water heater is leaking

Your water heater is an important appliance in your home, ensuring comfortable water usage during extreme winter months. However, like any other system or appliance, the water heater is also prone to damage and leakage. Water heater leaking can become a problem for many homeowners who are unaware of the method to fix it or find the exact reason for the leak. Here, the article will consider why your water heater may leak and the methods to solve the issue, including:

  • The Reasons For Water Heater Leakage
  • How to Solve A Water Heater Leakage
  • Does Home Warranty Cover Water Heater Leakage?
  • How much does water heater repair cost?

The Reasons For Water Heater Leakage

Your water can leak due to several reasons:

  • The drain valves of the water heater can break due to wear and tear. Once the drain valves have broken, they can not stop the water from leaking. As such, you may find water seeping out the bottom of your tank. The best way to solve this issue is by replacing the drain valves.
  • Corrosion is a major reason for water heater leakage. Over time, the water heater may get corroded with sedimentary deposits building at the bottom of the heater. As such, the heater may have holes and gaps that let the water out. The best replacement for corrosion-based water heater leakage is to replace the water heater.
  • Waterline connections can lose over time due to wear and tear. Due to the loosened connections, the leak may become frequent. The best remedy is to tighten the water lines. However, if the lines have serious damage, they may have to be replaced altogether.
  • In some cases, the temperature and pressure valves may become broken. These valves control the inflow and outflow of water from the water heater. If these valves get broken, you may need a complete replacement of your water heater.

However, these reasons are not the only ones that can cause a water heater leakage. Instead, the leakage may occur due to multiple other problems. The best way to diagnose the exact issue is by hiring a trained professional for the diagnosis.

How to Solve a Water Heater Leakage

In case your water heating is leaking, you need to follow the following steps:

  • First, remove the source of power from the water heater. Otherwise, the water inside can be very hot and may make it difficult to work on the water heater’s inside. If you are using a gas water heater, there will be a thermostat installed. Use the thermostat to switch off the water heater completely. If you use an electric water heater, you need to turn off the electric supply to ensure full safety completely.
  • Once the power supply is removed, it is important to remove the water supply as well. Turn the water supply off directly from the waterline leading to your system. 
  • Drain the water in the water tank of the heater. It is important to drain the water to work on the insides of the water heater. First, use the drain valve at the bottom of the heater to remove most of the water. Similarly, drain the water using a sump pit. Finally, you will also need to break the vacuum as well. Air must enter the hot water faucet for the system to work properly.

Does Home Warranty Cover Water Heater Leakage?

Most home warranties cover your water heater system. In case there is a water heater leakage, contact your home warranty company right away. They will send over a technician to judge the issue. Pay the service call fee and file the claim. If the claim is paid, you will have to cover only the balance amount for the repair and replacement.

Having a home warranty coverage for your water heater significantly reduces the cost of water heater leakage repair and replacement. Additionally, the same home warranty package can cover your other systems and appliances as well.

How Much Does Water Heater Repair Cost?

The water heater repair prices vary based on the type, make, model, and size of your water heater. Usually, an ignitor issue can be repaired for under 500 USD for most mid-size water heaters. However, a complete replacement may cost a lot more. Similarly, you may need to pay for the mineral deposit removal if you do not have a home warranty to cover the expense. This removal can cost between 150 USD to 450 USD, depending on the level of sedimentary deposit and the size of your water heater.

Other costs may include replacing the expansion tank, circular pump, and fixing the pipe leakages. However, the exact cost will be determined based on the exact condition and the subjective factors related to your water heater system.

Conclusion

Replace your water heater system if the leakage is persistent and is causing a lot of trouble.
