I am runnining a 2 in. shower drain. Question is this. Will it hurt to have two 90 degree bends in the drain line on a horizontal run of about 4 ft? The drain line will run from the shower trap with the two 90 degree elbows to a sanitary T. the drain then will run down a vertical wall. Will the elbows cause any flow problems? Thanks for info. Dave

Hi Dave, You can use (2) 90's in your 4' run, however I would use long sweep elbos in place of regular 90's. If you can't locate long sweep 90's you can use a 45 degree elbo and a 45 degree street elbo. The longer bends will insure better drainage with less chance of a clog. Good luck on your project. Tom

Tom, thanks for the prompt info. Its good to know you can get reliable tips and information somewhere. Im sure I will have more questions later. Thanks again Dave
