A 2-inch PVC P-trap is used in compatible drain, waste, and vent (DWV) piping to hold a water seal that helps block sewer gases. For a single solvent-weld installation, consider the NIBCO or Asterbacks one-pack model; for multiple installations, the Asterbacks five-pack or SUPPLYGIANT 20-pack may suit the quantity needed. The Canplas model is identified as a union-style trap. Check pipe type, connection style, and local plumbing requirements before choosing.
| Product | Best For | Connection Or Quantity |
|---|---|---|
| NIBCO U4885 | Single DWV fitting | 2-inch hub x hub, solvent weld |
| Asterbacks one-pack | One Schedule 40 connection | 2-inch solvent weld |
| Canplas 193212E | Buyers seeking a union-style model | 2-inch, union identified |
| Asterbacks five-pack | Several similar projects | Five 2-inch traps |
| SUPPLYGIANT 20-pack | Bulk purchasing | Twenty 2-inch fittings |
NIBCO 2-Inch PVC DWV P-Trap
The NIBCO Fig. No. U4885 is a 2-inch PVC DWV P-trap with hub connections at both ends and a solvent-weld installation style. Its stated purpose is to create a water seal in a DWV system to help prevent sewer gases from entering occupied spaces. The listing describes PVC-DWV construction as corrosion-resistant, strong, and lighter than metal fittings.
Best for: A buyer needing one named-brand, hub-by-hub DWV trap for a compatible solvent-weld setup. It was selected for its clearly stated trap function and connection type. Limitation: The provided product details do not specify a temperature rating or dimensional measurements beyond the 2-inch size, so confirm those requirements separately.
Asterbacks 2-Inch P-Trap, One Pack
This Asterbacks trap has solvent-weld joints and is described as suitable for 2-inch Schedule 40 PVC pipe. The listing gives a 2-inch inner diameter and 2-3/8-inch outer diameter for the pipe connection. It also describes the PVC as lightweight and resistant to impact, frost, and corrosion. Installation calls for primer and solvent cement, and the stated maximum operating temperature is 140°F.
Best for: A single connection where the specified Schedule 40 pipe dimensions and solvent-weld method match the project. It was selected for its specific pipe-size and installation details. Limitation: It requires primer and solvent cement; it is not described as a threaded or removable connection.
Canplas 2-Inch PVC DWV P-Trap
The Canplas 193212E is listed as a 2-inch white PVC DWV P-trap with a union. Its product details describe injection-molded, non-toxic PVC and a service temperature rating of 140°F (60°C). The listing says it is normally used only in the drainage portion of a DWV system.
Best for: Buyers specifically comparing a union-style trap for a drainage application. The stated material and temperature rating help identify whether it matches a project’s basic requirements. Limitation: The provided features do not explain the union configuration or connection dimensions. Confirm the fitting ends and installation requirements before ordering.
Asterbacks 2-Inch P-Trap, Five Pack
This five-pack uses the same stated 2-inch solvent-weld design as the Asterbacks one-pack. The listing specifies compatibility with 2-inch Schedule 40 PVC pipe, with a 2-inch inner diameter and 2-3/8-inch outer diameter. It describes the PVC as resistant to impact, frost, and corrosion, and gives a maximum operating temperature of 140°F. Primer and solvent cement are required for installation.
Best for: Multiple similar connections where all five fittings are needed and the specified pipe dimensions are a match. It was selected as a quantity option rather than a different connection style. Limitation: The pack may be unnecessary for a one-trap repair, and the solvent-weld joints are not described as removable.
SUPPLYGIANT 2-Inch P-Trap, 20 Pack
SUPPLYGIANT lists a 20-pack of white PVC DWV P-traps with 2-inch solvent-weld joints. Its features describe corrosion-resistant PVC and a water seal intended to block sewer gases while allowing drainage. The listing also mentions compatibility with standard 4-inch DWV piping, which appears inconsistent with the stated 2-inch fitting size.
Best for: Bulk purchasing when a project requires many 2-inch traps and the connection details have been verified. It was selected for its stated DWV use and large pack quantity. Limitation: Confirm the intended pipe size with the seller or product documentation before purchase because the listed 4-inch compatibility claim conflicts with the 2-inch product description.
Buying Guide: How To Choose a 2-Inch PVC P-Trap
Does the connection style match your pipe?
Check whether the trap uses hub connections for solvent welding or a union-style configuration. A solvent-weld fitting generally requires compatible pipe, primer, and cement; the Asterbacks listings explicitly call for those installation materials. Do not assume that every 2-inch fitting uses identical connection dimensions. Compare the product details with the pipe and fittings already in the project.
Is the trap intended for the right system?
Several options are explicitly described as DWV fittings. The Canplas listing says the product is normally used in the drainage portion of a DWV system, while the Asterbacks listings describe broader uses. Confirm that a fitting is appropriate for the intended application rather than relying on the words “PVC” or “2-inch” alone. Follow local plumbing codes and applicable installation instructions.
How many traps should you buy?
Choose a one-pack for a single repair, a five-pack for several similar connections, or a 20-pack only when the project quantity justifies bulk purchasing. Larger packs do not change the connection requirements, and every fitting still needs to match the specified pipe and system.
What temperature and material details matter?
The Asterbacks products state a maximum operating temperature of 140°F, and Canplas lists a 140°F (60°C) service rating. NIBCO’s supplied features do not state a temperature rating. Compare the rating with the expected system conditions and consult the full manufacturer information when that detail is necessary.
Frequently Asked Questions
What does a P-trap do?
A P-trap holds water in its curved section. That water seal helps keep sewer gases from passing through the drain into occupied spaces.
Can I connect any 2-inch P-trap to any 2-inch pipe?
No. Confirm the pipe type, actual dimensions, and connection style. A matching nominal size alone does not establish that a fitting is compatible.
Do solvent-weld P-traps need primer and cement?
The Asterbacks listing specifies primer and solvent cement for its solvent-weld trap. Follow the fitting manufacturer’s directions for the product you select.
Is a PVC DWV P-trap suitable for every plumbing application?
No. Product listings identify intended uses and limits, and local codes may also apply. Verify the fitting is approved for the particular drainage system and installation conditions.
