I'm new here, just started trying to do the pool myself this year... Got my chemicals under control, but now the lock knob on the top of the filter just stripped and is stuck on my filter. The knob just turns around forever and the top of the filter case is just as stuck as if it were screwed in all the way.
I can't get the picture to upload, but it is a Blue Haven Pool 190 series cartridge, model C17502SBH. I tried searching the model number in google and came up with this http://edc.poolsupplyworld.com/wimag...-1.jpg?500x500 I am guessing Hayward may own Blue Haven Pools? Not exactly the same, but pretty close. The lock knob looks the same.
Anyone have any idea how to get the lock knob and the top of the filter off?
