Is it acceptable per code for me to have 1/2 inlet and outlet pipes on a water heater? Also, is it acceptable, albeit not smart to not have a floor drain in a room ion which the hot water tank is located? Theses are existing conditons of the home. Updating them would be difficult and costly. Thinking about making the water heater a tankless one.

Thanks!

More important then the connection size, is the fixtures being served with hot water. If the pipes serving the fixtures are properly sized, 1/2" is fine.
Floor drains are not required for me, but I do need to have the discharge from the pan and T&P piped individually to an approved receptacle or to the exterior.
