The plumbing designer quit and I am left holding the bag. I have avioded drawing isometric plumbing diagrams for years. Now I have to suddenly get good at it. I have trouble visualizing the whole thing. Is there somewhere that I can get the basics into my brain? Do not tell me to think of the building disappearing and leaving the pipes. That mess on the screen does not look like any plumbing I have ever seen. My toilet looks like a toilet not a dogs hind leg.
