Do you have to drain a water heater to replace the elements?
It isn’t necessary to remove the elements or drain the tank to test them, but the elements must be removed (and the tank drained) to replace them. To test the elements, you will need a voltage/OHM meter. Turn off the power to the heater first and disconnect the two wires to the elements.
Is it bad to change the thermostat on a water heater?
It’s also not a bad idea to change the thermostats (even if they test good,) if you are changing the elements. In every water heater, there is a plastic dip tube that brings cold water to the bottom of the tank to be heated and prevents it from mixing with the already heated water at the top of the tank.
Can a heating element be changed without draining the VAC?
I change all my elements without draining. You lose almost no water. However,keep a towel and shop vac close by. The only problem comes in when it is a old corroded element and the rubber gasket wants to stick in the hole. Other times,the element is busted and hangs up coming out.
How do you reset an electric water thermostat?
The thermostat is equipped with a thermal cut off switch. You will need to push the reset button to reset the thermostat after the problem has been corrected. Unplug the power cord to the water heater and remove the front cover. Press the reset button firmly with the tip of a ball point pin, extra small screwdriver or similar object.
