I'm in the process of rebuilding an old hot tub. I've gotten to the point i'm ready to replace all the old Jets, suction cover, skimmer cover, etc.



This is the skimmer i have on the tub, but I only have the cover. There are 2 holes behind it in the fiberglass. What is the purpose of the piece that fits into that hole? Its almost like a hose is supposed to hook to it, but there is no place for it in my tub. Any ideas? Here is another version that has a 90 degree elbow back there that would fit in the hole...



I cant seem to figure out why they are there.......
