Can I replace a hot water heater with a direct swap if ports match?
Finding a new water heater with matching port and plug locations does not guarantee a simple, direct swap because tight spaces often complicate removal and installation. Obstacles like cramped clearances can require cutting tools to get old parts out, turning what seems like an easy swap into a more involved project.

“Just replaced what looks to be the original Magnesium anode rod on my hot water heater. This is on a 40gal gas Rheem that has been run on soft water. Had to take a reciprocating saw to it in order to remove it from the cramped space.”source ↗
“Should I have just left it in to finish off its life with the HW heater?”source ↗
“If I am putting in a new hot water heater and find one with all the plugs and ports in the same spots is it as easy as popping out the old one and putting the new one in?”source ↗
