Oh yes, I DO know...I am a moron! First one went in too far because I was being proactive and moving it slightly to deal with wear patterns, second one was installed crooked, third one replaced #2 same time...then still got it in too far. Fourth time's a charm I hope. Putting this down on here reminded me that it was actually replaced 4 times, not 3. So I'm an even bigger moron than I had at first thought. I had hoped that as I got older I would learn my life lessons the first time. Sigh. The PVC cap really did work well as a seal setter...lined it up perfectly...a few taps with a hammer got it right where it was supposed to have gone in the first place.
