Polypropylene is used extensively due to its unique blend of properties that make it ideal for a wide range of applications. As a type of plastic, it is remarkably lightweight yet exceedingly tough, making it suitable for items that require durability without added weight. Its resistance to many chemical solvents, bases, and acids contributes to its versatility in chemical containers and medical equipment. Polypropylene is also known for its high melting point, making it suitable for microwaveable food containers and dishwasher-safe items. Additionally, it does not absorb water, which is beneficial for outdoor and marine applications. Its recyclability further enhances its appeal as an environmentally friendlier option compared to other plastics.

Attaching PVC to cast iron pipe involves a few steps, ensuring a leak-proof connection. First, clean the end of the cast iron pipe; debris from cutting or corrosion should be removed. Use a no-hub coupling, which is specifically designed for this purpose. These couplings consist of a rubber sleeve and a stainless steel shield equipped with clamps. Slide the coupling over the end of the PVC pipe, then insert the end of the PVC pipe into the cast iron pipe. Slide the coupling so it spans the joint between the two pipes, ensuring an even distribution. Tighten the clamps on the coupling securely with a torque wrench, following manufacturer recommendations for torque settings. This creates a solid, leak-resistant seal between PVC and cast iron pipe, suitable for both drainage and vent applications in residential and commercial plumbing.
