Leaking water heater
Not every puddle means a dead tank. Where the water starts tells you — and your contractor — most of what matters.

Turn off the heater's breaker only from a dry floor. If you smell gas, leave the home and call your gas utility from outside.
Limit the water
Stop using hot water. If you can do so from a dry spot, turn off the heater's energy supply first, following the instructions on its label — the dedicated breaker for an electric unit, or the setting the label describes for a gas unit — or wait for a professional if you're unsure. Never touch a wet or damaged panel or stand in water to reach a switch. Then, if the valve is dry and reachable, close the cold-water shutoff on the inlet pipe at the top; that stops the tank from refilling and usually slows a leak. Place towels or a shallow pan to protect the floor, and move stored boxes away. Don't try to drain a hot tank yourself — the water can scald, and an old drain valve may not reseal.
Find where it starts
Dry the area with a towel, wait a few minutes, and look carefully. A flashlight and a phone photo help.
| Where you see water | What it can indicate | Usually |
|---|---|---|
| Top of tank, at pipe connections | Loose or corroded fitting, worn dielectric union, supply line | Often repairable |
| Relief-valve discharge pipe on the side | The temperature & pressure relief valve opening — from excess pressure, high temperature, or a worn valve | Needs a professional check; never cap or plug this pipe |
| Drain valve near the bottom | Valve not fully closed or a worn valve | Often repairable |
| Nearby pipes or a softener / filter | Leak isn't the heater at all | Trace the source first |
| Light moisture on a cold day, gas unit | Condensation as the burner heats cold incoming water | May be normal if it stops once warm |
| Bottom seam, rust streaks, under the jacket | Internal tank corrosion | Tank failure — plan replacement |
Why a tank leak is different
The inner steel tank on a conventional water heater can't be patched reliably. Once it leaks from the body, the practical answer is replacement. That's why identifying the source matters: you don't want to replace a heater because of a repairable fitting, and you don't want to pay to repair a valve on a tank that's already failing. Our repair-or-replace guide walks through the trade-offs.
What to tell the contractor
- Photos of the leak location and the rating label (brand, model, serial, gas or electric, gallons).
- Whether the leak is a drip, steady flow, or only after the heater runs.
- Whether you closed the supply valve or turned off power/gas.
- Access details: basement stairs, crawlspace, closet, finished room below.
- If you rent, your landlord's name and whether they approve repairs.
Common questions
Is a dripping relief valve dangerous?
The valve is a safety device doing its job or wearing out. Either way it needs a qualified look. Never cap the discharge pipe.
Will insurance cover water damage?
That depends on your policy. Photograph damage before cleanup and contact your insurer; this site can't advise on coverage.
