MaintenanceUpdated July 4, 2026
When your hot water disappears, one of the most common reasons is a pilot light that's gone out. In Melrose Park, with so many homes built 50 years ago or more, older water heaters are still common and pilot light issues come up all the time. Getting your pilot relit, and making sure it stays on, isn't just about comfort. Proper function is critical for safety and protecting your home's plumbing system.
Why Pilot Lights Go Out in Local Homes
Older water heaters around the western suburbs of Chicago often run on natural gas, using a standing pilot light for ignition. These systems are reliable, but several factors can cause the flame to go out. Drafts in basements, sediment buildup at the burner, a failing thermocouple, or just age and wear can all be part of the problem. Many Melrose Park homes have clay and loam soils, which can mean a damp basement and frequent trips to the water heater for inspection or maintenance.
Safe Steps to Relight Your Water Heater Pilot
If you're comfortable working around gas appliances and your model's instructions are handy, relighting a pilot is usually straightforward. Here's what our crew recommends if you decide to try it yourself:
- Turn the gas control knob to "off" and wait several minutes to clear any gas.
- Locate the access panel and the pilot assembly (check your heater's label for diagrams).
- Turn the knob to "pilot," press it in, and use a long lighter (or the built-in igniter) to relight the pilot flame while holding the knob down.
- Continue to hold the knob for 30-60 seconds after the flame lights, then release gently.
- If the flame stays on, turn the knob back to "on." If not, repeat once. Still not working? Time to call in a pro.
Always read your manufacturer's instructions, some models have extra safety features. If you smell gas or suspect a leak at any point, leave the area and contact your utility provider and a licensed plumber immediately. Our team does not recommend relighting attempts if you are unsure about any step.
Common Water Heater Pilot Problems We Find
Some pilot issues are quick fixes. Others signal that a component is worn out or failing. Here's what we commonly see in Melrose Park homes:
- Thermocouple failure: If the thermocouple malfunctions, it won't sense the pilot flame and will shut off gas to the burner.
- Clogged pilot orifice: Sediment from moderately hard municipal water can build up and block the tiny gas jet.
- Drafts: Basements near vents or windows can blow out a small pilot.
- Faulty gas control valve: Sometimes, the control valve itself fails and won't hold the pilot.
Older homes, especially those with mid-century ranch-style or early 20th-century bungalows, often have water heaters with these parts nearing the end of their service life. Replacing a thermocouple or cleaning the burner assembly are bread-and-butter repairs for our crew.
Why Regular Maintenance Matters
With Lake Michigan's moderately hard water feeding local supply lines, sediment can settle in heater tanks and around the burner. This can block pilot orifices and shorten the lifespan of your anode rod. Regular draining and inspection help prevent these problems. If you suspect sediment buildup or want peace of mind about your water heater's performance, consider scheduling water heater services with a licensed local plumber who knows the quirks of Cook County homes.
We often recommend a quick visual check every few months. If you spot rust, corrosion, or water pooling near the tank, it could point to bigger issues with the system. For older pipes or if you're dealing with repeated leaks, our pipe repair and repiping team can help assess what's going on behind your walls.
When to Bring in a Licensed Professional
Most pilot relights are straightforward, but certain warning signs mean you need help:
- You smell gas before or after your attempt
- The pilot won't stay lit after repeated tries
- There's visible rust, corrosion, or water leaking from the heater or gas connection
- You're unsure which control or part to use
In these cases, safety comes first. Gas leaks, faulty safety valves, or deeper issues in aging plumbing systems need professional diagnosis. Our licensed plumbers are equipped to handle complete inspections, part replacement, and full heater rebuilds. If you have broader water issues, including leak detection and repair or water line services, scheduling service before a small problem grows can save thousands on repairs down the line.
Preventing Future Pilot Light Outages
Preventive maintenance is the best way to minimize outage headaches. Flushing your tank annually helps keep burners clean. Replacing the anode rod when needed protects against corrosion. Make sure your heater's intake isn't blocked and that nothing near the base can create a draft. If your heater is more than 10-15 years old or you're considering an upgrade, our water heater services include installation and recommendations for high-efficiency units that fit older and newer Melrose Park homes alike.
