How are these beach and pool showers attached to the plumbing water supply lines?

" These beach and pool showers come with 1/2" x 12" stainless steel flex hose. They are connected by using standard 1/2" pipe. The water line should protrude about 1-1/2" out of the ground. Then it's simply a matter of connecting the two with a stainless steel braided hose. "If I order an ADA compliant pool shower that includes a foot shower, will the foot shower have the metered push-button valve, too?" The ADA compliant foot shower models come with push-button valves. at both main valve and at the foot shower valve. The hose bibbs and drinking fountains are push-valve or lever handle (ADA compliant).  more
