Common Causes of Water Heater Leaks

If you notice that your water heater is leaking, there are several common causes that you should be aware of.

The first possible cause of a water heater leak is a faulty temperature and pressure relief valve. This valve is designed to release excess pressure and prevent the tank from exploding. If it malfunctions, the pressure inside the tank can build up and cause leaks.

Another common cause is a worn-out drain valve. Over time, this valve can become loose or corroded, leading to leaks.

Additionally, a water heater leak can be caused by a cracked or damaged tank. This can occur due to age, corrosion, or excessive pressure.

Lastly, a leaking water heater may be the result of loose or damaged pipe connections. If the connections aren't properly sealed or tightened, water can seep out and cause a leak.

If you notice that your water heater is leaking, it's important to take immediate action to prevent further damage. First, turn off the power supply to the water heater to avoid any electrical hazards. Next, shut off the water supply to the tank. Finally, contact a professional plumber to assess and repair the issue.
