This exactly what happens. I use a sbig pump with a 20l drum of water. The tubing drapes from the camera over the finder scope mount( to stop any tension on the camera) back to the drum at the pier base.
I connect it up and turn it on. I have to lift the drum to establish flow but can then leave it on the ground and it will flow with no problems.
It works very well and gives me much better cooling than no water. I change the water about once a year.
I don't find it difficult to use at all.
