Hydrogen Sulfide Is a Common Cause
The familiar rotten-egg odor can be caused by hydrogen sulfide, but the source may be the well, plumbing or water heater.
Hot vs. Cold Water Matters
Note whether the odor is present only in hot water, one faucet or every fixture. That observation helps determine the next test and treatment approach.
