Thank you Greg !

Thx! Your video was super helpful. Can also talk about sizing of the phalange thing that blocks water from coming through the top. Getting the right one 😅.

I have one of these installed, but water leaks through the top. Do you know why?

You probably have a bad seal. Is it newly installed or is it old ? The little rubber O ring needs to be in place to seal correctly.
