How to Replace an Electric Water Heater Heating Element · Step 2 of 10
In this video
Attach a garden hose to the drain valve at the bottom of the water heater tank. Route the other end of the hose to a suitable floor drain or a large bucket. Use a flathead screwdriver to turn the drain valve's screw counter-clockwise to open it. To help the water drain, go to a sink inside the house and open a hot water faucet; this will break the vacuum in the lines. Allow about a quarter of the tank's water to drain out, then close the drain valve by turning the screw clockwise.
Goal: Lower the water level in the tank below the anode rod to prevent spillage during removal.
- The water draining from the tank is hot and can cause burns. Handle the hose with care.

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.
