The leading causes of water heater leaks include:

  1. Broken drain valves: These will cause water leaks from the bottom of the tank. They’re easily fixed by replacing the broken drain valve.
  2. Corrosion: Sediment buildup can cause corrosion, cracking, and holes in the bottom of the tank. When this happens, it’s usually time for water heater replacement.
  3. Loose water line connections: Normal wear and tear can loosen the inlet or outlet water lines, causing leaks. This problem can usually be fixed by tightening or replacing the loose, worn water lines.
  4. Broken temperature/pressure valves: As their name suggests, these valves monitor and regulate the temperature and pressure inside water heaters. When they break, they can cause water leaks from the sides of a water heater tank.

Of course, various other things can cause water heater leaks—and, sometimes, these leaks are the result of multiple issues. The best way to determine what’s causing your water heater leak and get the best solution for fixing it is by contacting a professional, like the trusted plumbers at Plumb Medic.
