There is this water supply line sticking out of the concrete apron near the shallow end of the inground pool. It looks like something screwed onto the top of it at one time. It feeds back to the basement of the house. When I turn the valve on water comes out of this but given its location I'm not sure what this is used for. Any ideas?
