I installed new heating elements in my 12yo AO Smith 40 gal. water heater today. I got the elements at Home D. The elements I removed were: top, 3500w 208v shorter; bottom, 4500w 240v, longer. The new elements were both the same length and both 4500w, 240v.
Quest. 1: Is it okay that I installed 2 of the same type elements?
Quest 2: Is it okay that the new element I installed in the top differs in watts and voltage than the element removed?
Quest 3: When I put a multimeter on the two screws that connect the power wires to the element in the top, the meter registers 240v. When I touch the probes of the meter to the screws on the bottom element, nothing. If I touch the meter probes to one of the screws connecting power to the bottom element and touch the other probe to the tank, I get 115v reading on the meter. Is everything okay here? Why no 240 at the screws on the bottom element? Why no reading at all at the bottom element when I touch the probes to both screws?
Quest. 4: do I need to do anything to the expansion tank on top after I've drained and refilled the water from the water heater tank?
Thx in advance for any help
