Is it spraying water around the nozzle? If not, I wouldn't worry about it.On the other hand, the old style nozzle with the grappling hook style reverse shoot, dragging through the water, would be scrubbing off your speed.See how the Place Diverter nozzle design has really been cleaned up to reduce drag (https://www.placediverter.com/home/product/place-diverter-nozzle).
