Water Heater Pilot Light Won't Stay Lit: What It Usually Means

Water Heater Pilot Light Won't Stay Lit: What It Usually Means

A pilot light that will not stay lit is most often a worn thermocouple that fails to signal the gas valve to stay open, though a dirty pilot orifice, a draft in the burner compartment, or a failing gas control valve can also cause it - if you smell gas at any point while checking this, stop immediately and follow the gas safety steps rather than continuing to relight it yourself.

Decision guide

How to decide what happens next

Start by identifying whether the issue is isolated to one fixture or affects several drains. If the problem is spreading, includes dirty water, or risks property damage, treat it as urgent and request provider guidance.

Common questions
What is the quick decision?

A pilot light that will not stay lit is most often a worn thermocouple that fails to signal the gas valve to stay open, though a dirty pilot orifice, a draft in the burner compartment, or a failing gas control valve can also cause it - if you smell gas at any point while checking this, stop immediately and follow the gas safety steps rather than continuing to relight it yourself.

When should I call instead of waiting?

Call when water damage, wastewater, essential fixture loss, or repeated backup symptoms are present.

What should I do first during a plumbing emergency?

Stop the water source if safe, avoid using affected fixtures, protect people from contaminated water, and request help.

What should I do during an active leak?

Use the closest working shutoff valve, keep water away from electrical areas, and request leak help quickly if water keeps spreading.

When should a drain backup be treated as urgent?

Treat it as urgent when more than one fixture backs up, wastewater appears, or the problem blocks essential use.

Which sewer symptoms need fast attention?

Multiple slow drains, sewer odor, toilet gurgling, dirty tub water, or outdoor cleanout overflow should be treated as urgent warning signs.

When does fixture loss become urgent?

No usable toilet, no hot water for vulnerable occupants, or water near unsafe areas can justify urgent guidance.

Can I use chemical drain cleaner during a backup?

Avoid chemical cleaners once water has backed up. They can create splash risk and may not solve a deeper blockage.
