in THE MAIN WALL
Mineral's in the water, heat is seperating them and collecting in the bottom of the water tank? This would be my guess to start...:)

I'd have guessed anode rod but if it's old it's probably gone already...

    air in the domestic hot water pipes

    I have a client with air in her domestic hot water lines. When the hot is first turned on it spurts out air. Where is this coming from? It is a private well system with an old electric hot water heater. Any ideas or help willbe greatly apppreciated.

    It could be that your incoming water supply has a lot of air in it. When the water is heated the air comes out of solution and builds up at all the high spots in the system. That's why it only effects the hot water supply.

    What do you do about it? I have no idea. sorry

    hmm

    Didn't know that, with that little bit of info I would be checking my incoming piping (well to house) to see if there is a vacuum leak in it. Like Paul mentioned this could be pulling small amount's of air in to the house and trapping at the high point in the tank.

    Then again, if the tank was in prior to the installation of the water softener it could still be mineral's in the bottom of the tank breaking loose.
