I have a in floor mounted urinal that is clogged and I cannot figure out how the plumbing is set up as I have just started a new job. I have used a power snake and am able to get her about 5 feet into the pipe but I cannot go any farther. If it were a wall mount I would know what to do. I just cannot figure this one out.
Before you do anything drastic call in a plumbing company that does alot drain cleaning, with the tools and experence they have, they might be able to save you. Or, just as the other guys have said; on the other web site it does not sound good!
