A few drops today could mean gallons of trouble tomorrow. A leaking water heater might seem like a small nuisance, but it can quickly lead to water damage, higher utility bills, or even an unexpected emergency. If you’ve spotted water pooling around your unit and are wondering what to do if hot water heater is leaking, you’re not alone—many homeowners face this issue at some point.
At Mad Pipers Plumbing, we understand how stressful a heater leak can be. That’s why we’ve put together this detailed, easy-to-follow guide to help you take immediate action, protect your home, and know when it’s time to call in professional plumbing services.
Stay Calm and Assess the Leak
Before grabbing a wrench or calling for emergency service, take a moment to assess the situation safely. Look around the unit and determine where the leaking water is coming from. It could be dripping from the relief valve, drain valve, or the tank itself.
If you see water spraying or pooling quickly, it’s likely a major heater leak, and you should act fast to prevent water damage. If the leak is minor or just dampness, you may have more time to troubleshoot before calling Mad Pipers Plumbing for help.
Pro tip: Always keep a towel or bucket nearby to contain leaking water until you identify the source.
Turn Off the Power Supply
Safety first—never work around a water heater that’s still powered on. Since hot water heaters use either electricity or gas, shutting off the power prevents further damage and reduces the risk of electrical hazards.
- For electric water heaters: Find your circuit breaker and flip the switch labeled “Water Heater” to the OFF position.
- For gas heaters: Locate the gas shut-off valve and turn it to the OFF setting.
This step not only keeps you safe but also stops the unit from continuously trying to heat while leaking water accumulates. If you’re uncertain about handling power or gas connections, call Mad Pipers Plumbing immediately. Our technicians can safely manage the process for you.
Shut Off the Water Supply
Once the power is off, it’s time to prevent additional water from entering the tank. Look for the water shut-off valve located at the top of the unit—typically a lever or wheel-style handle. Turn it clockwise to stop the flow.
If the valve feels stuck or corroded, don’t force it. Mad Pipers Plumbing can assist in shutting down the system properly and inspecting for any faulty valves or pressure issues that could be contributing to the leak.
Stopping the water flow early can prevent costly water damage to your floors, walls, or foundation.
Drain the Tank Carefully
Now that no new water is entering, you’ll need to remove the hot water still inside. Connect a garden hose to the drain valve at the base of your heater, directing the other end to a nearby floor drain or outside. Open the valve slowly and allow the tank to empty.
Draining your water heater helps prevent further leaking and allows for inspection. Be cautious—the water will still be hot, so handle the hose carefully to avoid burns.
If you’re not comfortable performing this maintenance step, Mad Pipers Plumbing provides safe and efficient drain valve servicing as part of our plumbing and heater repair offerings.
Inspect the Source of the Leak
With the tank drained, take a closer look at where the leaking water originated:
- Top of the unit: May indicate loose or corroded fittings on inlet/outlet pipes.
- Side of the tank: Could be a faulty relief valve releasing excess pressure.
- Bottom of the tank: Often signals internal corrosion or cracks—requiring professional heater repair or replacement.
If you can’t find the exact cause, don’t worry. The experts at Mad Pipers Plumbing use advanced diagnostic tools to identify hidden water leaks and recommend the right fix for your home’s plumbing systems.
Check the Pressure Relief Valve
One of the most common culprits in a heater leak is the pressure relief valve—a small but critical component that keeps your heater safe. If pressure builds up too high, this valve releases water to prevent the tank from bursting.
Inspect the relief valve for signs of corrosion, drips, or constant leaking. A small amount of water discharge can be normal, but if it’s continuous, the valve may be faulty or your heating system could be overpressurized.
Mad Pipers Plumbing can replace the relief valve, balance your heater’s pressure, and ensure your plumbing system runs safely and efficiently.
Examine for Corrosion or Rust
Rust or corrosion on the water heater exterior or around fittings often points to a long-term leak problem. Over time, sediment buildup and moisture can eat away at the metal, leading to structural failure.
If you notice rust-colored water, discolored puddles, or corrosion around connections, it’s time to call Mad Pipers Plumbing for heater repair or replacement. Ignoring corrosion could result in a tank rupture—a costly and dangerous issue.
Regular maintenance from Mad Pipers Plumbing helps prevent corrosion through flushing, inspections, and system tune-ups.
Evaluate If You Need Professional Repair or Replacement
Once you’ve followed these steps, you’ll have a better idea of whether you can handle the leak with a quick fix or need professional help. Small issues like a loose valve might be simple, but larger heater leaks or internal tank damage usually require expert attention.
