Check for physical damage to the tank, particularly rust and corrosion on the bottom of the tank. Check for water
marks on the floor of the tank. Check for a leaking TPR valve and discharge pipe is installed. The covers at the
electric heating elements should not be disturbed. Corrosion can be found where the water pipes are connected to the
top of the tank. The electricity or the fuel may be shut off. There could be scorching at the burner cover area. The
heat rollout shield should be in place. The draft hood and vent connector are often loosely attached. All tanks
should be accessible with at least 24 inches of working space around them.
Check the burner and flame. A damaged baffle (turbulator) could fall down on the burner.
