A water heater is one of the most important appliances in a home. It provides hot water for showers, laundry, and dishes. But like all appliances, it will eventually fail.
Knowing the warning signs can help you prevent water damage, a costly breakdown, or no hot water at all.
- Water is Warmer than Normal
It’s easy to take your water heater for granted until it stops working. If you’re experiencing a lack of hot water or strange odors coming from the tank, it may be time to replace your unit.
Fix-It Right Plumbing, the best plumber in Melbourne might tell you that a water heater that takes longer than usual to heat up is often a sign of sediment buildup. Over time, sediment builds up and insulates the heating element, causing it to work harder. This can lead to rust and corrosion of various metallic parts within the tank.
Other warning signs include a rotten egg smell or a metallic taste. These can indicate that the magnesium-style anode rod has begun to corrode. If left unchecked, these problems can lead to a leaky water heater or even a total failure.
- Water is Rusty or Yellow
When your water heater is failing, it may start to produce rust-colored or yellow water. This can indicate a problem with the anode rod or a buildup of sediment in your tank. Rust-colored water can also be caused by a leak or perforation in your tank wall. Promptly addressing these issues can help prevent further damage and save you money on a new water heater.
If you notice that your hot water is lukewarm instead of hot, or that it takes longer than usual to warm up, this could be a sign that there is a problem with the heating element or thermostat. These problems can be fixed by flushing the water heater or having a professional inspect and repair them. These steps can help you save money on a replacement and ensure your family has consistent, high-quality hot water for years to come.
- Water is Colder than Normal
If you’re getting lukewarm water despite having your shower handle set at the highest temperature setting, this may be a sign that your water heater is nearing its end of life. This is because sediment buildup insulates the heating element, making it harder to warm up your water.
Additionally, sediment can cause your water heater to make strange noises. These noises are caused by mineral deposits or air pockets in the sediment layer. This is also a clear sign that you should start considering a new water heater. It’s better to replace the unit before it starts leaking and floods your home. You can avoid this
issue by draining your water heater at least once a year. This is a relatively easy process that you can do yourself.
- Water is Cloudy or Smelly
If your hot water is murky and accompanied by a strange odor, it’s time to call in a service professional. This problem is a sign that sediment has begun to build up on the tank’s bottom. Eventually, this stress can cause the water heater to begin to leak.
This odor is caused by sulfates reducing to hydrogen sulfide in the water. This gas is most commonly found in sewers, septic systems and volcanoes, but it can also come from older water heaters that don’t maintain the high enough temperature to kill bacteria.
It’s important to keep an eye on the age of your water heater so you can plan for repairs or a replacement as it approaches its typical lifespan. A quick glance at the serial number can help you determine the date of manufacture.
- Water is Noisy
Humming and crackling noises are normal for water heaters, but if they become louder or more frequent it means something is wrong. The hum may be caused by mineral deposits or sediment at the bottom of your tank, which can cause excess pressure and a possible explosion. You should flush your tank regularly to prevent this. Humming could also be a sign of a leaking temperature and pressure relief valve or loose heating elements that need tightening.
Rumbling and banging noises are a sure sign that it’s time to call a plumber for a water heater replacement or repair. These sounds indicate that your water heater has a serious leak or is close to failure. This can lead to a flooded basement, damage to your home’s pipes and other costly problems.
