The opening is sealed by O-rings and a threaded open cap compressing the O-rings and the pool material against a collar on the threaded elbow. At the other end, the threaded elbow has a coupling and a hose adapter. The hose adapter has a controllable water flow on and off valve at one end and a fitting at the other end for removable attachment to a cooperative fitting on a garden hose.
