Why do water heaters fail?

Read Time:4 Minute, 5 Second

Main reasons water heaters fail

The main reasons water heaters fail are:

  • Sediment buildup
  • Faulty TPR valve
  • Broken heating element
  • Too much pressure
  • Leaking
  • Inadequate maintenance

Sediment buildup

Sediment buildup is the most common reason water heaters fail. Over time, sediment builds up in the bottom of the tank and can clog the heating element, leading to failure. A faulty TPR valve can also cause water heater failure. This valve is responsible for releasing pressure from the tank, and if it is not working properly, the pressure can build up and cause the tank to burst.

Broken heating element

The heating element is responsible for heating the water in the tank. If this element breaks, the water heater will not be able to heat the water, causing it to fail. Too much pressure in the tank can also cause the heating element to break.

Leaking

A water heater can fail if it starts to leak. This can be caused by a number of things, including a faulty TPR valve, a cracked tank, or sediment buildup. If your water heater is leaking, it is important to have it repaired or replaced as soon as possible to avoid further damage.

Faulty TPR valve

The TPR valve is responsible for releasing pressure from the tank. If this valve fails, it can cause the tank to overpressurize and leak.

Cracked tank

A water heater can fail if the tank becomes cracked. This can be caused by a number of things, including sediment buildup, corrosion, or overheating. If your water heater’s tank is cracked, it is important to have it repaired or replaced as soon as possible to avoid further damage.

Overheating

If the water in the tank overheats, it can cause the tank to crack or leak. This can be caused by a number of things, including a faulty thermostat, a broken heating element, or sediment buildup. If your water heater is overheating, it is important to have it repaired or replaced as soon as possible to avoid further damage.

Corrosion

Corrosion can also cause a water heater to fail. This happens when the metal of the tank starts to break down and deteriorate due to exposure to water and other chemicals. This can be caused by a number of things, including high water hardness, improper pH levels, or the use of chlorinated water. If your water heater is corroding, it is important to have it repaired or replaced as soon as possible to avoid further damage.

Inadequate maintenance

Another reason why water heaters fail is due to inadequate maintenance. This means that the tank is not being cleaned and flushed on a regular basis, which can lead to a build-up of sediment and other debris. Over time, this can cause the metal of the tank to break down and deteriorate, eventually leading to a failure. It is important to have your water heater serviced on a regular basis to avoid this type of problem.

There are a number of reasons why water heaters fail. These include corrosion, sediment buildup, overheating, and inadequate maintenance. If your water heater is having any of these problems, it is important to have it repaired or replaced as soon as possible to avoid further damage.

Signs that your water heater is about to fail

Signs that your water heater is about to fail include leaking, strange noises, or reduced water pressure. If you notice any of these problems, it is important to call a plumber right away. A qualified technician can diagnose the problem and recommend the best course of action.

If your water heater is beyond repair, it may be time to replace it. There are a number of different types of water heaters on the market, so it is important to choose one that will meet your needs. A key consideration will be water heater replacement cost.

How to prevent your water heater from failing

There are a few things you can do to help prevent your water heater from failing. These include:

  1. Flushing the tank on a regular basis. This will help to remove any sediment and debris that has built up over time.
  1. Checking the temperature of the water heater on a regular basis. If it is set too high, this can cause the metal to overheat and break down.
  1. Regularly servicing the water heater. This will help to identify any problems early on and prevent them from becoming worse.
  1. Replacing the water heater if it is more than 10 years old. Even with proper maintenance, water heaters have a limited lifespan and will eventually need to be replaced.

If you follow these tips, you can help to prevent your water hea from failing. However, if it does fail, it is important to have it repaired or replaced as soon as possible. Water heaters are an essential part of any home and should not be left in a state of disrepair.
