re: drain fitting
- I am sorry I did not make myself clear; I was hoping that owners of Urchin skimmers would answer me. Is there no-one on this list with an AquaC Urchin?
Anyway, the drain fitting is made into the collection cup at the top of the skimmer: http://www.google.com/images?hl=en&client=safari&rls=en&q=urchin+skimmer+drain+fitting+photos&um=1&ie=UTF-8&source=univ&ei=UEsfTZuiO8P48AbFk6icDg&sa=X&oi=image_result_group&ct=title&resnum=1&ved=0CCkQsAQwAA&biw=1076&bih=889
If this extra-long link does not work, I got the picture by googling "urchin skimmer drain fitting photos".
You can get the skimmer with or without the hole and drain fitting (presumably in case of overflow). Just want to know if this fitting has proved useful, necessary or not.
