Bellevue has always required that any waterless urinal has to first be approved by filling out an Alternative Methods form citing appendix L. Bellevue plumbing inspectors also required that a properly sized water line be ran and capped in the wall at the urinal "just in case, cause we know you're going to want to take them out". Bellevue Community College fought tooth and nail to get them approved and the plumbing inpsectors fought tooth and nail NOT to get them approved. The inspectors lost the politics but wouldn't you know....they have now removed them citing sanitary issues and too much maintenance. I hear that they want to add language to the 2009 UPC that says if a waterless urinal is used under apendix L, then a water line would have to be installed behind the wall. Don't know if it will make it in but I'll keep you posted.
