The best two-way sewer cleanout depends on the pipe size and whether the fitting is intended for a DWV or sewer application. The Charlotte Pipe 4-inch fitting is a clear option when a 4-inch DWV cleanout is needed, while its 3-inch models suit buyers looking for that size. Canplas offers a PVC DWV fitting and a separate 4-inch sewer fitting. Check the product’s stated use and size before choosing; these listed fittings are not pressure-rated products.

Buying Guide: How to Choose a Two-Way Sewer Cleanout
Which size should you choose?
Start with the size required by the existing pipe or installation plan. The listed Charlotte Pipe options are 3 inches and 4 inches; the Canplas sewer fitting is identified as 4 inches. The Canplas DWV listing does not provide a size in the supplied details, so confirm its dimensions before choosing it.
Do you need a DWV or sewer fitting?
Match the fitting’s stated application to the system. DWV fittings are listed for drain, waste, and vent applications, while the Canplas 4-inch model is specifically identified for PVC sewer use. Some products also list sewer or storm drainage applications. When the distinction matters, check the product’s full specifications and follow applicable plumbing requirements.
How many cleanouts are needed?
Choose a single-piece product when one fitting is required. The Charlotte Pipe 3-inch model is also offered in a 10-unit box, which is better suited to buyers who need several matching fittings. Confirm the quantity in the package listing before ordering.
What temperature and pressure limits matter?
The listed Charlotte Pipe fittings are not intended for pressure use and are specified for systems that do not exceed 140°F. The Canplas options also state a 140°F service-temperature limit. Do not select these products for conditions outside their stated limits.
What should you check before installation?
Verify size, system type, material, and connection requirements before buying. For the Canplas 4-inch sewer cleanout, the details specify approved PVC primer and solvent cement for PVC joints. Check current product documentation and local code requirements for the installation.
