I have an above ground Intex pool. I am having trouble with the 2 things that install thru the pool and connect to the pump. I don't know the proper name.

I think I have them hooked up wrong as when I place my hand over them nothing pushing out of them like last year. Yes the pump is fine. I think I installed them the wrong way. I will have to drain the freekin pool a lot to fix this now. How can I tell which one goes on what side? As I face the pool which one goes in left and which in the right hole?

Thanks.
