A water heater is a household appliance that heats water for bathing, washing dishes, and other purposes. The water is heated in a cylindrical tank with metal coils or heating elements inside. If you have a leaky water heater, it’s important to find out what’s causing it and get it fixed as soon as possible. Keep reading to learn more about the most common causes of water heater leaking.

Poorly Aligned or Damaged Burner Assembly

Poorly aligned or damaged burner assemblies are one of the most common causes of water heater leaks. The burners in these assemblies must be properly aligned and undamaged in order to create an effective flame; otherwise, the excess heat can cause damage to the water heater tank.

Broken Tank Weld

Another common cause of water heater leaks is a broken weld. If the welds on the tank are not strong, they can break and cause a leak. This is a particularly common problem with older water heaters. If your water heater is more than 10 years old, you may want to consider getting a new one, especially if you’re experiencing leaks.

Worn-Out Gasket

The gasket is the seal that sits between the tank and the cover, and if it wears out, it can allow water to leak out. You can usually tell if the gasket is the problem if the leak is coming from the top of the water heater. If this is the case, you can usually fix the problem by replacing the gasket.

Broken Flue Pipe

A broken flue pipe can cause all sorts of problems in your home, from water damage to dangerous gas emissions. If you notice that your flue pipe is cracked or broken, you should call a professional immediately to have it repaired. A broken flue pipe can allow water and debris to enter your home, which can lead to extensive damage. Additionally, a broken flue pipe can allow carbon monoxide and other dangerous gases to escape from your home, putting your family’s health at risk. It is important to have a broken flue pipe repaired as soon as possible to avoid any of these problems.

Rust and Sediment Build-Up

The inside of a water heater is susceptible to rust and sediment build-up over time, especially if the water heater is not properly maintained. If these deposits accumulate on the bottom of the tank, they can create a leak. In addition, the metal in a water heater can corrode over time, which can also lead to a leak.

Faulty Valves

The valves on a water heater can become defective over time, leading to leakage. If you are unsure whether or not your valves need to be replaced, contact a qualified plumbing professional for assistance. They will be able to inspect your water heater and valves and make a recommendation based on your specific needs.

Inadequate Insulation

The insulation around your water heater keeps the heat in, which will help your water heater to run more efficiently. If your water heater is not properly insulated, it may become too hot and start to leak. There are a few ways that you can insulate your water heater. One way is to use a water heater blanket, which is an insulation blanket that can be wrapped around your water heater. Another way to insulate your water heater is to use fiberglass insulation, which can be placed in the spaces around your water heater. A professional plumber can make recommendations and ensure your water heater is insulated correctly.

Overall, water heater leaks can be caused by a variety of factors and can lead to extensive damage if not addressed in a timely manner. It is important to be aware of these potential causes and take steps to prevent them, as well as having a plan in place for addressing any leaks that may occur.
