How To Tell If I Need My Hot Water Heater Replaced

Your hot water heater provides the luxury of hot water but it is never seen. It is usually placed in a closet or in the attic and you trust that it is doing its job.  But how can you tell if your hot water heater is in need of repair, replacement, or just needs a pilot relight?

The obvious sign that your water heater is no longer effective is a reduction in hot water. That does not mean it necessarily needs to be replaced. The most likely culprit to a lack of hot water is the pilot light. The pilot light can go out for reasons not related to the water heater itself. It could be a bad thermocouple, a repairable issue. A faulty thermocouple can be diagnosed when the pilot light will not stay lit, and it is a fairly easy, cost effective repair. Also, be sure to check your warranty information to see if your hot water heater is still covered under the manufacturer’s warranty.

Other Signs of a Broken Water Heater

Many of the other signs that your hot water heater may not be functioning properly are more obvious.

Water Line Corrosion: Corrosion build up on the outside of the lines coming to the water heater or leaving the water heater are signs the hot water heater is leaking or a past leak has occured. It is best to have an experienced plmber inspect supply and drain lines for leaks or potential corrosion of the lines.

Active Water Leaks: If you see water leaking from any of the pipes, valves or your hot water heater, it should be treated as an emergency to prevent any further damage to your hot water heater or home. If left alone, small leaks can become a larger issue and cause severe water damage to your home.

Leaking From The Bottom Of Your Hot Water Heater: This leak is a sign that your hot water heater needs to be replaced. This type of leak typically happens with hot water heaters that are older and have deteriorated over years of use.

Tankless Hot Water Heaters: What To Look For

Faulty Heat Exchanger: The most common reason a tankless hot water heater will stop producing hot water is the heat exchanger. Heat exchangers are easy to replace and most likely covered under a 10-year manufacturer warranty.
Error Code Notifications: Tankless water heaters will also flash an error code that will tell homeowners exactly what is wrong making the search for repair much easier.
