If the main water valve is cut off should the water heater be cut off too?

I have a problem in one of my bathrooms where water is streaming from the bathtub faucet. I have a plumber coming the next day. Meanwhile, so I don't continue to waste water I've turned it off. My concern now is whether or not the water heater needs to be shut off as well.

Turn the water heater to vacation---or pilot---if you do turn it off remember to have the plumber relight it for you.

It is a good idea to turn the water heater heat off (turn gas heater control to Pilot) whenever the water supply is shut off. Have a hot faucet running water before turning the heat back on.

This prevents damage to the heater if for some reason the tank should empty out. Electric water heater elements can be damaged if the tank is only partly emptied.
When cleaning anything including baby diapers, it is better to sweep off or scrape off as much solid and semisolid material as you can first. (1) Less cleaning fluid or detergent needs to be used, (2) Less of a mushy mess which in turn means that bleaches or disinfectants will be more effective.
