PVC–U and C-PVC are widely used for pipes and fittings for the evacuation of waste water without pressure inside buildings (generally vertical). These are usually of medium diameters (< 160 mm). They can be made of compact PVC or have structured walls with a foam core. PVC soil and waste pipes are very durable, cost-effective and can be 100% recycled several times.
