We have an electric 40 gal. hot water tank in our garage and I believe something could be wrong with it. In the mornings, the water temp. seems a lot cooler than usual. This has been going on for quite a while and is not due to the colder water in the winter. We have two elements: 2500 watts upper and 2000 watts lower. Total says 2500 so I assume only one heat element is active at a time.
I want to check the thermostats and heater elements but don't know the correct procedure. If I need to change either one, MUST the water be drained from the tank first???? I don't want to unscrew anything and find water all over the place.
Thanks all for any information that you may offer.
