If you’ve just discovered a growing puddle of water around your utility closet or basement water heater, take a deep breath! While a leaking water heater can be incredibly stressful, panicking will only cost you valuable time. It is important to stay calm and take immediate action. If you are dealing with a leaking tank, you must stop the flow of water right away. Acting fast helps prevent severe property damage, ruined flooring, and dangerous basement mold growth.
If you are wondering exactly what to do when water heater leaks happen, follow this simple three-step emergency guide. This checklist will help you safely secure your system before calling a professional plumber to your home.
3-Step Emergency Guide to Stopping a Water Heater Leak
- Turn off the water supply: Look for the cold water intake pipe entering the very top of your unit. You will find a gate valve (a wheel-like handle) or a ball valve (a straight lever). Turn the wheel clockwise, or pull the lever so it sits perfectly straight across the pipe. This will stop the incoming water from feeding the leak.
- Turn off the power or gas: You must eliminate the heat source to keep the system safe. For an electric water heater, go to your home’s main electrical panel and flip the breaker for the heater to the “off” position. For gas water heaters, locate the thermostat dial near the bottom of the tank and turn it to “Off,” or turn off the dedicated shutoff valve on the gas line.
- Diagnose the leak source: Once the system is safe, powered down, and no longer filling with water, grab a flashlight. Carefully inspect the water heater tank to see where the water is coming from. The location of the puddle will tell you a lot about the health of your system.
Hot Water Heater Leaking From Top
If you notice your hot water heater leaking from top, you might actually be in luck. Most of the time, this specific issue is easily fixable and does not require a total system replacement. Top leaks are typically caused by loose plumbing connections. Check the cold water inlet pipe and the hot water outlet pipe. If the metal fittings are wet, they might just need to be tightened by a professional.
Another common cause when your heater is leaking from the top is a problem with the temperature and pressure relief valve. Also known as the T&P valve, this is a crucial safety feature on every single water heater. If your home has high water pressure, or if the tank gets far too hot, this valve opens up on its own. It releases water to lower the pressure and stop the tank from bursting.
Sometimes, these safety valves simply get stuck open or become faulty over time. If this valve is broken and leaking, a certified plumber can easily swap it out for a new one. You will just need a standard water heater repair rather than a whole new plumbing system.
Water Leaking From Bottom of Water Heater
If you have water leaking from bottom of water heater, the situation is usually much more serious. First, check the drain valve located near the floor at the base of the tank. Sometimes, this valve simply becomes loose if it gets bumped. Its internal rubber washer can also dry out and fail, causing a steady drip. If the drain valve is the problem, a plumber can replace the valve quickly.
However, if the drain valve is completely dry, you have a much bigger problem on your hands. Water pooling from underneath the metal outer casing means the inner tank has suffered a catastrophic failure. Over time, natural minerals and hard sediment build up at the very bottom of the tank. This hot sediment eats away at the internal glass lining and rusts the steel frame from the inside out.
Once the metal tank rusts through and cracks, it cannot be patched or saved. This is why replacing the anode rod during routine annual maintenance is so incredibly vital. The anode rod is designed to attract those corrosive minerals to protect the steel tank. But once the rod is gone and the tank itself cracks, it is simply too late for a repair.
