A water heater is a vital appliance that we rely on daily to provide hot water for our daily needs. From taking a bath, to using the dishwasher or washing machine, a water heater is essential. It’s important to pay attention to your water heater and notice the signs that it may be struggling. Instead of waiting for it to completely fail, recognizing the symptoms early can save you from a cold shower and unexpected repairs. In this blog post, we’ll discuss the signs to look out for when your water heater is struggling.

No hot water

One of the most obvious signs that your water heater is struggling is when it stops providing hot water. This can be caused by a variety of issues, including a broken heating element, a faulty thermostat, or sediment buildup in the tank. While it may seem obvious, many homeowners ignore the problem and try to cope by taking shorter showers or boiling water on the stove. If your water heater isn’t providing hot water, it’s time to call a plumber and have the issue resolved.

Strange noises

Another sign that your water heater is struggling is when it makes unusual noises. A properly functioning water heater should operate quietly. If you hear knocking, cracking, or popping sounds coming from your water heater, this may be a sign of sediment buildup or a failing heating element. Left unchecked, this can lead to complete failure or even a dangerous explosion.


If you notice water leaking from your water heater, this is a problem that needs to be addressed immediately. Leaks are a sign of a failing water heater and can lead to extensive damage to your home. Even a small leak can cause mold or mildew growth and damage to your floors or walls. Call a plumber as soon as you notice any leaks to avoid a costly repair.

Rusty water

If you notice that the hot water coming out of your faucets is rusty or discolored, this is a sign that your water heater is struggling. Rusty water is caused by rust and sediment buildup inside the tank. It’s a clear indication that your water heater needs to be flushed or replaced.


Finally, the age of your water heater is another sign that it may be struggling. A typical water heater lasts between 8-12 years. If your water heater is older than this, it’s time to start thinking about a replacement. Even if it appears to be functioning properly, an older water heater is more likely to fail and can lead to unexpected repairs or even a flood.


Your water heater is an important appliance that requires attention and maintenance. While some symptoms may be subtle, it’s important to recognize the signs that your water heater is struggling. If you notice any of the signs discussed in this post, call a professional plumber to diagnose and resolve the issue. Don’t wait until it’s too late and you’re left without hot water or facing costly repairs. Keep an eye on your water heater and take action at the first sign of trouble.
