I use a Mag 9.5 attached to 50 ft water hose to move water around my house. Getting water to go 20' ft up may be a problem though.
If you cut the end off a garden hose, it fits perfectly around 1.5" vinyl tubing. Only cut the end where the water exits because, you want the end that screws onto a bib or pump. I also made a PVC adapter that hangs on the tank that attaches to the hose so, the hose wont fly out of the tank when draining or filling. There is a ball valve on that to control water as well. It makes a world of difference when you have the right tools for the job.
