Place your hand in the water and feel around the return jet to see which direction the water is flowing. Turn off the filter.
Grab the eye of the return jet and adjust it so that the opening is facing away from the pool skimmer and parallel to the water surface. The return jet works on a pivoting swivel base. The easiest way to turn it is to place your finger inside the hole and direct it from there.
Turn the filter on. Observe the water flow and make small adjustments if necessary. The main thing to ensure is that the water flows away from the skimmer.
