I had to replace a leaking o-ring, replaced but now I cannot seem to get the strainer basket spun on and aligned upward, stops facing down every time, no matter where I begin spinning it back on. Does it remain "loose" and only held in place by retaining clip? Also, when I removed, I don't think I saw any teflon tape on the threads. Do I use it?
It's a Hayward SP1580X15 THANKS in advance.
