When choosing a drain cleaner for PVC pipes, it's crucial to avoid chemical solutions that can damage or weaken the pipe material. Enzymatic drain cleaners are generally the safest option for PVC pipes. These types of cleaners use natural bacteria or enzymes to break down organic material causing the blockage in the drain, such as hair, grease, or food particles, without the corrosive effects of chemicals. Brands like Bio-Clean and Green Gobbler offer effective enzymatic solutions that are safe for regular use in homes with PVC piping systems. It's important to follow the manufacturer's directions for use and give the product sufficient time to work, often overnight, for the best results.
The number of monomeric units in polymer macromolecules varies widely, depending on the type of polymer and its molecular weight. Small polymers might have a few dozen monomers, while large, high-molecular-weight polymers can have thousands. Generally, synthetic polymers like polystyrene or polyethylene can be designed to have a specific number of monomers, whereas natural polymers like DNA or proteins have a naturally predetermined length dictated by their biological functions. The variation in monomer units is what gives polymers their vast range of physical and chemical properties, catering to uses from simple packaging materials to complex biological systems.

The cost of PVC pipe can vary significantly depending on several factors including diameter, thickness (schedule), length, and the retailer. Generally, smaller diameter pipes (1/2 inch) might start as low as $2-$5 for a 10-foot length, while larger diameters (4 inches) can cost $20 or more per 10-foot length. The schedule, or thickness, also plays a crucial role; Schedule 40 pipes are on the less expensive side, while Schedule 80 pipes, being thicker and more durable, cost more. Prices also fluctuate based on market demand, location, and whether you are purchasing in bulk. In addition to raw cost, consider the application (e.g., water supply, drainage, irrigation) which dictates the type of PVC (e.g., uPVC, cPVC) you'll need. It's advisable to compare prices across different hardware stores or online retailers and consider buying in bulk for larger projects to potentially save money.
