Water Heater Leak vs. Condensation: How to Tell the Difference
That puddle under your heater might be harmless winter condensation — or a real leak. Here's how to tell before you pay for a repair you don't need.
Read More →From mysterious puddles to rusty water, here are the seven warning signs your water heater is leaking — and which ones mean calling for help today.
The most obvious sign — and the one most often dismissed as 'just condensation.' If water reappears after you mop it up, it's a leak until proven otherwise. Check whether it returns within a few hours; condensation is cyclical, leaks are relentless.
That pipe running down the side of your tank should be bone dry. If it's dripping, your temperature-and-pressure relief valve is opening — which means pressure or temperature inside the tank is too high. This one deserves a prompt service call, not a bucket.
This is the sign people ignore because the water 'still works.' Rust in hot water (but not cold) means the inside of your tank — or the anode rod protecting it — is corroding. A leaking tank often follows within months. Don't wait for the flood to confirm it.
Slow leaks announce themselves by smell before sight, especially in finished basements where water wicks into drywall and framing. If the utility area smells musty and it didn't used to, investigate.
Sediment-baked tanks and failing components make the burner or elements run longer. Higher gas or electric bills with no other explanation can be an early leak warning — the system compensating for lost efficiency.

Call (833) 713-2101Green crust on copper fittings, rust streaks below pipe joints, or a corroded drain valve are all leak precursors. Corrosion doesn't reverse itself; it only progresses.
A cracked dip tube or heavy sediment displaces hot water capacity, but so does a slow internal leak changing the tank's thermal behavior. If recovery has noticeably worsened — especially heading into winter — get it checked.
Don't panic, but don't procrastinate either. Shut off the water inlet if you see active pooling, note what you observe (photos help), and call a professional for diagnosis. Most leaks we see in Medford started as one of these seven signs weeks earlier — caught early, the fix is usually a valve or fitting, not a new heater.
No. Mineral deposits can temporarily slow a weep, but pressure and thermal cycling always reopen it — usually at the worst moment, like a January cold snap.
More urgent than it looks. Small drips become bursts, and the water damage costs far more than the repair. A same-week service call is the smart move.
Only if it's actively flooding and you've shut off power/gas first. For slow leaks, leave it — a drained tank with power on will destroy electric elements in seconds.
