I have a dedicated 20 amp breaker in the panel box to a large 4 person whirlpool tub in my bathhroom. I thought it would be great until I realized it puts out hundreds of gallons into my septic each time I use it. Therefore it sits pretty with no use over last 20 years…lol It works. … but not worth blowing my septic field. So , I am remodeling my hall bath and bought a single 5 foot whirlpool tub that's manageable with my septic. I tore out old tub and it has a common wall with my large whirlpool tub. So, I piggy backed into the single 20 amp line as I wont use both tubs at same time ever. The new electric socket works with regular plug and no problems. However, I figured electrical code probably calls for a GFCI socket since it's near water. So I sprung for a 20 amp GFCI socket and it trips when I plug anything in to test it. Wondering why it would trip and the regular socket works no problem?
Thanks,

You don't need another GFCI, just put a regular receptacle here
The breaker's a GFCI already (between the TEST button, and 680.71 requiring GFCI protection for the existing tub), so you don't need another GFCI device to add to the confusion. Simply put a regular 20A receptacle in with a "GFCI Protected" label on the faceplate, and you should be fine provided the GFCI breaker trips when you push its "TEST" button.
