Signs Your Water Heater Needs Repair


No matter what the temperatures are outside, no matter what season it might be, there is one heating system that you’ll always need working in your home, day after day. It’s the water heater! It’s easy to take this system for granted, just trusting that you’ll have hot water coming from the taps at all times.

When you consider the strain your water heater goes under every year—after all it’s working 365 days a year—you’ll understand that you cannot expect it to work 100% free from malfunctions. At some point, you might need to have your water heater professionally repairs, and it helps to know the warning signs that something has gone amiss. Read on as we uncover some of the signs that it’s time to give us a call for water heater repair.

Drop in Hot Water Volume

Have you noticed members of your household complaining about going without hot water in their morning showers? If this is a new thing for your home and there used to be enough hot water for everyone each morning, it means that the water heater is likely losing heating power. This is one of the most common indications that a water heater needs to be repairs or perhaps even replaced if it is 15+ years old.

Water Discoloration

If you turn on hot water taps and see rusty, brownish discoloration in the water, similar to what you may see in the water when you turn the faucets on after coming home from a long vacation, it probably means that there is too much sediment inside the hot water tank. It could also indicate corrosion, which we’ll talk about in a moment.

Rumbling Sounds from the Tank

This noise can be a bit alarming—is the tank about to explode?! Likely not, but it’s still not a sound you want coming from your water heater. This can be indicative of an increase in water pressure within the tank, sediment along the bottom of the tank, a broken expansion valve, or even cold and hot water mixing at the top of the tank due to a broken dip tube.

Water Leaks

There is one thing you never want to see occurring around your water heater tank—water pooling up. The only area you might see water drip from (and the only place where it’s okay to see water drip from) is the pressure relief valve. If you see water coming from any other area of the system, it’s a problem.


Water heaters are designed in a way that they should be able to resist corrosion for most of their service life. Of course, this is dependent on how well the system is cared for (it should be maintained once a year). If corrosion starts to appear on your water heater, it might be fixed by replacing the corroded component—like if it’s a heat exchanger. But more often than not, corrosion is an indication that it’s time to replace the system altogether.
