1-1/2 Inch Schedule 40 PVC Pipe
Brand: Generic. Features include dimensions of 1.9″ OD and 1.61″ ID, a pressure rating of 330 PSI, and suitability for residential plumbing systems and standard pressure applications. This pipe is designed for drainage, pool and spa connections, and cold-water lines where rigid, durable piping is needed. The 1.9″ outer diameter provides compatibility with common fittings and sockets used in many home projects.
2-1/2 Inch Schedule 40 PVC Pipe
Brand: Generic. Dimensions show 2.875″ OD with 2.469″ ID and a 300 PSI pressure rating. This pipe is well-suited for larger drainage runs, pool and spa systems, and other high-flow applications in residential settings. It offers robust rigidity for long runs and easier installation with standard PVC fittings and connectors.
1 Inch Schedule 40 PVC Pipe
Brand: Generic. Features include dimensions of 1.315″ OD and 1.049″ ID with a 450 PSI rating. This size is ideal for smaller drainage runs, vent connections, or line runs where space is limited. The pipe offers reliable performance in residential plumbing and is compatible with common fittings for quick installations.
1-1/4 Inch Schedule 40 PVC Pipe
Brand: Generic. Dimensions are 1.66″ OD with 1.38″ ID and a 370 PSI rating. Suitable for general drainage lines, smaller plumbing projects, and setups where moderate flow is required. Like other Schedule 40 pipes, it is designed to withstand routine household pressure without sagging or cracking under normal conditions.
Pangda 6″ x 1′ Schedule 40 PVC Pipe
Brand: Pangda. Described as industrial-grade Schedule 40 PVC with a large 6″ diameter opening, designed for high-flow water passage and reduced clogging risk. The pipe is easy to install and can be cut to size for custom drainage configurations, making it suitable for irrigation, pool drainage, and outdoor drainage projects requiring larger diameter pipe.
Buying Guide: Key Purchase Considerations For PVC Pipe Water Drainage
Material and standard: Schedule 40 PVC is the standard choice for most drainage and plumbing projects due to its rigidity, chemical resistance, and compatibility with common fittings. Verify that the pipe is rated for drainage or cold-water use as appropriate for your system.
Size and compatibility: Measure the required diameter and wall thickness for your installation. Larger pipes offer higher flow capacity but require larger fittings and more space. Ensure the chosen pipe matches existing fittings or adapters in your system.
Pressure rating: Residential drainage typically does not rely on high pressure, but a higher PSI rating can indicate durability for certain applications or future expansion. Match the rating to your project’s expected pressure conditions and codes.
Length and customization: Some pipes are sold in one-foot or standard lengths and can be cut on-site to fit custom runs. Consider whether you need flexible or spliced options for long or irregular layouts.
Durability and environment: Outdoor or underground drainage may require UV resistance, corrosion protection for adjacent metals, and ability to withstand temperature fluctuations. Large-diameter pipes may be better for high-flow scenarios or future expansion.
Installation and accessories: Look for compatible fittings, couplings, clamps, and end caps. Some packages include clamps, rubber rings, or fittings that help simplify installation and reduce leakage risk.
Cost and availability: PVC pipe is widely available; however, larger-diameter or specialty pipes can be more expensive and may require lead times. Consider local codes and potential permit requirements before purchasing.
