Returned and removed the old 50 gallon lowboy water heater and installed a new 50 gallon lowboy electric heater. Reconnected to existing water, electric, and t&p lines. Found a leak on the lower element from where a gasket pinched. Drained the tank back down and replaced the gasket. Tested all work to ensure proper functioning and no leaks. None were found. Waited for heater to produce hot water.
