Good point about the skimmers... I forgot to mention that.

About the 1-1/2" directionals.... One of my customers made a mistake and stubbed 2" through the wall. I went on a search for a 2" fitting and could not find one. If any one knows if such a thing is out there, please let me know.

And please forgive all the typos in my posts. I'm using a lap top and those long fingernails.......
