You and your family rely on a functioning water heater. Unfortunately, most people don’t know that their system is about to fail, until it does. Knowing when a service or replacement is needed will prevent an emergency situation. 

Here are some indicators that your water heater may be on its last legs.

1- You Hear Unusual Noises

Sediment builds up in the system when it is in use. You may be hearing clunking, banging and other noises. It may indicate that it’s time for a replacement, or a tank flush by a licensed plumber like the experts at PR Plumbing.

2- Your Water Heater Is Old

You will eventually reach the point where your water heating system is just too old and outdated to be saved. Whether it begins showing symptoms of its age, or not, it’s a good idea to replace it once a decade.

3- Your Heating Bill Is Rising

Hot water accounts for most of the heating energy used in your home. It’s a good idea to have your system checked to see if a replacement will be more cost-effective.

4- You Have Increasing Repair Needs

Are you regularly calling a plumber to work on your water heating system? Constantly paying for service calls will add up quickly. It may also mean your unit is nearing the point of being beyond repair.

5- You See Rusty Water

Water plus old metal eventually equals corrosion. If the system is still young, you could only need an anode rod replacement. If it’s late in the system’s life, it may mean that a replacement will be more cost-effective.

6- You See External Signs of Corrosion

Rust inside is a problem, but rust outside is a definite indication that you’ll soon have to deal with a leak. When you see rust on the outside of the heater, around the pressure release valve, you’re in urgent need of a replacement.


7- You See Water Around the Base

This is an obvious sign. Even small leaks can quickly become big problems. It may also mean that you will soon need pest control too, as insects and rodents are attracted to the excess moisture.

8- Your Anode Rod Is Spent

The anode rod is designed to attract all the rust and corrosion inside. At a certain age the rod will become completely eroded and unable to take the rust burden away from the tank itself. At this point it’s time for a replacement.
