Tips

• Opening the hot water side of a faucet will help it drain faster.
• If your element went bad due to age you should probably replace the Temperature and Pressure Relief valve as well.
• Sometimes tightening the element (turning it clockwise) a small amount could help loosen it for removal.
• The metal jacket on a hot water heater is deceptively sharp. Wearing leather gloves when removing the elements can prevent some nasty cuts.
• Sometimes it's possible to get a pipe wrench or pliers on the element instead of using the element wrench.
• You may want to write down what the pattern is from the old element to the new element. You don't want to mix the wires up.
• Turn the hot water on at a sink to bleed the air out of the line.

Warnings

• The metal jacket on a hot water heater is deceptively sharp.
• If you are unsure how to turn the power off or check if the power is off to the heater, consult a professional.
• Be sure you check the seat in the tank where the element gasket is going to seat. Be sure it is clean and free from any rust pits. Otherwise it will leak.
• DON'T FORGET THE WASHERS! The elements usually come with washers, if you replace them - remember to put the washer on the element.

Things You'll Need

• Screw Driver
• (Optional) Element Wrench
• Smaller water heaters (ie: 17 gal) may need a very small wrench.
