You just found water where it shouldn't be. Take a breath — this is manageable if you act in the right order. These are the exact steps our technicians talk Westfield homeowners through on emergency calls, refined over thousands of leaks.
Step 1: Stay safe first
If water has reached electrical outlets, the furnace, or the breaker panel — or if you smell gas — don't wade in. For gas odor, leave the area and call from outside. Electricity and standing water are a deadly combination; no water heater is worth that risk.
Step 2: Shut off the water supply
Find the cold-water shutoff valve on the pipe entering the top of the heater and turn it clockwise until it stops. This halts new water feeding the leak. If that valve is seized (common on older units), shut off the home's main water valve instead.
Step 3: Kill the power or gas
Electric: flip the water heater's breaker to OFF. Gas: turn the control knob to PILOT or OFF. A heating tank with dropping water levels can overheat dangerously — never leave a leaking heater powered.
Step 4: Control the damage
Mop or towel up standing water, move boxes, rugs, and valuables away, and crack a garage door so water drains out. If the leak is upstairs or near finished space, place towels as a barrier and move electronics first.
Step 5: Call a professional
Call (833) 713-2101 — describe what you see and what you've shut off. We'll dispatch immediately for active leaks. Don't try to drain the tank yourself in an emergency; scalding water and mis-set valves cause most DIY injuries we hear about.
What NOT to do
- Don't cap or plug a dripping T&P discharge pipe — it's a critical safety device.
- Don't touch a heater sitting in water while it's still powered.
- Don't ignore a “small” leak until morning if water is spreading.
- Don't restart the heater until a professional has inspected it.
