I connect my drain hose to a hose bib outside, with the other end laying on the deck. I run water until water comes out the other end. Then turn off the water, put the tank end in the tank, and turn on the water briefy until no more big air bubbles show up in the tank. Shut off the hose bib, unscrew the hose from it and poke it where I want the water to drain (into plantings). The hose is full of wate so the siphon is fully established. When enough water drains out, I screw the hose back on the hose bib, and turn on the water to fill the tank. When the tank is full I shut off the hose bib, pull the hose end out of the tank, and holding it high I carry it ourdoors. Disconnect the hose from the hose bib and roll up the hose as the water flow out of the hose.
