near the heater (leave and call the gas utility)
- Showers that go cold sooner than they did a year ago
- Rust-colored hot water or rust streaks on the tank
A Slow Leak Never Stays Slow
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. Don't wait. Get Warwick Water Heater on the phone at (401) 210-2665 and we'll get a technician scheduled.

The Benefits of Professional Gas Water Heater Services
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. A wrong guess there just wastes money. 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.
Step by Step: How a Visit Works
Our workflow is simple and thorough, so nothing gets missed between the fuel supply and the relief line. Here's the short version:
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.
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
Thermocouples, flame sensors, pilot assemblies, and gas valves are usually replaced on the spot. For replacements, we install a correctly sized heater with proper venting and code 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.

Routine maintenance is almost always cheaper and easier than an early replacement. Put these technician-approved steps to work at home:
- Keep the air intake at the bottom of the heater free of lint and dust
- Keep the area around the heater clear, especially of gasoline, paint, and solvents
- Make sure the vent pipe stays connected, sloped upward, and free of rust
- Set the gas valve near 120 degrees, because hotter water costs more and can scald
- Keep working CO alarms near bedrooms and on each floor
- 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
Doing It Yourself vs. Hiring a Technician
Online videos may help in a pinch, yet lasting repairs and code-compliant installs depend on correct venting, proper relief valve discharge piping, and a trained technician. Here's a comparison:
| Consideration | DIY Attempt | Professional Service |
|---|---|---|
| Finding the Fault | Replace the thermocouple and hope | Millivolt, pressure, and draft tests find the cause |
| Gas Leaks | No leak detection after the work | Every joint leak-tested before we leave |
| Venting & CO | Draft and spillage go untested | Draft tested and CO measured |
| Permits & Code | Local code items easy to miss | Code items installed as required |
| Sediment & Tank Care | Sediment left to bake on the bottom | Honest read on the tank's remaining life |
| Outcome | Temporary fix at best | Real fault repaired and tested |
