Schedule 40 PVC pipe works best for low water pressure applications.
By contrast, Schedule 80 PVC is usually gray in color and has thicker walls; therefore, it can handle higher water pressures. Schedule 80 PVC is well suited for industrial and chemical applications.
First, pipe scheduling has nothing to do with the human concepts of time or schedules, rather, it is a defined measurement pattern. Scheduling is a fabrication plan used to specify a plumbing material's required total wall thickness depending on the full size of the pipe in terms of its width not its length. You can think of pipe schedule as a data table that has been pre-filled with textbook standardized values for pipes and fittings. Manufacturers seeking to produce 2" Schedule 40 PVC pipe will know exactly how thick at minimum the pipe walls must be to be classified as a 2"; Schedule 40 PVC pipe.
The exact wall thickness value requirements will differ on the specific pipe schedule intended and the plumbing's desired total width diameter. By definition, as pipe schedule values increase, e. This in turn indicates Schedule 80 pipe will always have thicker sidewalls when compared to Schedule 40 pipe, when used for a specified pipe size diameter and material. The increased wall thickness between schedules occurs as a reduction in the Inner Diameter measurement.
Pipe scheduling is used by contractors, construction and engineering firms as well as general plumbing handlers, installers and DIY do it yourself builders. In simpler words, pipe scheduling is used to determine the plumbing equipment that is right for the job.
In plumbing scenarios, it is important to compare and understand required pipe thickness, pressure ratings, chemical suitability and total costs, all of which are factors associated with and differ between pipe scheduling ratings. Rather, plumbing applications are extremely specific, especially those involving chemicals, and what is the best choice -- Schedule 40 or Schedule 80 -- will be an educated decision that considers the full variables of the pipe's intended use.
If Sch 40 is acceptably rated for the operational conditions of the scenario, one can save both piping material and associated costs by choosing to use Schedule 40 over Schedule 80 plumbing. The following property table overviews and compares Schedule 40 and Schedule 80 for its thickness, size, and maximum working pressure for fluids. So if you are building a low pressure sprinkler system and have some leftover Schedule 80 fittings from another project, you can safely use those.
If your household plumbing system was constructed from Schedule 80 PVC pipes, but never gets above a low pressure, you could potentially replace a damaged portion with Schedule 40 pipe. But for a professional job and optimal system function, it is always best to choose the correct schedule and use only pipes and components in that schedule. Both are extremely simple to install and use the same process depending on what purpose the piping system will serve. Every system will be a combination of pipes, fittings, valves, and accessories like pumps or tanks.
Some systems may also include hoses or require multiple pipe materials for main and branching lines. Sch 40 and Sch 80 PVC pipes are both lightweight and easy to cut to size with standard tools. From there you will use connector fittings to hold lengths of pipe together. The exact joining method depends on the project. The PVC solvent creates a strong and leak resistant seal between couplings, valves, and pipes. Threading can also be used with some systems to screw fittings, valves, and pipes together.
No matter the piping schedule you are using, the installation process for PVC pipe should be quick and straightforward without requiring special equipment or experience. If you are tackling your first PVC piping project or even if you have already completed dozens of projects, there are always questions when determining which pipe will help you complete a job safely, affordably, and with lasting results.

Every type of property: Residential Commercial Industrial Is likely to have different requirements, and uses, such as plumbing, landscaping, electricity, and more, all which affect both the type of pipe you need and its thickness.
In comparison to metal, clay, and even other thermoplastic pipes, PVC pipes are: Durable — Recent studies have proven PVC pipes can last upwards of 50 to years, resisting warping, cracking, and leaks during that time. They are also resistant to pitting and will not deteriorate when in contact with solid elements.
As a result, PVC pipes require less frequent repairs and have a lower risk of leaks or leaching fluids and chemicals into the surrounding High Capacity — PVC has a smooth bore interior surface. This means that any fluids that travel through PVC pipe are able to do so with less resistance and friction. It also means blockages are less likely to occur within the pipe.
