5 Common Signs of Water Heater Problems


Did you know that water heating accounts for around 20% of your home’s energy use?

A significant source of heat in American homes is electric water heaters. The only thing is that when water heaters break down, there can be some critical issues. You risk the health and safety of yourself and your family.

When a water heater is not working, there are some common signs that you need to look out for. This post will tell you about water heater problems and some ways to identify them.

The more you know about your water heater and its signs, the better you can prevent a catastrophic and risky failure.


1. Strange Noises

Strange noises from a water heater can be a common sign that it is having some problems. While these usually indicate that parts have gone wrong and need to be replaced, they can also be indicators that something more serious is wrong. If your water heater begins making loud noises or buzzing, it could indicate excessive pressure in the tank or within the pipes.

Excessive pressure can cause leaks, cracks, and bursts, so it is essential to get it checked out quickly. It is also possible that the noises come from a loose part or insulation, meaning it needs to be tightened up or replaced to prevent further damage.

2. Inconsistent Water Temperature

If users notice that water temperature varies sporadically, it could be because the water heater is not adequately mixing warm and cold water. In some cases, the issue might be linked to malfunctioning thermostats or poor insulation. Additionally, it is possible that the elements in a tank-style water heater have become corroded and can’t adequately heat the water as needed.

3. Rusty or Cloudy Water

When a water heater is on its last legs, it can cause the tank to rust from the inside out, leading to dark brown and rusty water entering the plumbing system and, eventually, your water fixtures. Similarly, when hard water and sediment enter the porcelain tank, it can cause a white, cloudy color to appear when running hot water.

In either case, this indicates that it is time to replace your water heater. Other signs of a faulty water heater include loud rumbling noises, lack of hot water, and a leaking tank caused by pressure buildup.

4. Leaking

Leaking is one of the most common signs of water heater problems. If there is any trace of moisture around the base of the heater, there’s likely a serious issue that needs to be addressed. Leaking can also mean a problem with the pressure relief valve, faulty pipe connections, a cracked tank, and even an inaccurate temperature and pressure relief valve.

5. Aging

As sediment builds up inside the tank and begins to heat up, it can cause the water heater to make loud popping, rumbling, or high-pitched noises. As water heaters age, they can also become less effective at delivering hot water or stop producing hot water altogether.

If you consider water heater care for the future, look for water heater repair.

Understanding Water Heater Problems

If any of these common signs of water heater problems are present in your home, it is essential to consult a professional for help. Don’t try to repair it on your own – it is always best to have an expert evaluate your water heater and make any necessary repairs or replacements.
