Welcome to our forum.
One thing many folks overlook in special installations such as yours is electrical bonding. Any metal objects in the near area of the tub must be connected together with what looks and acts like a ground wire. This means a wire needs to go to such things as handrails, light posts, planters, metal caps on top of walls, rain gutters and spouts, anyting metal in the area of the tub. This is very important, but more so if you will be running the tub w/out GFI protection for a short period of time.Be careful up there !
Dude,Great story! Wonderful veiw! As far as the girls go, well I guess thats just another benifit of spa ownership I doubt that would work as well in the states.
