I am in process of selling my home. It has a 20 yr old water heater that
has seems to work just fine for me. There is no rust, no leaks, and the
temperature of the water is plenty hot when I need it.

The buyer's home inspector has just indicated that "water heater has slight
back draft and poor rate of rise" and buyer requests this to be repaired
prior to closing. What is he talking about? How significant is this?
(also costwise) Is it something worthwhile repairing, or should water
heater really be replaced?
