90 degree sweep vs. two 45s

keve1212 · Feb 3, 2011

Hi All -

If I am making a horizontal 90 degree turn with a 3" toilet drain line, which is better, using two 45 degree turns or a single 90 degree sweep fitting? I would prefer to use the sweep, but don't want to do so if it's more likely to cause me problems down the road.

Thanks for your help!

I would use a long sweep 90 if I had the room.

A horizontal bend?
A 45 and a street 45 together make up a long sweep 90
Either way works about the same.

If it is the turn under the toilet, I always use a closet bend which has a very short/abrupt turn.
