Common Reasons for Water Leaking Electric Heater Issues

January 15, 2025

Electric water heaters are important in many homes. They give hot water for cooking, cleaning, and bathing. Sometimes, these heaters can leak. 


This can be a hassle and may cause water damage. 


By knowing what causes water leaks in electric heaters, homeowners can take steps to prevent issues and get repairs done on time.

Common Causes of Water Heater Leaks

Faulty Temperature and Pressure Relief (TPR) Valve

The temperature and pressure relief valve is an important safety part of an electric water heater. Its job is to let out water if the pressure or temperature in the tank becomes too high. A broken or poorly placed TPR valve can lead to leaks. Checking and taking care of the TPR valve regularly can help stop leaks and make sure your water heater works safely.


Sediment Buildup in the Water Heater Tank

Over time, bits from minerals in the water can build up at the bottom of the tank. This build-up can cause the tank to overheat and weaken its lining, which may lead to leaks. Regularly flushing the tank helps clear out these bits. This practice can make your water heater last longer and lower the chances of leaks.


Corroded Anode Rod

The anode rod picks up harmful elements in the water. This action helps keep the tank safe from rust. If the anode rod gets fully corroded, it cannot protect the tank anymore. This could cause leaks. Check your water heater every year. Make sure the anode rod is in good shape and change it if needed.


Loose Pipe Connections

Loose pipe connections can make water leak from the top or sides of your electric water heater. You can use a pipe wrench to tighten these connections. But, if the connections are badly damaged, you might need a professional to replace or fix them.


Cracked Storage Tank

The inner lining of the storage tank can crack because of age, high water pressure, or defects in how it was made. If you see water leaking from the bottom of your electric water heater, it could mean the tank is cracked. In this situation, replacing your water heater is usually the best idea.


Excessive Water Pressure

High water pressure can put a lot of stress on the water heater tank and its parts. This tension can cause leaks. A pressure-reducing valve can help control the water pressure and stop leaks before they start. Checking your system regularly can also help make sure it works well within safe pressure levels.


Damaged Drain Valve

The drain valve is used to empty the tank. A valve can loosen or get damaged as time passes, which causes leaks. You can fix this issue by tightening or replacing the valve.

Frequently Asked Questions

  • How do I know if my water heater is leaking?

    Check for any signs of water at the bottom of your heater or dripping from the pipe connections. Make it a habit to look at your water heater often for wet spots or rust.

  • What should I do if my water heater is leaking?

    Turn the power supply off and shut the valve that controls the water flow to the heater. Contact a plumber to find the source and fix the problem.

  • Can sediment buildup cause a water heater to leak?

    Yes, the buildup of sludge can cause overheating. It can also damage the tank lining and lead to leaks. Regularly flushing the tank helps stop sludge from building up.

  • Is it better to repair or replace a leaking water heater?

    If the damage is local, like a broken valve or a loose pipe, fixing it may be enough. But if there is major damage, like a cracked tank, you will likely need to replace your water heater.
