Understanding the Drain Valve: A Culprit in Disguise

The drain valve of your water heater is a small yet crucial component. Located near the base of the tank, it serves the purpose of periodically flushing out sediment and minerals that accumulate at the bottom. Over time, this sediment can lead to reduced efficiency and potential damage to the tank.


However, when the drain valve itself starts leaking, it's time to take action.


Common Causes of Drain Valve Leaks


  • Loose or Faulty Valve: One of the most straightforward reasons for a leak is a loose or defective valve. This can happen due to wear and tear over the years, causing water to escape from the valve connection.

  • Sediment Buildup: Ironically, the very sediment that the valve is meant to flush out can also contribute to leaks. Excessive sediment accumulation can cause the valve to become clogged or corroded, resulting in leakage.

  • Excessive Pressure: High water pressure is another potential cause of leaks. If the pressure inside the tank becomes too much for the valve to handle, it might start leaking to release the excess pressure.
