They are both right,however you should also check your water pressure in the house, it should not exceed 75psi, if it does have a pressure regulator installed on the main water line to the house. Also a small expansion tank should be installed on the cold water line going to the water heater. By installing the pressure regulator and expansion tank the water heater will not have to expand as it heats therefore saving the life of the water heater as well as the stress on the faucets, pipes,etc. in the domestic water system. Note: Your water heater expands approx. 1 gallon for every 40 gallons of water heated.
Good luck
