At LESSO America, we've seen firsthand how PVC plumbing fittings have become essential in both wastewater management and irrigation systems. Their durability, cost-efficiency, and ease of installation make them an excellent choice across a variety of environments. Whether it's handling high volumes of water in municipal wastewater systems or ensuring even water distribution in agricultural fields, PVC fittings provide a dependable solution.

Our product range includes SCH40 and SCH80 PVC fittings, DWV (Drain, Waste, and Vent) fittings, and SDR35 sewer fittings—all designed to meet the specific needs of these demanding applications.

Wastewater Systems: Strength and Chemical Resistance

Wastewater systems place unique demands on plumbing infrastructure. Corrosive waste, fluctuating flow rates, and long-term underground exposure all require fittings that are not only strong but resistant to chemicals and wear. That's why many wastewater professionals choose our DWV and SDR35 fittings.

We manufacture these fittings from high-quality PVC materials that withstand exposure to wastewater and harsh cleaning agents. Designed according to ASTM standards, they provide a secure, leak-resistant connection that can handle years of use without degradation.

Our SDR35 sewer fittings, in particular, are built for gravity flow systems, offering a balance of strength and flexibility ideal for municipal sewer lines and residential drainage applications.

Irrigation Systems: Lightweight and Reliable

In irrigation systems, flexibility and flow efficiency are key. Whether you're watering a backyard garden or managing water for a commercial agricultural operation, system performance depends on secure, consistent water delivery. Our SCH40 PVC fittings are widely used in irrigation systems due to their lightweight design and ease of installation.

From tees and elbows to couplings and adapters, our fittings allow for quick changes and easy expansions to your irrigation layout. The smooth interior surface of PVC helps reduce friction, maintaining steady flow while minimizing the risk of clogs.

For applications that require higher pressure handling—such as pump-driven drip irrigation systems—we offer SCH80 fittings, which are built with thicker walls and higher pressure ratings.

Designed for System Compatibility

At LESSO America, we understand that plumbing systems are rarely one-size-fits-all. That's why we provide a wide range of fitting types and sizes to suit your system layout. Whether you're repairing a section of sewer pipe or installing a new irrigation zone, you'll find the right component in our catalog.

All our fittings are designed for compatibility with standard PVC pipe dimensions and meet ASTM specifications, so you can be confident they'll perform properly in the field.
