Small sumbmersible pump adapter for standard pool hose

I have an inground pool I need to partially drain yearly for my winterization. For this I use a small submersible pump on which I attach a normal garden hose via an adapter sold with the pump (1in NPT thread to hose adapter).

Removing the adapter, I'm left with 1in NPT Threads on the pump. The new printed adapter is a female 1in NPT thread to friction-fit taper adapter for the standard pool suction hose, giving much more water flow than my standard 1/2 inch garden hose, reducing the pumping time drastically.
