A leaking water heater is one of those problems that may start quietly with a small puddle near the tank. It might not seem urgent initially, but a leak is never something to ignore.
Even small drips can indicate bigger issues. Over time, a leak can damage your flooring, raise your energy bills, or even lead to system failure.
Here are a few reasons your water heater might be leaking—and what you can do next.
1. Loose Connections or Fittings
Sometimes, the leak isn’t from the tank but the connected pipes. Over time, loose fittings or worn-out seals can allow water to escape slowly. This issue is common in older systems or those exposed to years of vibration during regular use.
2. Tank Corrosion
If your tank is rusting from the inside, it’s only a matter of time before small leaks become more serious. In many cases, corrosion means it’s time to start thinking about a water heater replacement, especially if the unit is over ten years old.
3. Faulty Pressure Relief Valve
Your water heater has a pressure relief valve to release excess pressure or temperature. If this valve is faulty or stuck open, it can cause water to leak. Sometimes, a simple valve repair is enough to fix the problem, but a full inspection is the best way to determine the exact cause.
4. Drain Valve Trouble
At the bottom of your tank is a drain valve for maintenance and flushing. If it’s not fully closed or starting to fail, it can create a slow leak that worsens over time.
