Water Heater Is Leaking: What to Do Now

Your water heater is leaking and needs quick attention to prevent water damage and costly repairs. Whether water pools around the base, drips from the bottom, or seeps from connections, understanding the leak source helps you respond appropriately. We'll also cover what to do if this unit develops a leak from the bottom, the most common scenario, and provide actionable steps to protect your home while you arrange water heater leak repair.

What to Do If Water Heater Is Leaking From Bottom

Turn off the water supply and power immediately. Identify whether water pools at the tank base or drips from a valve. Then call a professional to assess your specific situation. A failing tank typically requires replacement, while a faulty drain valve or loose fitting may be salvageable through water heater repair.

Shut Off Water Supply Immediately

When your water heater is leaking from the bottom, shut off the water supply and power immediately to prevent further damage and safety hazards. A bottom leak typically indicates a failing tank with corrosion or a broken drain valve, which usually requires water heater repair or replacement rather than a simple fix. Act fast to minimize water damage to your flooring and foundation.

Inspect Tank and Drain Valve

When my water heater is leaking from the bottom, the tank itself is likely compromised and replacement is usually necessary rather than repair. Stop using hot water immediately and turn off the power supply, then shut off the water inlet valve to prevent further leakage and water damage to your home. Contact a water heater repair professional to assess whether salvage is possible or if what to do if water heater is leaking from bottom requires a full unit replacement.

A water heater leaking from the bottom demands quick diagnosis and action to prevent extensive water damage and determine if repair or replacement is necessary. Below are the key diagnostic steps and immediate response protocols to assess your situation and protect your home.

Turn off your water heater immediately if you notice active leaking. This prevents further water damage and gives you time to assess the situation without pressure. Most leaks at the bottom signal serious internal corrosion that requires professional evaluation.
Identify the leak source by checking if water originates from the tank bottom, drain valve, or temperature-pressure relief valve. A leak from the bottom typically indicates tank failure, while valve leaks are often repairable. Document the leak location and flow rate for your technician.
Place towels or a bucket under the leak to contain water and protect your flooring. This buys you time before scheduling water heater repair and prevents costly water damage to your home's foundation or surrounding structures.
Yes, you can take a shower if your water heater is leaking from the valve or drain, but avoid showering if the tank itself is compromised. A leaking tank means your water heater won't hold temperature effectively, and the leak will worsen with use.
Shut off the water supply to your heater if the leak is severe or actively spreading. Locate your main water shut-off valve and close it partially to slow the leak while you arrange professional service.
Don't attempt DIY repairs on leaking tanks. Internal corrosion that causes bottom leaks requires replacement, not patching. Attempting repairs delays proper service and risks additional water damage or personal injury.
Contact a professional immediately if you notice rust-colored water or a leak from the tank base. These signs indicate your water heater is leaking due to internal deterioration and needs prompt replacement to prevent catastrophic failure.
