No picture, but I'll describe the outcome. We couldn't remove the broken, plastic, bulkhead fitting because the two plastic nibs, part of the plastic water tank, would not allow any turn and screw out of the fitting using a 13/16" open end or socket wrench. Ultimately, we carefully, but nervously sliced off the the nibs with a razor blade. Then the fitting was easily unscrewed and replaced with the same ½ NPS male/barbed male plastic fitting from Lowes using both teflon tape and pipe joint compound to which we crimped a short PEX tube finished with a plastic ball valve. No more nibs to keep the fitting from unscrewing itself, but we do expect that was over-engineering and that the fitting will stay in place. One day latter and no more leaking water.
