Put new oring on my hayward filter top, works perfect no more leaks. I have a hayward c800 filter that kept leaking water out the top,I think maybe pool man dropped oring when he was cleaning the filter,its the oring that goes on very top where you screw down the handle, if its missing it will keep leaking water.
