So we just moved into this house which has a waterfall feature. Question...there are two pvc pipes sticking up above the water line and the water shoots up, lands in the small waterfall pool, and then it falls down over the ledge into the main pool. Is that the way it is supposed to be? It looks kind of cheesy just two white pvc pipes sticking up like that. Is there supposed to be some kind of fixture or something over them? I have not seen anything online and nobody I asked so far has any answers. I have attached a photo...thx.
