How to Fix a Leaky Water Heater

A leaky water heater can happen because of various reasons. You might have heard that a leaky water heater is a lost cause. The truth is that’s not always the case. It depends on where the leak is coming from and if it’s even leaking in the first place.

Here at My San Juan Capistrano we deal with with these kinds of plumbing issues everyday. In this post, we discuss the different kinds of water heater problems that cause leaking and how to fix them.

Water Spraying from Pipes

Your water heater has water supply pipes that bring water to the tank. Sometimes, these pipes become damaged or they loosen. When this happens, water will begin to leak or spray in all directions.

We recognize that this is an alarming situation, but it’s manageable. First, turn off the water to water heater to prevent further water damage. Then, wipe down the pipe and see if you can figure out where the pipe is damaged.

The next step is to call a plumber. Some people may try to patch a damaged pipe with plumber’s tape, but this isn’t a permanent fix.


Have you noticed beads of moisture on your water heater? The good news is that this isn’t a huge problem. In many homes, temperature changes and humidity issues can cause the water heater to sweat. Usually this happens when the temperature drops suddenly.

Homeowners who deal with this problem the most tend to have their water heaters in utility closets or in an area of the house where the air conditioning is being used. When the air cools off suddenly, this causes condensation. Remember, your water heater holds 40 gallons or more of boiling hot water.

Water Heater Leaks from the Bottom

Unfortunately, water heaters don’t last forever. They have a limited lifespan between 8 and 12 years. Once a leak develops from the bottom of a water heater, it’s time to replace the unit.

Some people attempt to manage small leaks by placing towels around the base of the unit to keep the water contained. This isn’t a sustainable action. Eventually, the leak will get worse and the bottom of the tank could give way. If this happens, your home could experience serious water damage and flooding.
