Water heaters can last a long time, but even the best ones can leak. A leaking water heater doesn’t automatically mean you need to replace it. However, you’ll want to fix any leaks as soon as possible. Small leaks are a minor nuisance and are easily handled before damage is done. However, this small leak will soon become a greater threat of causing a more severe problem if not repaired quickly by a licensed plumber. Here are four common causes for a water heater leaking.

4 Common Causes for a Water Heater Leaking

Heater Drain Valve

Water heaters leak for several reasons. One of the first things the plumber will check is the drain valve. If this is the location of your leak, it’s good news. Leaks from the drain valve are inexpensive and a quick fix.

If the water leak is coming from the drain valve, make sure it’s completely closed. If it continues to leak, you may need to replace it.

The Bottom of the Water Tank

If it’s not the drain valve, the next place your plumber will inspect is the tank itself. Leaks sourcing from the bottom of the tank isn’t good news. Sediment built up over the years will eventually erode through the bottom of the tank and begin to leak. If age and deterioration are the cause of the leak, you’ll need to call a professional plumber to replace the water heater.

You can inspect these areas before contacting a plumber. While these are the two most common causes of water heater leaking, they aren’t always the case. Below are two more that could be causing the leakage.

The Cold and Hot Water Inlet and Outlet Connections

If the cold water and hot water inlet and outlet connection is the cause for your leak, then it’s a very easy fix. Check to see if the connections are loose. If this is the cause, then all you’ll need to do is tighten the connection with a wrench or replace a faulty pipeline.

Temperature and Pressure Relief Valve

  • Too much pressure within the tank, causing it to force the water out through the T/P valve to prevent a more significant problem from occurring.
  • Water that’s too hot.

If this is the source of your leak, it’ll cause water to run down the side of your tank. Call a licensed plumber to help determine which of the above is the cause.
