At LESSO America, we've seen Schedule 40 PVC pipe used in a wide variety of systems, from home plumbing to commercial construction. When customers ask us what Schedule 40 PVC pipe is used for, the short answer is: quite a lot. Its versatility, durability, and ease of installation make it a go-to material for engineers, contractors, and facility managers across North America.

Schedule 40 refers to the pipe's wall thickness, which is suitable for moderate pressure applications. Combined with the chemical resistance of PVC material, it offers a dependable option in environments where corrosion resistance and long-term performance matter.

Potable Water Lines in Residential and Light Commercial Systems

One of the most common applications for Schedule 40 PVC pipe is in potable water distribution. Its smooth interior surface allows for efficient water flow while resisting buildup from minerals and contaminants. That means fewer interruptions and a longer system lifespan.

We manufacture our Schedule 40 PVC pipe to meet ASTM standards, ensuring consistent quality and safety for use in cold water supply lines in homes, schools, and light commercial buildings. For above-ground applications, it can be glued using solvent cement, offering quick and secure installations without the need for heavy-duty tools.

Drainage and Venting Systems

Another key use of Schedule 40 PVC pipe is in drain, waste, and vent (DWV) systems. In both residential and commercial construction, it plays a crucial role in managing wastewater and venting sewer gases.

Because PVC is non-reactive and resistant to the harsh substances often found in wastewater, it performs reliably over time. The lightweight nature of Schedule 40 pipe also makes it easier to install in wall cavities and ceilings, which is ideal for multi-unit buildings or retrofits.

We offer a full range of compatible DWV fittings to support smooth transitions and turns, which helps prevent clogs and maintain proper flow and pressure within the system.

Pool and Irrigation Systems

Outside of buildings, Schedule 40 PVC pipe is frequently used in swimming pool plumbing and landscape irrigation systems. Its resistance to UV exposure, moisture, and soil conditions makes it well-suited for outdoor environments.

In pool systems, it's commonly used for circulating water between filters, pumps, and returns. In irrigation, it supports efficient water distribution to lawns, gardens, and agricultural plots. Customers appreciate that our Schedule 40 pipe is tough enough to handle these jobs without being unnecessarily bulky or difficult to work with.
