3 Tips on How to Remove Rust from Electric Water Heaters


Like any appliance, a water heater can break down over time. If it happens and you have a warranty then the company should fix it. However, if not then you should be aware of the parts and be able to troubleshoot any problems. You have to keep in mind that heaters are dangerous so make sure you know what you are doing. Always turn off the power supply and inlet water pipe and fixing the hose to the drainage valve. There are steps involved when you want to remove rust from your electric water heater.

Here we will cover some tips on removal.

-add insulation

-set the temperature

-flush the tank and check the anode rod

Taking care of your water heater will keep your home running smoothly. When you add insulation you can save on water heating costs by at least 9 percent. When you flush the tank you get rid of sediment and the tank will last longer. A good anode rod prevents the inside of the tank from rusting. The anode rod is the most important factor in the tank running well. In fact, some tanks can have more than one. Newer technologies can be used in the form of powered anodes that will take care of odors from bacteria. If the tank is full the electrolytic process starts and the anodes are destroyed to protect the naked steel. Powered anodes are electric and cannot be destroyed.

Cleaning your water heater is hard work and once you put cleaner in it has to be flushed out. A good CLR cleaner is best because it can clean the calcium, lime and rust. The electric heaters contain mineral deposits on the heating elements and then they fall to the bottom. Most will flush but some are too big to get through the drain valve.

Here are some prerequisites to remember:

Disconnect-turn off the electric power from the breaker box and mask the switch. Then disconnect the water inlet pipe.

Drain Some Water- Use a water hose and put it on the drain valve. Run it to a sink where the hot water can sit. Open the drain valve after you unscrew the water supply line. Let the all the water drain and then close the valve.

Put in the cleaner and check it by putting a plastic bag over the inlet pipe and watch if it inflates. When it does inflate the CLR cleaner is neutralized.
