Why Is My Water Heater Leaking?

A leaking water heater should never be ignored. Sometimes, it’s a minor issue, but it can often lead to a broken water heater and a huge mess. No matter what, be sure to find the source of the leak and get it fixed as soon as possible.

Reasons a Water Heater May Leak

Standard water heaters hold dozens of gallons of water, ready to be used when any hot water faucet is turned on. There are ample opportunities for these containers to leak. A few reasons you may experience a leaking water heater include:

  • A broken or clogged water intake or output line: Water has to be able to enter and exit a water heater. If the input or output pipes are clogged, dripping at the connection points may occur.
  • A malfunctioning pressure relief valve: Water heaters are under a lot of pressure due to the changing temperature of the water inside the tank. A pressure relief valve may let out some pressure and water to ensure the safety of the tank.
  • A degrading water heater container floor: Water heaters can collect debris and chemicals at the bottom of the tank for years. These chemicals can degrade the metal floor of the tank, leading to significant damage and loss of water.
  • An open water heater drain valve: Water heaters feature a drainage valve for situations when the entire tank must be emptied. If this valve is open even slightly, water will pour out.

In some of these situations, a simple turn of a knob can solve the issue. In other instances, it’s vital that you call a plumber before the problem gets worse.

Major Issues for Leaking Water Heaters

Ignoring a leaking water heater is always a bad idea. If the leak is due to a failing water heater, you need to have it repaired or replaced as soon as possible.

If a water heater keeps leaking due to damage, all the water inside the tank could leak out. This can cause a huge mess around the water heater itself and lead to floor damage and mold development.

Many water heaters are situated on top of a drip pan that drains outside the home. However, if the entire contents of a water heater pour out quickly enough, the drip pan won’t be able to deliver the water to the outside fast enough.

What To Do When Your Water Heater Leaks

If you suspect your water heater is leaking due to a malfunction, takes these steps to avoid further issue:

  • Turn off the water supply: Find the supply valve for the water heater and turn the knob or handle to stop the flow of water into the tank.
  • Turn off the power supply: Find the power switch or button for the water heater and switch it to the off position.
  • Call a plumber: Make sure you call a professional to identify the exact cause of the leak. A plumber can resolve the issue in full or replace the water heater if necessary.
