Common Everyday Usage & Benefits of 3″ x 20′ PVC Pipe
Where and How 3″ PVC Pipe Is Used
- Residential Plumbing: For sewer, drainage, and vent systems; commonly used to route waste water away from bathrooms and kitchens.
- Irrigation Line: Perfect for main pipelines in landscaping or agricultural irrigation systems.
- Commercial and Industrial: Used for chemical transfer (when Schedule 80 or CPVC), venting, or waste lines.
- Stormwater Management: Assists in channeling rainwater away from structures.
- DIY Projects: Frameworks for greenhouse supports, outdoor furniture, and storage solutions.
Key Benefits
- Corrosion Resistant: Unlike metal pipes, PVC doesn’t rust or scale.
- Lightweight and Easy to Handle: A 20 ft section of 3″ pipe is manageable compared to metal alternatives, making transport and installation simpler.
- Smooth Interior: Reduces friction, supporting strong flow for drainage or fluid transport.
- Affordable: Typically more cost-effective than metal or specialty piping.
- Versatile Connections: Compatible with a wide variety of fittings and couplings for branching and joining.
How to Choose the Right 3″ x 20′ PVC Pipe
1. Identify the Application
- DWV (Drain, Waste, Vent): For unpressurized sewage or drainage—choose Schedule 40 DWV.
- Pressurized Water: For irrigation or potable water under pressure—ensure pipe is rated for pressure (Schedule 40 Pressure or Schedule 80).
- Industrial or Chemical Use: Use Schedule 80 or CPVC for high-pressure or chemical applications.
- DIY/Non-Plumbing Projects: Light-duty DWV or foam core pipes suffice for structures and creative builds.
2. Decide on End Type
- Plain End: Good for simple solvent/glue/connector fittings.
- Bell End: One end is flared for faster “push fit” installation—common in long runs to minimize couplings.
3. Check Wall Schedule & Pressure Rating
- Schedule 40: Standard thickness for most home drainage and irrigation needs (up to 260 psi for some brands).
- Schedule 80: For settings demanding greater strength or pressure resistance (up to 400 psi).
- Foam Core: A specially engineered, lightweight variant of Schedule 40 for easier handling (use for non-pressure lines only).
4. Consider Local Codes & Requirements
- Plumbing codes may specify minimum pipe type and rating.
- Some codes require specific grades for potable water, chemical, or waste handling.
5. Compare Prices and Availability
- Buy from reputable suppliers—ensure pipes are in stock and check logistics for 20 ft lengths (may require special transport).
Practical Tips & Best Practices for Choosing and Using 3″ x 20′ PVC Pipe
Buying Tips
- Buy all pipe and fittings from the same manufacturer or ensure cross-brand compatibility.
- Account for delivery: 20-foot lengths may need a truck or special delivery arrangements.
- For large jobs, request volume discounts or contractor pricing.
Installation Advice
- Storage: Store long lengths on level ground and out of direct sunlight to prevent warping.
- Cutting: Use fine-toothed saws for clean, square cuts. De-burr inside and outside edges for proper sealing.
- Joining: Clean ends before gluing. Use proper primer and solvent cement for strong, leak-proof joints.
- Support: Support every 4–6 feet horizontally and 10 feet vertically.
- Pressure Testing: For pressure applications, always test the system before covering or backfilling.
Maintenance
- Periodically inspect exposed pipe for UV wear if outdoors for long periods.
- Avoid dropping or throwing pipes to prevent cracking.
- For buried runs, ensure proper bedding and cover to avoid stress points.

FAQ
- What is the difference between Schedule 40 and Schedule 80 PVC pipe?
Schedule 40 has a thinner wall and lower pressure rating, making it suitable for most residential drainage and irrigation tasks. Schedule 80 has a thicker wall, higher pressure rating, and is designed for industrial or high-pressure applications.
- Can 3″ Schedule 40 PVC pipe be used for potable (drinking) water?
Yes, as long as it is labeled and certified for potable water use. Confirm with local codes and buy pipes made specifically for drinking water if required.
- What are the actual inside and outside diameters of a 3″ PVC pipe?
A 3″ Schedule 40 PVC pipe typically has an outside diameter of 3.5″ and an inside diameter of about 3.068″.
- How much does a 20-foot length of 3″ PVC pipe weigh?
A standard Schedule 40 3″ PVC pipe in 20-foot length weighs around 19–21 pounds. Foam core pipes can weigh less, while Schedule 80 varieties are heavier.
- How do I transport 20-foot PVC pipes?
Due to their length, transporting a 20-foot pipe typically requires a pickup truck, trailer, or delivery service. Some suppliers offer job-site delivery for large orders.
- Are all 3″ PVC pipes rated for the same pressure?
No. Pressure ratings vary by type. Schedule 40 handles up to 260 psi (for pressure-rated varieties), while Schedule 80 supports up to 400 psi. DWV types are for non-pressurized use only.
- Is primer required before gluing PVC pipes and fittings?
Yes, you should always use a PVC primer before applying solvent cement to ensure a strong, leak-proof bond.
- What’s the difference between plain end and bell end pipe?
Plain end pipes have straight ends for joining with couplings, while bell end pipes have one flared side for direct connection to another pipe, reducing the need for extra fittings.
- Can 3″ PVC pipe be buried underground?
Absolutely. It is commonly used for underground drainage and sewer lines. Be sure to follow proper bedding, backfilling procedures, and local codes for burial depth and protection.
- What is “foam core” PVC pipe, and when should I use it?
Foam core PVC pipe has a multi-layer construction with a solid inner and outer shell and a lightweight foam middle. It’s intended for drainage (DWV) use where high strength isn’t required. It is lighter and easier to handle, but shouldn’t be used for pressurized systems.
