Pilot Won't Stay Lit

How a Gas Water Heater Works and Where It Fails
A gas tank heater relies on a few parts working together. The gas control valve senses water temperature and opens the gas supply. A pilot or electronic igniter lights the burner under the tank. A thermocouple, thermopile or flame sensor proves the flame is there, and the flue carries exhaust up through the tank and out the chimney or vent.
When any one of these parts weakens, the burner stops firing and your hot water fades. Gas hot water heater repair is about finding which link broke, fixing it safely and confirming the exhaust leaves your home the way it should.

Common fixes
Gas Water Heater Problems You Can Get Fixed
These are the faults behind most calls to repair gas water heater systems in Everett basements.
Weak, Yellow or Lifting Flame
A healthy flame is mostly blue. Yellow or lazy flames point to a dirty burner, restricted air supply or wrong gas pressure, which can create carbon monoxide.
Failed Gas Control Valve
If the pilot lights but the burner never fires, or water temperature swings wildly, the gas valve and its built-in thermostat may need replacing.
Clogged Flame Arrestor
Newer sealed-combustion tanks pull air through a screen at the base. Lint and dust from nearby laundry clog it and choke the burner until it shuts down.
Power Vent Motor Faults
Power-vented models use a blower to push exhaust out a sidewall. A noisy, tripping or dead blower stops the whole heater.
Short Hot Water Supply
Sediment on the tank floor or a broken dip tube means hot water runs out sooner than it should, even though the burner works.
Smell Gas Near Your Water Heater? Act Now
- Do not light matches or flip any light switch.
- Leave the building with everyone, including pets.
- Call 911 or your gas company from outside.
- Once it is safe, call (617) 440-9468 to repair the heater.
Safety first
Carbon Monoxide and Gas Safety
A gas water heater that is not venting properly can spill carbon monoxide into your basement. Watch for soot around the draft hood, a rusty top, condensation dripping from the vent pipe or a CO alarm going off.
Massachusetts law, known as Nicole's Law, requires working carbon monoxide alarms in homes with fossil-fuel burning equipment. Every gas water heater service visit includes a draft and spillage check so you know exhaust is leaving the house.
An Everett-specific issue
Chimney Venting in Everett's Older Homes
The Orphaned Water Heater Problem
In many older two-families and triple-deckers, the gas water heater shares a masonry chimney with the boiler. When the boiler gets replaced with a high-efficiency unit that vents out the side wall, the water heater is left alone in a chimney that is far too big for it. Weak draft, condensation and spillage follow.
The Fix
A properly sized chimney liner or a new vent connector restores draft. Your technician checks the connector slope, joints and chimney condition, then performs a spillage test with the heater running so you know the venting works.
Done by the book
Licensed Gas Water Heater Plumber, Permitted Work
In Massachusetts, work on gas piping, gas valves and gas appliance connections falls under the state plumbing and gas code and must be done by a licensed gas fitter or plumber. Larger jobs need a permit through the plumbing and gas division of Everett's Inspectional Services at City Hall.
Every gas water heater plumber you get through this service is licensed for that work. That protects your safety, your insurance coverage and your home's resale value.

FAQ
Gas Water Heater Repair FAQs
Why won't the pilot on my gas water heater stay lit?
A worn or dirty thermocouple is the most common reason. Other causes include a weak pilot flame, a clogged flame arrestor, a draft problem blowing the pilot out or a failing gas control valve.
Can I replace the thermocouple on my water heater myself?
Massachusetts requires a licensed gas fitter for work on gas appliances and controls. A professional also checks why the thermocouple failed, since a draft or venting problem can cause repeat failures.
What does gas water heater service include?
A typical gas water heater service visit covers pilot and burner inspection, cleaning the burner and flame arrestor, testing the gas valve, checking the relief valve and confirming the venting drafts correctly.
Is a yellow flame on my water heater dangerous?
A yellow or lazy flame means incomplete combustion, which can produce carbon monoxide. Turn the heater off and call for service, and make sure your CO alarms are working.
How long does gas hot water heater repair take?
Most repairs such as a thermocouple, igniter or burner cleaning take one to two hours. A gas control valve replacement takes longer because the tank must be partly drained.
