In this video
Using a pipe wrench, carefully grip the Temperature and Pressure (T&P) relief valve located on the upper side of the water heater tank. Turn it counter-clockwise to unscrew and remove it completely from the tank. Place some towels or a bucket underneath to catch any residual water.
Goal: Gain access to the inside of the tank
- Have absorbent towels ready to clean up any spilled water.

FAQs
What are the most critical safety steps to take before attempting to replace an electric water heater heating element?
Always start by completely shutting off power to the water heater at your electrical panel to prevent electrocution. Next, shut off the cold water supply valve to the water heater to prevent it from refilling. Be prepared for residual hot water when draining the tank, and wear appropriate protective gear like gloves and eye protection.
Is a specialized heating element wrench truly necessary, or can I use a standard adjustable wrench for this job?
While an adjustable wrench might work for some elements, a specialized heating element wrench (like the Rheem PROTECH Dual Head Element Wrench) is highly recommended. It provides a better grip, reduces the risk of stripping the element's hex head, and ensures you can apply sufficient torque for proper sealing without damaging the tank or element.
How long should I expect this project to take, and is it genuinely suitable for a beginner DIYer?
This project is rated 'beginner' and typically takes 1-3 hours, not including the full water heater drain and refill time. Most of the time is spent on draining and refilling the tank, while the actual element replacement steps are straightforward if you follow the instructions carefully and have the right tools.
What should I do if I notice a leak around the new heating element after refilling the tank?
If you observe a leak, immediately turn off the water supply to the heater and shut off its power at the breaker. The leak is likely due to an improperly seated gasket or insufficient tightening. Drain some water (below the element level), then carefully tighten the element further, or if needed, remove it, inspect the gasket, apply fresh pipe thread sealant, and reinstall before refilling and rechecking.
