      Does it hurt the hot water tank if the hot water is coming out of the marking of the cold and vice versa? The cold water feed is going in where the hot is marked?
      Thanks

      Every water heater comes with a dip tube slipped inside of the cold water inlet to keep the cold water entering the tank down at the bottom of the tank. This way the colder water is heated and rises to the top of the tank. The way you have your tank hooked up, your colder water is mixing with with your aready hot water and you probably not going to get temperatures you want from you heater.

      You can run the cold water supply in the hot side if the dip tube has been changed from the orginal cold side to the hot side .If you do this you will have to use a close nipple installed in the hot side first and then insert the dip tube in the nipple .If you dont use the nipple the dip tube will fall into the heater

      The cold water supply can be piped into the hot side providing the dip tube is changed to the hot side.In order to do this a close nipple will have to be installed in the hot side first to prevent the tube from falling into the tank

      Short of taking the connection off or, if it’s an electric water heater, taking a heating element out, is there a way to tell which side the dip tube is on? Which is more work?

      If I had a choice,I would take the union loose on the tank.

      Open the relief valve and see how long it takes before you get cold water. If it is almost instantaneous or at least a very short time then the dip tube is on the wrong side.
