    Changing Filter on Sta-Rite S7D75

    Hello all,
    I found a few openings in the edges of two grids today while cleaning the filter. I was hoping for something less expensive but... Anyway I ordered the replacement set and started to remove the old one when I came to a stop at the pvc coupling that holds the manifold to the stand pipe. It will not turn... Either direction, and I do not want to break it. Does anyone know which way it should turn while looking down at the fitting? Any good ideas or suggestions on how to free it? I am soaking it now with PB Blaster in hopes it may free it up. I have had no luck with strap wrenches and have made some modifications to a oil filter wrench in hopes of better results. Any suggestions appreciated.

    Thanks!

    Is this what you are dealing with?


    What part are you struggling with? #10 looks like a union fitting, that I would guess unscrews CW when you are looking down on it.

    Yes, that is it. I agree with the presumed direction, but it has yet to budge. I am hoping to try it again tomorrow, assuming no more tornadoes for awhile... Thanks,

    Well, I guess the PB Blaster did the trick. You were right on the direction, I was concerned that it may have been a reverse thread. Thanks!
