When to replace

Same end-of-life indicators as the 50G — tank-shell rust streaks, persistent shell leaks (not valve leaks), gas-valve failures persisting after thermocouple/pilot replacement, popping/rumbling that flushing doesn't clear.

If the tank is leaking, replace. If valves only, repair makes economic sense through year 10.

Modern Rheem equivalents

Direct replacement: Rheem Performance Platinum 40G Gas — same atmospheric form factor, modern FVIR burner, 12-year warranty + EcoNet WiFi.

Contractor channel: Professional Classic Plus 40G (PROG40-38N-RH62) with 8-year warranty.

For closet installs without chimney access, see the modern Performance Power Vent 40G.
