Thank you for your 1st response. After I read your reply I took my level to check the level of the horizontil pipe after the trap pipe. This was level. I then checked each pipe drain connection (3 of these) to the wall. The slope of the 1st connection after the horizontil pipe is away from the wall and toward the trap pipe (falls back toward the horizontil pipe). The next connection toward the wall is also sloped back toward the catch drain and horizontil pipe. The 3rd connection is also sloped toward the catch drain and the horizontil pipe. The slope keeps going “up” as far as I could measure it before the drain goes into the wall. Is the slope or fall supposed to rise in such a way? If you look at the connections you can actually see them slope “upwards”. Do I contact my contractor to have this replumbed or will I be laughed off?
Thanks in advance.
