Why is My Hot Water Heater Leaking?

Some people think that it is normal to see water outside of the water heater. However, while some water might not be cause for concern, you should keep an eye on it to make sure that it doesn’t escalate.

A small leak may seem like no big deal, but over time, the water can cause severe damage and can even lead to a flood. A water heater leak will never go away on its own.

Common Causes of Water Heater Leaks


As water filters through your water heater sediment and minerals from the water collect and settle at the bottom of the tank. All of this buildup eventually causes corrosion on the bottom of your water heater which can form a leak over time.

While this is one of the most common causes of water heater leaks, you can prevent them by flushing your tank once every six to 12 months. This will prevent too much sediment from building up at one time.

Temperature and Pressure Relief Valve

Every water heater has a valve called the temperature and pressure relief valve. This device is mandatory and is in place to prevent too much pressure from building in the water heater. If there is too much pressure in the tank or the water exceeds the set temperature, then you might see water running down the side of the tank from the valve.

This water could be a sign of two things, either you have a broken valve, or your tank has too much pressure. If you notice water leaking from this valve it’s best to call a professional rather than trying to fix it yourself as it could lead to more significant problems.

Inlet and Outlet Connections

All valves or connections are susceptible to leaks over time either because they have worn down or they have loosened. The inlet connection is used to flow cold water into the water heater, then after the water heats, it exits as hot water through the outlet connection.

If these connections are the source of your leak, then you shouldn’t have any problems resolving the issue yourself. Check both connections to be sure of where the leak is occurring and then tighten the connection with a wrench. If you have a faulty pipe, you’ll need to replace it. You should be able to do this on your own as well, but if you have any issues, then call a professional plumber.
