I have a urnial that drains very slow and stops draining. The trap is clear so I pulled it off the wall and ran about 20-30 feet of rod in the pipe. The urnial right next to it runs great and I would think that they would be on the same line. The pipe in the wall runs in the direction of the other urnial. What is strange is that it plugs as soon as I run water in it and I know the pipe is clear because of the amount of rod I ran. Could it be the pitch on the drain is off? Thanks
Larry.
