What are the signs that indicate a hot water tank needs to be replaced?

#1 If your hot water tank is old

#2 If you notice rust on your tank or in your water

Rust is very dangerous to steel because once corrosion hits the surface, it will gradually spread and eat through the material. Because of this, you can expect to have a few leaks in your water tank should you spot some rusty spots. Moreover, the rust can contaminate your water and cause a health hazard to your home.

#3 If your water tank makes noise

If your tank starts making noises, it could be due to sediment buildup. This can cause the water heater to brittle, function inefficiently, and consume more energy. This is why it is important to flush the tank out annually and drain the sediment below.

#4 If your water tank leaks

Apart from rust, another cause of leaks could be the expansions to the metal. With multiple heating cycles throughout a decade, the inner part of the tank starts to expand and form fractures.

#5 If your water is not heating

If you have double-checked your thermostat and heating element with both functioning fine, then it is most likely an issue with your hot water tank.

How long would it take to replace?

It would take an average of about 2 to 3 hours to replace a hot water tank.

The first part involves draining, disconnecting, and removing the old one, which would roughly take 45 minutes to an hour. The remainder of the time will be spent bringing the new tank in, fixing it to the exact spot, connecting it to a power or fuel source, any venting steps if needed, and finally testing it out.
