We have provided a video and of how Fixed Paramount PCC pop up heads are adjusted. Rotating nozzles are for the entire pool/spa. The fixed nozzles are designed to go at the bottom of the pool near the drain and constantly divert the water towards the drains of the pool. This causes the debris sent from the other pop up heads to shoot toward the drains.
This design mostly requires a separate pump to constantly push water through the 2 pop ups at the bottom of the pool to the drain. We highly recommend using a Variable Speed Pump, SOLD HERE, to maximize energy savings.
