Aloha again, sorry about the cap lock on, and the word motor in my first reply. the word should have been mortar mix. I belive you knew what i ment. I've seen alot of strange plumbing configurations in 30 plus years and there are sure more to come. Have you guys ever seen DWV out of BAMBOO? If you haven't then you haven't true plumbing before cast iron and galvi.
