1 Answer from this member: Unless you are very experienced on replacing water heater elements, Yes, I strongly recommend draining the tank first. Otherwise, it could cause a lot of damage. To drain the tank, be sure to turn the breaker and supply water valve off and open any hot water tap in the house.
You're spot on about draining your water heater. Very good Ible. Many years ago I had to replace my water heater. Where I bought the heater the technician told me besides draining the heater, replace the anode rod in the heater every 2 years, and in most cases you'll better than double the life of your heater. He told me he has the same water heater in his house for 23 years. I've been changing mine every 2 years.
