A floor drain with a P-trap can help keep sewer odors from entering a room while giving water a route to the drain line. The right choice depends on more than the drain opening: check the pipe size, connection type, trap design, installation space, and local plumbing requirements. These three options include one drain with detailed trap specifications and two Sioux Chief listings with less information, so compare the confirmed details carefully before you buy.

Sioux Chief CS14-R: A 2-Inch Drain With a Solvent-Weld Connection
The Sioux Chief CS14-R is listed as a PVC trap and floor drain with a 2-inch solvent-weld connection. That connection detail is useful when you are matching the drain to a compatible PVC pipe installation. A solvent-weld joint is a permanent connection, so you will want to confirm pipe size, layout, and fit before joining the parts.
The available product details are brief. They do not specify the strainer style, trap-seal depth, drain-body dimensions, or whether the trap is integral to the drain. That makes this a less certain choice if you need those details to plan an installation. Check the product listing or manufacturer information before buying, especially if you are replacing an existing drain.
Compared with the PROFLO, the CS14-R has fewer listed features, but its connection type is clearly stated. It may suit a project where a 2-inch solvent-weld PVC connection is the main requirement and the remaining dimensions have already been confirmed.
Pros:
- Specifies a 2-inch connection.
- Uses a PVC solvent-weld connection.
- Listed as a combined trap and floor drain.
Cons:
- Available details do not confirm trap-seal depth or strainer design.
- Confirm dimensions and installation compatibility before ordering.
Verdict: Choose the CS14-R if you need a 2-inch PVC solvent-weld drain and have verified that its unlisted dimensions and trap details suit your installation.
PROFLO PF800P: An Integral-Trap Drain With More Specified Features
The PROFLO PF800P is a 2-inch PVC floor drain with an integral trap. Its listed features include a 3-inch trap seal, a 3-3/4-inch-deep sump bowl, a polypro strainer, and a one-piece drain body. It is specified to fit 2-inch Schedule 40 pipe, giving you more information to compare against your plumbing layout than the other options in this group.
The listing also describes an installed backwater device intended to help prevent backflow through the floor drain. That feature may matter in a location where backflow is a concern, but it should not be treated as a substitute for checking plumbing requirements for your property. Confirm that the device and drain are appropriate for your application and local code.
The integral design brings the drain and trap together in one body, which can simplify product matching when you want those components combined. The trade-off is that you need to confirm the complete unit’s dimensions and connection arrangement before installation; the product description does not provide every measurement a plumber may need.
Pros:
- Lists a full 3-inch trap seal.
- Specifies a fit for 2-inch Schedule 40 pipe.
- Includes an integral trap and one-piece drain body.
- Includes a polypro strainer and a backwater device.
Cons:
- Confirm overall dimensions and installation fit before purchase.
- The added backwater feature does not remove the need to check local plumbing requirements.
Verdict: The PF800P is the strongest match if you want an integral trap and value having the trap seal, pipe fit, and backwater device described in the product details.
Sioux Chief PVC 2-Inch P-Trap Floor Drain: A Basic Option to Verify
This Sioux Chief listing is titled as a PVC 2-inch P-trap floor drain. Beyond that, the supplied product information does not describe its connection type, trap-seal depth, strainer, or body dimensions. Those missing details make it harder to judge fit or compare it directly with the PROFLO model.
The title may make this option worth checking if you are looking for a 2-inch PVC floor drain with a P-trap. Still, do not assume its connection method or dimensions match the CS14-R simply because both are Sioux Chief products listed for 2-inch PVC. Confirm the model specifications and compatibility with your pipe before purchasing.
Against the other two choices, this model has the least information available for planning. It could work for a project where its exact specifications are verified through the listing or manufacturer, but the PROFLO is easier to assess from the details provided.
Pros:
- Listed as a PVC floor drain with a P-trap.
- The title identifies it as a 2-inch model.
- May be worth comparing when you have confirmed the installation details.
Cons:
- No description is provided for connection type, trap seal, or strainer.
- Product dimensions and fit details need to be confirmed before purchase.
Verdict: Consider this Sioux Chief drain only if you can verify its full specifications and confirm that they match your plumbing setup.
