Common Leak Cause 1: Loose Hot/Cold Water Connection
One common reason for water heater leaks is a loosened connection on the hot or cold water inlet and outlet pipes. With regular use and temperature changes, these connections can loosen up, causing water to seep out. Sometimes, you’ll notice small puddles around the heater or a slow drip from the pipes.
To troubleshoot, take a look at the heater’s top connections. If you spot any water or moisture, a loose connection might be the culprit. A quick tightening with a wrench could do the trick but be careful not to overtighten and cause more damage.
Common Leak Cause 2: Faulty Pressure Relief Valve
A malfunctioning pressure relief valve is another common reason for water heater leaks. This valve is meant to release extra pressure inside the tank. If it’s not working properly, water might leak out, signaling high tank pressure and posing the risk of the tank bursting.
To see if the valve is causing the issue, gently lift its lever. If it’s working, water will flow out. But if it continues to leak after you let go, you might need to replace it.
Common Leak Cause 3: Defective Temperature & Pressure Valve
Similarly, the temperature and pressure (T&P) relief valve can sometimes cause leaks. If you notice the T&P valve leaking, it could mean the water temperature is too high or the tank pressure is too much. Both of these issues need attention right away.
To troubleshoot this issue, take a look around the valve for any water. If you notice it’s wet, you might need to replace it.
Common Leak Cause 4: Leaking Inlet Valve
Lastly, a damaged or improperly sealed inlet valve—responsible for controlling cold water flow into the water heater—could cause a leak. If the inlet valve isn’t working right, you’ll often find water pooling around the base of the heater.
To fix this, check the inlet valve for any signs of damage or wear. You might need to tighten or replace the valve.
