Cold water is great until it’s time for that hot shower. If your water heater goes out, you’ll have no hot water for showers, dishes, or laundry. Fortunately, there are some tell-tale signs of water heater failure that are easy to spot. A few of them are listed below to help you determine whether or not you need a new unit.

It’s Old

Your water heater will not magically last forever. If you have an old one, then chances are it might need replacing soon. Units that are more than 15 years old most likely are on their last legs and worth replacing before they stop working.

Little to No Hot Water

When water heaters are about to fail, they slowly start producing less hot water. It is a clear sign that there is a problem you should address before the unit goes out. If your unit isn’t providing any hot water whatsoever, then it is probably dead, and contacting a professional experience in water heater installation in San Mateo, CA, is a good idea.

Unusual Noises

Every appliance makes some noise when it is in use. However, if your water heater is making new noises, then you may have an issue. You might want to check that it’s sitting correctly, or for more peace of mind, call in a pro experienced in water heater installation in San Mateo, CA.


Water heaters must be completely free of leaks and cracks, or you risk damaging your house. Check to see if there is water pooling below your unit. If there is, then you probably have a crack in the tank, and you should have a professional replace it immediately. Water heater tanks carry an immense amount of water. If your leak continues, the crack will get larger, and eventually, all of this water could end up flooding your home.
