I just recently tried to put a new shower drain line in my bathroom. The bathroom is completely gutted, and needed all new plumbing. I used a three piece shower drain (a tile shower will be going in) and 2" PVC. The Drain ran down about five inches into the trap then over about 11'' and 90 degrees down about 9" then over another 90 degrees about 9'' then a 90 degree joint hooked into the waste drain. I had a plumber come to my house and describe how to hook the drain up. I followed the directions despite my better judgement, and now it does not drain. Should I put the trap further below the drain? Should I put the horizontal pieces and more of a slope, and should I use 45 degree connectors instead of 90?

Your plumber advised you to install a illegal "S" trap and a dog leg in the drain line? No wonder you're having a drainage problem. You say you're tying into a "waste drain" would that be the toilet main or the lavatory branch? Because if you have connected to the toilet main that's another code violation. 45's and sweeps are always better for drainage then 90's and 1/4" slope to the foot is plenty. This line needs to be straightened out, the " slope to the foot is plenty. This line needs to be straightened out, the " trap and sharp bends removed and a proper vent installed. Good luck, Tom

The S trap was my fault. The plumber told be to instal a trap under the drain and told me that it was shaped like a u. So I went to home depot and said"I need a u shaped trap" and that is what I installed. As far as the rest of it, yes, that is what I was told to do. The plumber is a friend of my Dad's, and I was afraid from the beginning that he was just saying what would be easy, not necissarily right. Last night I removed my first work, and tried again. The line is tied into the vent now, I now only have two horizontal lines, they are both sloped, and connected with 45 degree angles. However, I still have the same trap installed, only it is not directly below the drain now. Is this still illegal? I ran water through the lines last night, it drained fine. I have not "glued" them together yet, I thought I would wait on a little more advice. Thanks for all the help.

General rule of thumb applicable to most of the adopted codes in the US:

You are allowed only one 90 degree change of direction on a trap-arm.
