Hello, I have an in ground gunite spa. One jet does not have as much pressure as all the others. I have removed the retainer ring and eyeball but can not get any further. How do I remove this inner piece? It has an octagon shape and text reading 1 1/4"x3/4". Also, is this setup missing the jet itself or is this an older design with eyeball and deep orifice inside the pipe? Any help is much appreciated. Thanks!
