So we just bought a used hydrospa sarasota (looks like an old model) and everything works fine, but the bubbles you get in every hot tub wasnt appearing, and the air controller which you turn left/right was making no difference when turned, to find out theres a long rubber tube coiled up undernearth not connected to anything, when i blew in the tube bubbles started to appear in the hot tub, where does this tube connect to? Would love an answer!
