Water heaters are a boon to many Americans, allowing them to get hot water when they turn on a faucet. Although these water heating devices can last for many years, they may develop hiccups throughout their life.

While some water heater issues are repairable, others may call for a complete water heater replacement. If you get your hot water supply from a conventional storage water heater, here are a few common problems you may face with your water heater and their possible solutions. 

Sediment Buildup

Sediment buildup occurs when the natural minerals in your domestic water supply, like magnesium and calcium, settle at the bottom of your hot water tank. The minerals form an insulative layer that prevents efficient heating of your water.

As a result, you may encounter problems, such as inadequate water temperature, increased pressure buildup inside the tank, and spiking water heating bills. To resolve these issues, drain your tank to remove the accumulated sediment and refill it with fresh water.


Like other water-using devices, your water heater can develop leaks in the tank or piping that transports water to the various hot water fixtures in your home.

If you notice a leak in your hot water system, find and fix it before it causes extensive water damage to your home. Meanwhile, you should turn off the water supply to your water heater to stop the water from flowing and continuously leaking out. 

Water damage from water heater leaks may require expensive repair and remediation due to associated problems like mold growth. Acting fast when you have a leaky water heater can save you a lot of money on potential home repairs.


Your water heater has a long metal rod that extends through the interior of its tank. This metal rod is called a sacrificial anode and its primary purpose is to prevent corrosion of the tank's interior by attracting the minerals in your water supply. 

If you have rusty water, the sacrificial anode may be corroded and requires a replacement. If you fail to replace it, the rust can spread and result in the total failure of your water heater.

While routine servicing of your water heater will help ensure a reliable hot water supply in your home, unexpected problems can occur at any time. Contact a fully trained plumber for assistance if you notice or suspect any problem with your residential water heater.