How to Choose a Floor Drain With a P-Trap
Match the Pipe Size and Connection
Start by checking the drain outlet size and the pipe already installed at the location. A product described as 2 inches may still differ in connection style. For example, the CS14-R specifies a 2-inch PVC solvent-weld connection, while the PROFLO is listed to fit 2-inch Schedule 40 pipe. Confirm that the drain’s connection is compatible with your pipe and installation method before ordering.
Check the Trap Arrangement and Seal
A P-trap holds water that helps block sewer gases from passing back through the drain. Some products combine the trap and drain in one body, while other setups may use separate plumbing components. Look for clear information about whether the trap is integral and, when listed, the trap-seal depth. The PROFLO specifies a 3-inch trap seal; the supplied information for the Sioux Chief models does not provide that measurement.
Measure the Space Below and Around the Drain
Compare the drain’s overall dimensions and required installation depth with the space available beneath your floor. Check the sump or bowl depth, pipe direction, and room for connections and maintenance. If the listing does not provide these measurements, ask the seller or manufacturer rather than relying on the product title alone.
Consider the Strainer and Drain Opening
The strainer affects the visible opening and helps keep larger debris out of the drain. Check its material, shape, and dimensions against your needs, along with how it fits the finished floor. The PROFLO listing identifies a polypro strainer, but the supplied details for the Sioux Chief models do not describe their strainer designs.
Evaluate Backflow Protection Carefully
A drain with a backwater device may be useful for some applications, but the right protection depends on the plumbing system and local requirements. The PROFLO listing specifies a device intended to prevent backflow through the floor drain. Confirm how it works with your setup and whether additional backwater protection is required; consult a qualified plumbing professional when needed.
Check Installation Rules Before You Buy
Floor-drain requirements can vary by location and by the type of room or building. Review local plumbing code and the product’s installation instructions before choosing a drain. If the work involves a new drain line, a change to existing plumbing, or uncertainty about trap placement, have a licensed plumber confirm the design.
Frequently Asked Questions
What does a P-trap do in a floor drain?
A P-trap holds a small amount of water in the drain line. That water acts as a barrier to help keep sewer gases from coming back through the floor drain. The trap must be installed and maintained as directed for it to work as intended.
Is an integral trap the same as a separate P-trap?
An integral trap is built into the drain body, while a separate P-trap is a distinct plumbing component connected to the drain piping. The PROFLO PF800P is listed as having an integral trap. Check the product instructions and your plumbing layout to see which arrangement is appropriate.
Does a 2-inch floor drain fit every 2-inch pipe?
Not necessarily. Pipe material, schedule, and connection style can affect compatibility. Check the product’s connection specifications as well as the pipe size. The PROFLO is listed for 2-inch Schedule 40 pipe, and the Sioux Chief CS14-R specifies a 2-inch PVC solvent-weld connection.
Which option provides the most installation detail?
The PROFLO PF800P has the most specified features in the supplied product information, including its 2-inch Schedule 40 pipe fit, 3-inch trap seal, sump-bowl depth, strainer, and backwater device. You will still need to confirm its overall dimensions and suitability for your project.
Should I choose a floor drain with a backwater device?
It depends on your plumbing setup and local requirements. A backwater device is intended to help limit backflow through the drain, but it may not meet every system’s needs on its own. Check applicable code and consult a plumber if backflow is a concern.
What should I do if a product listing does not show dimensions?
Ask the seller or manufacturer for the installation dimensions, outlet details, and instructions before buying. This is especially important for the Sioux Chief PVC 2-inch P-trap floor drain, whose supplied description does not include those specifications.
Final Recommendation
For shoppers who want the clearest set of listed features, the PROFLO PF800P is the most straightforward choice in this comparison: it specifies an integral trap, a 3-inch trap seal, a fit for 2-inch Schedule 40 pipe, and a backwater device. The Sioux Chief CS14-R is worth considering when you specifically need its 2-inch PVC solvent-weld connection. Choose the other Sioux Chief model only after verifying its connection, dimensions, and trap details. For any option, confirm compatibility with your plumbing and local code before installation.
