DWV elbows are usually long-radius ("sweep") types. To reduce flow resistance and solid deposits when the direction of flow is changed, they use a shallow curve with a large radius of curvature. In addition, a well-designed system will often use two 45° elbows instead of one 90° elbow (even a sweep 90° elbow) to reduce flow disruption as much as possible.
Central vacuum system inlet fittings are intentionally designed with a tighter radius of curvature than those of other bends in the system. If vacuumed debris becomes stuck it will jam at the inlet, where it is easy to find and remove.Clean-outs are fittings with removable elements, allowing access to drains without the removal of plumbing fixtures. They are used to allow an auger (or plumber's snake) to clean out a plugged drain. Since clean-out augers are limited in length, clean-outs should be placed in accessible locations at regular intervals throughout a drainage system (including outside the building). Minimum requirements are typically at the end of each branch in piping, just ahead of each water closet, at the base of each vertical stack and inside and outside the building in the main drain or sewer. Clean-outs usually have screw-on caps or screw-in plugs. They are also known as "rodding eyes", because of the eye-shaped cover plates often used on external versions.
