Most units will have a valve to drain the fresh water tank. Usually they are a 1/4 turn valve. You said a plug, are you meaning for the water heater? If so it's a 3/4" NPT (National Pipe Thread) nylon plug. Use nylon to prevent electrolysis problems between dissimilar metals.
Are you advocating using a nylon pug in both type of water heaters?
These are the only type I've ever seen.
