1
Assess and size the replacement
Review the existing tank, household demand, access, fuel or electrical requirements, water connections, venting needs for gas models, expansion control, and permit considerations to establish a suitable installation scope.
2
Remove and install the tank
Safely isolate and remove the old unit, position the selected tank, and complete code-compliant water, fuel, electrical, discharge, drainage, expansion-control, and gas-venting connections as applicable.
3
Test and plan for reliable use
Fill and start the system appropriately, check connections and operation, perform startup testing, address observed issues, and explain any remaining permit, inspection, or replacement-planning considerations.
