Your water heater is built to last, but that doesn’t mean it won’t have problems from time to time. But how do you know if there’s something wrong with your water heater? Understanding the subtle signs that something is wrong can help you address repair needs before they cause big problems for your home.

If you think you need water heater repair in Woodbridge, NJ, our team can help. In the meantime, you can keep reading to learn more about how to know if you need water heater repair. Keep in mind that even if you have a tankless water heater, you still may run into problems from time to time.

Lack of Hot Water

If you get in the shower or go to wash dishes, only to be met with lukewarm water, something is wrong with your water heater. First, you should check the thermostat settings on your water heater to make sure that the temperature is high enough. Increase the temperature some, but no higher than 120°F, and see if it makes a difference. 

If you still have lukewarm water, there may be a problem with the gas igniter or electric heating element, depending on what type of water heater you have. You could also have an issue with the thermostat. No matter what the problem is, our team can fix it. 

Unusual Sounds

Aside from hearing water run, you shouldn’t hear any other sounds coming from your water heater. If you hear anything popping or knocking, there may be sediment buildup at the bottom of your tank, which comes from hard water that is high in mineral content. Thankfully, this is an easy fix. You just need a plumber to flush out your system. Ideally, you want to schedule the service annually to prevent the sediment buildup from damaging your gas igniter or electric heating element.

Discolored Water

If your water is discolored, it may be from the inside of your water heater. Turn the cold water off completely and just run the hot water. Is the water discolored? Then do the opposite. Turn off your hot water and only run your cold water. If the hot water is the only one that is discolored, there’s a good chance that your water heater is to blame. If both your hot and cold water are rust-colored, the problem is somewhere else in your plumbing.


You may think that leaks are common, since they are pipes connected to your water heater. But your water heater should be completely airtight and never leak. If you see water dripping out from any of your water heater’s connections, it’s important to get the problem addressed right away. A leak can cause damage to your home and can also cost you more on your monthly water bill.
