Replace Lower Heating Element — Check for Leaks
Part of project
How to Replace an Electric Water Heater Heating Element · Step 9 of 10
In this video
To replace the faulty lower element without draining the tank, place a large absorbent towel directly below the element's access port. Using a water heater element wrench, engage the old element and use a screwdriver inserted through the wrench's holes for added leverage to break it loose. Have the new replacement element immediately at hand. Quickly unscrew the old element by hand, pull it out, and immediately insert and thread the new element into the port. Tighten it by hand as much as possible, then use the element wrench to secure it firmly. This 'air-lock' method minimizes water spillage to just a couple of gallons.
Goal: Swap Old Element with New Element
- Work quickly to minimize the amount of water that spills out. Having the new element ready to go is key.

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.
