Why is My Water Heater Leaking?

Have you noticed water dripping from your water heater? Or maybe there is a little puddle accumulating near the bottom. Either way, water leakage is no joking matter, as it can damage floors and walls and even ruin furniture. 

If you suspect that your water heater may be leaking, read on to learn about the causes of water heater leaks and when you should seek professional help.

Your Water Heater is Old

The number one reason your water heater may be leaking is also the most obvious one—your water heater is old. Water heaters are only designed to last about 8 to 10 years. 

If your water heater is older, parts start to wear out, causing leaks. The water heater could also form rust in the tank, leading to small cracks that allow water out of the tank and into your home. 

Purchasing and installing a new water heater is the only fix for a water heater leaking due to old age. 

A Valve may be Broken 

Water heaters have several valves, from drain valves near the bottom of the tank to valves that measure the temperature and tank pressure. 

When these valves break, water leaks from the sides of the tank or below the tank. The good news is that replacing a faulty valve can solve the issue. 

The Connecting Lines are Loose

There are two connecting lines on a water tank, one for the water entering the tank and another for the water leaving the tank. These valves can become loose over time and cause leaks. 

When this happens, you will likely see water dripping from the area where these lines connect to the tank. Sometimes tightening the lines to stop water from leaking will solve this issue. However, in other instances, the lines are worn and will need to be replaced to stop the leak. 

You Have Sediment Build-Up 

Water entering your water heater often contains sediments, and in some areas with hard water, like Southern California, these sediments can build up quickly. When too much sediment accumulates, cracks form in the tank causing leaks. 

Once you have a sediment build-up problem, you will need a professional to fix this leak. To prevent sediment build-up leaks, drain and clean your tank regularly. 

What to Do When Your Water Heater is Leaking

Regardless of whether or not you know why your water heater is leaking, it’s important to address the leak right away. Water heaters hold a lot of water, and a small crack in the tank can quickly grow and cause massive damage to your home.
