If the smell isn’t from the stream of water, but from the sink itself, your drain might be the culprit. Food scraps, grease, and soap buildup create a bacterial slime in the P-trap that smells like a zoo cage. Run hot water and baking soda down the drain, then vinegar—it’ll fizz and clean it out.
Why Does My Tap Water Smell Musty? (Causes & Easy Fixes)
If that doesn’t work, you might have a dry P-trap (common in guest bathrooms). Pour water down the drain every week to keep the trap sealed. Yes, you now have a plumbing chore. Welcome to adulthood.
Gasoline, chemicals, or sweet smells
This one is not a joke. If your water smells like gasoline, paint thinner, or maple syrup, stop drinking it immediately. Gasoline indicates a leak from a nearby tank or runoff; sweet smells can mean methamphetamine contamination from illegal labs (yes, really). Call your water utility and a plumber—this is a health emergency.
Most of the time, though, it’s just a weird case of biology or chemistry in your pipes. Happens to the best of us. Last week I caught myself sniffing the glass like a wine critic before a sip.
Bottom line: trust your nose. If the smell is temporary and faint, flush the lines or change the filter. If it’s strong, persistent, or metallic, get it tested. Your home isn’t haunted—it’s just a little ripe.
