What to Do When Your Water Heater Leaks

Water spreading from your heater? These six steps — in order — minimize damage and keep you safe until professional help arrives.

Step 1: Stay Calm and Assess

Take ten seconds to look before you act. Is water gushing or dripping? Is it near electrical panels, outlets, or the heater's own wiring? Is there any smell of gas? Your answers determine everything that follows — and if you smell gas, skip to Step 6 immediately.

Step 2: Shut Off the Water

Find the cold-water inlet valve above the heater (usually a lever or wheel on the pipe entering the top) and turn it clockwise — or perpendicular for lever handles. This stops new water from feeding the leak. If the valve is seized (common on old installs), shut off the home's main water valve instead.

Step 3: Kill the Power or Gas

For electric heaters: switch off the dedicated breaker — never trust just the thermostat. For gas: turn the control valve to PILOT or OFF. This prevents dry-firing damage and eliminates ignition and scald risks while water is where it shouldn't be.

Step 4: Contain the Water

Towels, mops, and a wet-vac are your friends. Move valuables, boxes, and electronics away from the water path. If water is near electrical outlets or your breaker panel, don't wade in — wait for help.

Step 5: Document and Call

Snap photos of the leak source and any damage for your records (and potential insurance). Then call (833) 713-2101 — we answer 24/7 and will talk you through anything you're unsure about while dispatching a technician.

Step 6: The Gas Exception

If you smell gas — rotten-egg odor — do NOT touch the heater, switches, or your phone inside. Leave the house and call your gas utility or 911 from outside. Only after officials clear the home should you call us for the repair.

What NOT To Do

Don't cap or plug a dripping T&P valve. Don't try to solder or patch a pressurized tank. Don't restore power to a drained electric heater. And don't assume a leak that 'stopped' is fixed — mineral-clogged weeps always reopen.

Frequently Asked Questions

Should I drain the tank completely?

If it's a major leak and the water is off, partly draining reduces the mess — but attach a hose to the drain valve and route it to a floor drain. Never drain an electric heater without killing the breaker first.

Can I still use hot water while waiting?

If the leak is minor and contained, limited use is usually fine — but watch it closely. For active leaks, shut it down and wait for the technician.

Will my homeowner's insurance cover the damage?

Sudden water heater failures are typically covered for the resulting damage (not the heater itself), but policies vary. Document everything with photos and call your insurer promptly.
