Remove Sediment by Flushing the System

Sediment FilterSediment build-up in your water heater can cause numerous problems, the worst of which is a total malfunction that results in a flood. Sediment build-up results in a total hot water heater failure because it can cause corrosion to the tank. 

This is especially true in areas that have hard water. You may also have a water heater electrical failure, which can cause numerous other problems on its own, as well.

To avoid a total failure that results in a major leak, causing a house flood, it’s important to flush out your water heater annually. A local water company can also test your water and recommend if your water levels indicate a higher frequency of a total water heater flush.

Water Heater Danger Signs from Sediment Build-Up:

Insulate Your Water Heater Properly

When your water heater has more exterior protection from cold temperatures it is able to use less energy keeping the water temperature high. While this sounds appealing for maintaining a low energy bill, insulating your water heater improperly can be a safety hazard that results in a hot water heater failure and possibly other issues.

Always purchase an insulation kit or product specifically designed for hot water heaters. Talk with your local water company or plumber about insulation options and consult with them before completing the work yourself. While this may seem like a small and easy task it should be handled with care and the proper safety attention.

Check for Rust to Avoid a Flood

However, you don’t just check the exterior of the tank to check for rust and flooding problems. Instead, you want to check the anode rod in your water heater. This rod’s purpose is to rust away before your tank — once the rod is completely corroded, the tank is next.


Differing water levels affect how quickly this rod corrodes. Hard water or the use of a water softener can cause this to corrode in only a few years. Call in for a replacement rod before your tank’s warranty expires and work with your water company to check your water levels to see if you can extend the life of the rod, therefore, extending the life of your hot water heater.

Monitor Gas Water Heaters for Leaks

If you have a gas water heater, you’re at risk for carbon monoxide or other gas poisonings. This happens when the vent is functioning correctly, either due to a malfunction or an obstruction. 

Most of the time, you can’t discern whether or not your water heater is leaking gas simply by taking a visual look, which is why this hot water heater failure prevention will require a few extra tools.

Always make sure you have a CO detector in your home and ensure it is working properly. Test this regularly and always replace the unit immediately if the battery fails or falls into disrepair for another reason. An annual inspection from your water company is also another way to confirm there has been no internal failure, causing the vent to stop working properly.

Keep the Water Heater Area Clean

To prevent this, you want to ensure the area around your water heater is clear of any debris, clutter, or other flammable materials.

Gas water heaters can have minor leaks that can fuel a fire or electric units can have a small malfunction. To prevent against this disaster, check for and remove leaves, cobwebs, dust, cardboard, paper, or other items that may have gotten stacked around the unit. During your annual water equipment inspection have the water crew check your water heater and give it all the clear.

A temperature-pressure release valve mishap can occur due to a faulty connection, a weak spot in the connection, a valve that has gone bad, or other issues. What you want to do is check annually to make sure this fail-safe is still working properly. The local water company in your area can assist if you’re not sure how to check or if you’re cautious about testing.
