Replace Faulty Element — Refill the Tank and Check for Leaks

How to Replace an Electric Water Heater Heating Element · Step 6 of 7
In this video
To replace the faulty element without draining the tank, first turn off the cold water inlet valve to the heater. Open a nearby hot water faucet to relieve the system pressure, then close it to create a vacuum. Place a towel underneath the element to catch water. Using an element wrench or a 1.5-inch socket with a breaker bar, quickly unscrew the old element. Water will spill out. Immediately insert the new element and hand-tighten it to stop the flow. Then, use the wrench to tighten it securely, but do not overtighten.
Goal: Replace Water Heater Element
- A 1/2-inch drive breaker bar and 1.5-inch socket provide much better leverage for removing a stubborn, old element than a standard element wrench.
- Water inside the tank may be hot. Be prepared for hot water spillage when removing the old element.

FAQs
What are the most critical safety precautions I must take when replacing a water heater heating element?
The most critical step is ensuring the power to the water heater is completely OFF at your home's main electrical panel or breaker box before touching any wires. Also, turn off the cold water supply valve to the heater. Safely draining the tank of hot water is also essential to prevent burns.
Is a special tool required for removing the heating element, or can I use a standard wrench?
While some might attempt it with a large socket or pipe wrench, a specialized heating element wrench (like the 'Rheem PROTECH Dual Head Element Wrench' mentioned) is highly recommended. This tool is designed to fit the element's hex head perfectly, minimizing the risk of stripping it and making removal and tightening much easier.
How long should I expect this project to take, especially considering the draining process?
The estimated time for this project is 3 hours, but beginners should budget closer to 4 hours. Draining the water heater tank can take anywhere from 30 minutes to over an hour, depending on your tank's size and the drainage rate. Don't rush the process, especially during safety-critical steps.
What's a common mistake beginners make during installation, and how can I prevent leaks around the new element?
A common mistake is not properly seating the new heating element's gasket or not tightening the element sufficiently. To prevent leaks, ensure the new gasket is clean and properly aligned on the element before insertion. Tighten the element firmly with your specialized wrench, but avoid over-tightening which can damage the tank or element.
