Common Reasons a Water Heater Is Leaking From Bottom

Immediate Safety Steps: What to Do in the First 5 Minutes

Finding water pooling under your heater is stressful — but those first five minutes matter most. Here’s exactly what to do.
Cut the Power First
Electric Heater?
Flip the breaker switch in your electrical panel immediately. Never touch a water heater with standing water around it — water and electricity are a deadly combination.
Gas Heater?
Turn the thermostat dial to the “Pilot” setting. This shuts down heating without fully cutting the gas line.
Shut Off the Cold Water Supply
Find the cold water inlet valve sitting on top of your unit. Turn it clockwise until it stops. This prevents more water from flooding in and making things worse.
Contain the Damage
Grab towels, buckets, or a wet vacuum to protect your floors. Water damage spreads faster than most people expect.
Don’t Touch the Hot Water Tap

The other possibility is your temperature and pressure relief valve, also called the T&P valve. This little valve is actually a safety feature that releases water when pressure inside the tank climbs too high. So if that’s your culprit, your heater is basically just doing its job.
Water Coming From the Bottom?
Now this is where you need to pay close attention. A bottom leak is almost always a sign that something more serious is going on inside your tank. Over the years, minerals from your water supply sink to the bottom and just sit there. Slowly, over time, that sediment starts corroding the inner lining of your tank — and eventually you end up with tiny cracks or pinhole leaks that let water seep through.
How to Tell If the Tank Itself Has Failed

Signs that the tank has failed encompass rust-coloured water, popping or rumbling noises, decreased warm water capacity, and seen corrosion across the base of the unit.
