These siphon systems are supposed to have a design that prevents back
flow. But I don't like to send anything through the garden hose that
is not potable water.

How about filling a garbage can with water and fish emulsion or such,
maybe elevated on some blocks, and using a dedicated hose plus gravity
to siphon the liquid out of the garbage can onto the yard?
