3 Warning Signs Your Tank Water Heater Needs Repairs

The most common type of water heater found in homes is the familiar tank water heater. There are many great alternative options for new water heaters today (such as tankless and heat pump models), but if you still have a tank water heater, you’ll want to make sure that it lasts for as many years as it can before you need to think about a replacement.

A big part of ensuring that a water heater endures for as long as possible is to arrange for repairs the moment the system needs them. It can be tricky to notice some water heater problems, so we’ve provided a list of 3 common signs to watch for:

ONE: A drop in hot water volume

Don’t ignore a decline in the amount of hot water your home gets, since this is one of the first signs that the water heater is losing its abilities. If people in your home are starting to go with lukewarm or cold showers in the morning when this previously never happened, the water heater needs to have professionals investigate right away.

TWO: Rumbling sounds from the tank

This sound doesn’t mean that your water heater’s tank is about to burst—but it’s still something to pay attention to. There are some different reasons for this to start: a broken dip tube allowing cold and hot water to mix at the top of the tank, sediment gathering at the tank bottom, and a spike in water pressure. Leave it to professional repair technicians to find out what’s wrong and how to fix it.

THREE: Signs of corrosion on the tank

Corrosion is a major danger for water heaters, and if you see any indication of it starting on the tank, call for repairs immediately. If caught in time, technicians can sometimes replace the affected parts; otherwise, the whole tank may need to be replaced.
