A 3-inch DWV P-trap helps maintain a water seal in a gravity-fed drain system, blocking sewer gases while allowing wastewater to flow. The Charlotte Pipe trap is a straightforward choice for a single installation, while SUPPLYGIANT’s 10-pack suits buyers needing multiple fittings. Canplas offers white PVC construction, Genova is a Schedule 40 option, and EFIELD provides a low-profile two-piece listing. Confirm the connection type, pipe sizing, temperature limits, and local plumbing requirements before choosing.

Charlotte Pipe 3-Inch DWV P-Trap
This Charlotte Pipe fitting is a black 3-inch P-trap with a solvent-weld joint for drain, waste, and vent applications. The listing also identifies sanitary drain, sewer, and storm uses. It is intended for non-pressure systems and for applications where the system will not exceed 140°F.
Best for: A buyer who needs one solvent-weld DWV trap and wants a clearly stated temperature and pressure-use limit. It was selected as a direct match for the 3-inch P-trap search.
Consider: This fitting is not intended for pressure use. Check that the system’s pipe material and connection arrangement suit a solvent-weld fitting before purchasing.
SUPPLYGIANT 3-Inch PVC P-Trap, 10-Pack
This listing is for ten white PVC DWV P-traps with solvent-weld H x H joints. The supplied product details describe corrosion-resistant PVC and explain that the trap creates a water seal to block sewer gases. The listing also states that the 3-inch fitting is designed for compatibility with standard 4-inch DWV piping.
Best for: Contractors or property owners sourcing several fittings for a project. The pack quantity is its main distinction among these options.
Consider: The stated compatibility with 4-inch DWV piping makes it especially important to verify actual nominal pipe and fitting dimensions before ordering. Do not assume that a 3-inch fitting connects directly to every 4-inch pipe.
Canplas 193203 3-Inch PVC P-Trap
The Canplas 193203 is a white PVC DWV P-trap, injection molded from non-toxic PVC according to its product details. It has a stated service temperature rating of 140°F and is normally used in the drainage portion of a DWV system. Its listed connection is solvent-weld, H x H.
Best for: Buyers who want a white PVC trap for a drainage application and need a listed temperature rating. It provides a clear alternative to the black Charlotte Pipe fitting.
Consider: The manufacturer’s described use is the drainage portion of a DWV system only. Confirm that this use matches the intended location and applicable plumbing rules.
Genova 78530 Schedule 40 P-Trap
The Genova 78530 is listed as a 3-inch Schedule 40 PVC P-trap. The product information identifies it as made in the United States, but provides fewer installation details than several other options in this list.
Best for: A buyer specifically comparing 3-inch Schedule 40 P-traps. It was included because the listing explicitly states both its size and Schedule 40 designation.
Consider: The supplied details do not specify joint style, temperature rating, or pressure-use limits. Check the product documentation and fitting configuration before selecting it for a particular installation.
EFIELD 3-Inch Low-Profile P-Trap, 2-Pack
EFIELD’s listing describes two 3-inch low-profile PVC DWV P-traps with H x H connections. The fittings are intended for gravity-fed, non-pressure waste systems and are installed with solvent cementing, among other joining methods listed by the manufacturer. The stated maximum system temperature is 140°F.
Best for: Buyers who want a low-profile design and need two fittings. Its listed dimensions and installation method should be checked against the project layout.
Consider: The fittings are not intended for pressure use. Confirm that the low-profile configuration fits the available space and connection requirements.
Buying Guide: How to Choose a 3-Inch P-Trap
What does a P-trap do?
A P-trap holds water in its curved section. That water forms a seal that helps block sewer gases from moving back through the drain. The products covered here are described for DWV or gravity-fed drainage uses, not pressurized plumbing.
Which connection style do you need?
Check how the trap joins the existing piping. Several listed options use solvent-weld connections, which require compatible components and solvent cement. The EFIELD listing also identifies H x H connections. Verify joint style and pipe sizing rather than relying on the product’s general 3-inch label alone.
Should you choose a single fitting or a pack?
A single fitting can suit a one-off repair or installation. The SUPPLYGIANT listing includes ten traps, while EFIELD is listed as a two-pack. Compare the quantity with the project plan and check each fitting’s connection and application details.
Do material and temperature limits matter?
Yes. These products include PVC options, while Charlotte Pipe is described as black DWV material. Charlotte Pipe and Canplas list a 140°F limit; EFIELD also specifies systems not exceeding 140°F. Do not use a fitting beyond its stated limits or for pressure service if the listing excludes pressure use.
What should be checked before installation?
Confirm the nominal pipe size, joint type, drainage-system application, available clearance, temperature limits, and local plumbing requirements. When a listing provides limited specifications, consult its product documentation or a qualified plumbing professional before installation.
Frequently Asked Questions
Can a 3-inch DWV P-trap be used for pressurized plumbing?
Not if its product details state that it is not intended for pressure use. The listed Charlotte Pipe and EFIELD fittings explicitly exclude pressure applications.
Does every 3-inch P-trap connect to 3-inch pipe?
Not necessarily. Check the fitting’s connection type and actual pipe sizing. The SUPPLYGIANT listing mentions compatibility with standard 4-inch DWV piping, so verify dimensions carefully.
What does H x H mean on a P-trap listing?
It identifies the listed connection configuration. Confirm that the connection style matches the piping and installation method for the project.
Why does a P-trap need water in it?
The water held in the trap forms a seal that helps keep sewer gases from passing back through the drain.
