    I ran into a waterlogged expansion tank that has a inlet pipe and a outlet pipe. this is mounted horizontally with the tank on the supply side of the system . hot water comes in on one side and exits on the other. anyone have a idea on the proper way to set up this tank. it does have a bleeder fitting about 2 inches above the pipe level but no way to shut off the water supply and no drain on the bottom.

    Thank you. gpost

    How do the two pipes connect into the system piping? Are there any "airtrol" style fittings (maybe made by Thrush?) where the tank connects to the system?

    It might be simple, and I hate to yank something out because it isn't understood.

    I'll research it a little, through some of my resources. Describe the connections as best as you can.
