When it comes to building reliable plumbing systems, durability is more than a feature—it's a necessity. At LESSO America, we focus on providing PVC pipe and fittings that are engineered for long-term performance, backed by quality manufacturing and consistent compliance with industry standards. Whether you're working on residential drainage, commercial water supply, or industrial piping, our SCH40, SCH80, and DWV product lines offer trusted solutions that are built to last.

Why Durability Matters in Plumbing Systems

Plumbing systems face daily wear and pressure—from water flow and temperature changes to environmental stress and chemical exposure. Poor-quality materials can lead to premature failures, costly repairs, or inefficient performance over time.

That's why we craft our PVC pipe and fittings using high-grade materials and advanced production techniques. Each product is manufactured with precision to ensure proper fit, easy installation, and dependable operation under a range of conditions.

Strength and Versatility with SCH40 and SCH80

Our SCH40 PVC fittings are a go-to solution for a wide range of residential and light commercial applications. They're pressure-rated and corrosion-resistant, ideal for cold-water lines, irrigation systems, and general plumbing. Their lighter weight also allows for quicker and easier installation without compromising durability.

For systems requiring added strength and higher pressure tolerance, we offer SCH80 PVC pipe and fittings. With thicker walls and robust construction, these components perform well in demanding environments, such as industrial settings and water treatment facilities. The extra strength of SCH80 fittings helps extend system life, especially where consistent pressure or impact resistance is required.

Dependable Drainage with DWV Fittings

In addition to pressure-rated systems, drainage applications need reliable fittings that support smooth water flow and long-term structural integrity. Our DWV (Drain, Waste, and Vent) fittings are crafted for gravity-fed systems and are widely used in both residential and commercial buildings.

LESSO America's DWV fittings are precision-molded to support easy drainage and venting, helping prevent clogging, backflow, and other common issues. Whether it's a simple elbow or a multi-branch fitting, each product is designed to integrate seamlessly with standard pipe systems and support code-compliant installations.

Built to ASTM Standards and Certified for Peace of Mind

All LESSO America products—including SCH40, SCH80, and DWV options—are manufactured to meet or exceed ASTM standards. We're proud to offer fittings that carry certifications such as cNSFus and cUPC, ensuring they meet strict guidelines for safety, quality, and performance.

These certifications reflect our ongoing commitment to producing pipe and fitting systems that offer not only strength and function, but also long-term reliability for a wide range of applications.

Conclusion

At LESSO America, we understand that every connection in a plumbing system matters. That's why we offer PVC pipe and fittings designed for consistent performance, structural durability, and easy installation. Whether you need the versatility of SCH40, the strength of SCH80, or the reliability of DWV fittings, our product lines are ready to support your goals.