Non Corrosive — PVC is non-reactive, meaning it will not deteriorate when in contact with most chemicals inside the pipe or minerals in the soil outside. Easy Installation — Because PVC is lightweight and the rigid plastic is simple to cut, installing PVC at any site does not require special tools or knowledge.
A hand saw or power saw is effective at cutting through PVC pipe and the installation requires only the correct fittings and PVC cement. Affordable — As a plastic, PVC is one of the most inexpensive piping materials for contractors. Because it is also long lasting and effective, it is also more cost effective for property owners. For PVC pipe, the manufactured schedules available are: Schedule 20 Pipe Schedule 30 Pipe Schedule 40 Pipe Schedule 80 Pipe Schedule Pipe Schedule Pipe While the pressure rating follows an upward trend as the schedule increases, the pressure at each schedule level decreases as the diameter increases.
Landscape Irrigation Schedule 40 PVC pipe is the preferred piping schedule for landscapers servicing residential and commercial properties. Pool and Spa Design Pool and spa builders generally use Schedule 40 PVC pipe for both above ground and in ground pools, spas, and hot tubs.
Buried or Concealed Electrical Conduit Unlike other projects that depend on fluid pressure to determine if Schedule 40 pipe is the right option, electrical conduit piping requires the correct physical strength. Potable Water Supply At residential properties and for some commercial applications, the water supply lines are lower pressure.
Between the higher pressure rating and better strength, applications that use Schedule 80 PVC pipe include: Commercial Plumbing General contractors, plumbers, and others working with commercial properties need piping solutions that are stronger than Schedule 40 pipe. Chemical Processing Manufacturing and industrial plants will often use Schedule 80 pipe for carrying, processing, or refining chemicals.
Manufacturing Schedule 80 PVC pipe can transport water, food and beverage products, and chemicals. Agriculture Larger scale agricultural properties often require higher pressure than landscaping irrigation to effectively move water throughout the property. Aquaculture For fish farming, fish hatcheries, and processing plants, many aquaculturists will use Schedule 80 PVC pipe.
Exposed Electrical Conduit When the placement of electrical wires results in the conduit being exposed, especially in an area where foot traffic or activity occurs regularly, Schedule 80 PVC conduit provides the additional strength needed to withstand a physical hit. Pressure Ratings for Schedule 40 and Schedule 80 PVC Pipe Because both the wall thickness and diameter are standards, this pressure rating is also a standard.
Schedule 80 piping has an increased pressure rating, but trades this off with: Reduced Capacity — The thicker wall of Sch 80 pipe adds material to the inside, not the outside of the pipe. This restricts flow capacity from what could be transported in a Sch 40 system at the same pressure.
At higher pressures, this reduced capacity is offset. But at lower pressures, the reduced capacity will have an effect on the system. To achieve the same interior capacity, a larger nominal Sch 80 pipe is necessary, which will take up more physical space. Heavier Weight — A thicker wall requires more material, and subsequently a heavier pipe. The exact increase in weight per foot of pipe increases as the nominal size does. At smaller diameters, the weight increase is a few hundredths of a pound while being about 5 pounds for the largest PVC pipe diameters.
This weight can make pipe more difficult to install and require additional manpower or support. Higher Cost — The additional material also means a higher manufacturing cost. Again, this may be a negligible amount for a small order, but will make larger piping projects far more expensive. The cost savings is the deciding factor for many people when choosing between Schedule 40 and Schedule 80 when the lower pressure rating is enough. Using pipes and fittings of two different schedules is not recommended because: A single Sch 40 pipe segment or fitting reduces the entire system to the Sch 40 pressure rating, even if the rest of the layout is constructed from Sch 80 Using Sch 80 pipes or fittings in a predominantly Sch 40 system is an unnecessary expense, so most people choose not to Different IDs and pressure ratings between Sch 40 and Sch 80 pipes can lead to an uneven water flow So if you are building a low pressure sprinkler system and have some leftover Schedule 80 fittings from another project, you can safely use those.
