    Nautilus P4 fitting leaking

    When I went to de-winterize and pulled the pass thru wall off, I saw a spot of pink anti-freeze on the floor under the Nautilus tee connection behind the blue valve. Had no leaks last year at all. I could see the pink had run down from top of the fitting so it seemed like the fitting had loosened. Figured it would be a good idea to put a small tray and a water leak detector in it. Been hooked up for a week now and nothing. This morning I go out and sure enough tray has quite a bit of water in it and alarm is going off.

    I still haven't figured out how those fittings are tightened/sealed/loosened. I tried tightening the fitting, but it is tight. Looks like I have some disassembly ahead and any P4 repair guidance or links would be much appreciated.
    Thanks,
    John

    The manifold (blue valve portion) blew. Incredibly the local dealer had a replacement!
