How to Replace an Electric Water Heater Heating Element · Step 8 of 10
In this video
With the new valve installed and in the closed position, turn the cold water supply back on to begin refilling the tank. Go to a faucet in the house and turn on the hot water side. Let it run until water flows out steadily, which indicates the tank is full and all air has been purged. Check the new drain valve for any signs of leaking. Once you confirm it is full and not leaking, you can reinstall the access panel and turn the electricity back on at the breaker.
Goal: Complete the installation and restore operation
- Do NOT restore power to the water heater until it is completely full of water. Powering an empty tank will instantly destroy the heating elements.

FAQs
What are the most critical safety steps I must take before replacing an electric water heater heating element?
Always start by turning off the power to your water heater at the circuit breaker and verifying it's off with a non-contact voltage tester. Next, shut off the cold water supply to the heater and drain the tank completely. Failing to do so can result in serious electrical shock or water damage.
Can I use a regular socket wrench to remove the heating element, or do I really need a specialized element wrench?
While a standard socket might fit, a specialized heating element wrench (like the Rheem PROTECH Dual Head Element Wrench listed) is highly recommended. It's designed for a snug fit, reducing the risk of stripping the element's hex head, which can make removal significantly more difficult.
The project is listed as 'beginner' and '4 hours' – is this realistic for someone with no plumbing experience?
Yes, it's beginner-friendly as long as you follow all safety procedures and instructions carefully. The 4-hour estimate accounts for the time-consuming process of fully draining and then refilling the water heater tank, along with potential delays like a stubborn element.
What's the most common mistake new DIYers make when replacing a heating element, and how can I prevent leaks?
A common mistake is not fully draining the tank or not properly seating the new element's O-ring/gasket. To prevent leaks, ensure the O-ring is perfectly positioned before tightening the new element firmly, but not excessively, and carefully monitor for drips after refilling.
