Re: waterheater elements
It really doesn't affect the amount of hot water --- it was the dip tube that was mentioned ---- not the anode rod.

Undo the cold water inlet and pipe nipple and remove dip tube. Check condition and replace if required.
Modern electric heaters are wired for "non-simultaneous operation". What this means is that when filled with cold water the upper element comes on first. Once the upper part of the tank is hot power is switched to the lower element which heats the majority of the water.
The purpose of the upper element is to provide quicker hot water and perhaps to give a little redundancy so that one doesn't completely run out of hot water should the lower element fail.
When the top of the tank is hot the upper thermostat removes power from the upper heating element and transfers the power to the lower thermostat and heating element. If the lower thermostat is defective, then the lower portion of the tank will not be heated and the supply will be greatly reduced.
Check for power at the upper thermostat terminals where the power is sent to the lower thermostat and heating element. If there is no power then the upper thermostat should be replaced.
If there is power then check for power at the lower heating element. If there is no power at the lower heating element then replace the lower thermostat.
If there is power to the lower heating element then it should be getting hot. If it is not, replace it.
