Does anyone know where to get a connector so I can hook up a hose to one of the drain holes in my Intex above ground pool. It has one on either side about 2 or 3 inches above the ground. It has a cap that threads over it on the outside and a plug the pushes in from the inside. The outside thread is bigger than a garden hose and I have no idea what type of connection it is. I'd like to attache a hose to it so I can drain the last 10-12 inches of water out. I was able to siphon most of it but not that last bit. Anyone got any ideas?
