He didn’t think water creates pressure naturally, and a water heater can become damaged after a buildup of pressure if too much steam is in the tank, the water can leak through cracks and other loosened parts sometimes if extremely hot water is coming from the water heater for an extended amount of time it can damage the tank it’s important to be aware how much hot water you’re using and how much maintenance you’re giving your water heater.

Relief Valve

Every water heater has a drain called a relief valve which is the only way that water should be able to come out of your water heater. You can use this valve to empty sediment and contaminated water. If the drain valve is loose, it will begin to leak water. A loose drain valve is an easy fix because if you have a wrench in your home toolbox, all you have to do is tighten the drain valve, but if the leak is from the base of the relief valve, that means it is not tight enough, and it will require a new drain valve if you feel uncomfortable performing this task you can always ask a plumber to tighten or replace the drain valve for you.


There are two pipes on top of your water heater. Inspect them, and you may see loose or damaged. They are your cold water inlet pipes and your warm water outlet pipes. If they have become fitted incorrectly or lost, this could be where the leak comes from. Loose pipes are easy to fix with your wrench.
Any other pipes connected to your water heater may also have loose connections and may spring a leak. If you have tightened all your pipe connections and the leak does not stop, you may have to replace pipes. A plumber can replace or repair pipes for you as well.


Whenever the water heater uses heat, the water will expand, and over time, this creates stress on the water heater tank and its components; sometimes, it can even cause cracks to form on the tank or other components. Also, if you have sediment buildup in your tank, this will cause cracks. If any components on your water heater have become damaged, you will need to replace the water heater.


Unfortunately, water heaters are not immortal. They have a lifespan like any other appliance. The older your tank is, the more likely you are to gain leaks and over time, the water heater will deteriorate, especially if you use a lot of hot water. Try to monitor your usage of hot water to lengthen the lifespan of your water heater and beyond the lookout for any rest that has developed over the time that you’ve had your water heater. If your water heater is at the end of its lifespan, consider replacing it to avoid any contamination in your water or any severe water damage to your home.

What Should You Do First?

Investigate the Leak

After you’ve called your local and trustworthy plumber to fix your water heater, you might try investigating why the water heater decided to leak. Look at the exterior of your water heater and appliances. Make sure your AC isn’t leaking or your furnace. Put paper towels on the ground to test which direction the water is coming from.

Turn off the Power

Once you make sure that it is the water heater leaking, turn off the power. You should never work on your water heater while hooked up to any electricity or power source. If you have an electric water heater, flip off the switch in your circuit breaker to turn off the power and continue safely. If you have a gas water heater, there is a gas shut-off valve at the base of your tank near its gas line dedicated to turning off the power.

Shut off Cold Water Supply

Remember that your water heater has two pipes connected to the top of its tank. These two pipes are where the water supply comes from, and blue or red switches often designate it. If the switches are not color-coded, you can simply feel which one is hot or cool to the touch and turn off the shut-off valve as far as possible to turn off the cold water supply.

Diagnose the Leak

The first step to diagnosing the leak of your water heater is to find the exact location of the leak on the tank or components. Look at the top in the middle at the base and on all the surrounding attachments to locate any cracks, loose connections or other issues. If you find damage like a crack, you must replace your water heater. If it is a loose component, it is possible that simply tightening the component will fix the problem.

Schedule Water Heater Repair

Now is the time to ask for help from an HVAC or plumbing pro. Sometimes, there is just no DIY fix for a water heater issue; a professional will either be able to return your water heater to functioning order or suggest that you replace the water heater.
