Water heater tanks are pretty easy to ignore; they can last for years without requiring any major repairs. However, if you're looking to have them last even longer and save yourself hefty repair costs in future, then a bit of maintenance is necessary. Just because these tanks are designed to last doesn't mean that you shouldn't take good care of them. Besides, the maintenance they need is only done a few times a year. You'll boost their lifespan and still get the best service from these tanks. Here are some of the best ways to extend the life of your water heater.

Remove the old anode

The anode of the heater tanks is used to prevent any corrosion from taking place. It attracts corrosion elements in the water such as calcium and rusts in place of your tank, thereby protecting the tank. However, as time goes by, its effectiveness significantly declines. It's good to replace the anode well before it becomes fully corroded.

Check your owner's manual to know where the anode is located so that you can assess its condition. If you see a thick deposit layer on the anode, then you'll have to replace it. You could also drain several gallons of water to check for orange rusty water. That can also mean it's time to replace your anode. You can go for aluminium or magnesium anodes, and these can be easily found at your hardware store.

Inspect the T&P relief valve

This relief valve is responsible for maintaining recommended pressure levels in the tank. It keeps the tank from exploding when the temperatures and pressures exceed the standard. Simply lift the valve lever to check its condition. If it doesn't let any water out, then you're treading on dangerous grounds. Replace it immediately.

Remember to turn off the power and drain the tank before replacing the valve. The water is going to be scalding hot when draining, so be extra careful. You could also call a professional to help you out.

Insulate the heater and pipes

Insulating your system will prevent heat loss and increase its efficiency. You could even lower your thermostat temperatures and still get water that's just as hot. This would prevent your tank from overworking and boost its lifespan.

Go for foam pipe insulation and ensure that it matches the diameter of your piping. An insulating blanket or bubble wrap would do just fine for the tank. Seal the cuts securely with tape.
