    New CW Coil

    Swapped out a CW coil a few months ago.

    Thanks for posting. Why black iron, is that what the connections on the coil are made out of?

    Connections were 2.5" threaded reduced to 2". No real reason for the Iron fittings on the top connection. Was told to go pipe it and given a box of fittings and it just worked out.

    We have one up to 2" its looks so much better soldered. Not sure a would have been able to fit all those PP fittings in there and keep it plumb. I used a street male adapter also good luck finding one in stock thats PP.

    Face to face on a 2" PP fitting you are suppose to leave a 3/4" space.

    Nice clean work, but you should not connect black iron directly to copper. You could use a dielectric union to avoid the possible reaction from the different metals.

    Is it still a concern with a closed loop and chemical treatment? The coil manufactures use a steel header and copper passes on the coil.
