Harold:
Ok, you met the 'guy' requiring a bond back to the panel?? Is he the same 'guy" requiring driven grd rods (2) at spa/hot-tubs (outside). Spa/HT being recirculating non-drained, chemically/ozone treated heat maintained water with/without air injection??
OK; IF there's a bond lug on the pump motor, a bond is required to all metalic piping, supply/drain, etc. If the plumbing is plastic, you have no where to bond. As to the 'spout'.....I would say IF it's 4" square (16 Sq Inches) I would request it to be bonded. NOTE I said REQUEST
Let the debate continue??
