My engineer called for an 8” spa beam and it is raised 6”. I realize it really isn't possible to put all the plumbing within the spa wall. So I am looking to use the waterway mini gunite jets 210-3400. I dont know if I should try to bring the 1.5” airline into the spa beam just to do a hartford loop, or if not, if I ran the line 4’ from the spa wall and did one hidden in the landscape if that would work? Only thing with doing it in the landscape is that I will have to run the airline farther down in the ground to go under what will be my screen cage footer. Any suggestions or tips? - thanks
