Spears P106 Series PVC DWV Cleanout Plug
Best for: systems that require corrosion resistance and lightweight fit. This cleanout plug uses male NPT threads to attach to female-threaded pipes, with PVC construction offering durability and reduced weight compared with metal fittings. The plug is a straightforward option when you need reliable access to a cleanout without introducing metal into a PVC system. Caution: ensure proper threading compatibility with your pipe size to avoid leaks.
DANCO PlugAll Mechanical Test Plug
Best for: plumbers and homeowners performing drain tests or temporary sealing of cleanouts. The Expandable PlugAll fits 1-1/2 inch and 2 inch pipes, accommodating both threaded and non-threaded installations. It is especially useful during pressure or leak-testing stages of a project. Limitation: it is a temporary testing plug and not a long-term permanent seal after testing.
Lesso 3-Way ABS P-Trap With Cleanout and Plug
Best for: residential or light commercial sinks needing an integrated cleanout. This ABS P-trap features a dual HUB connection and a built-in cleanout with plug, which simplifies clog removal and pipe connections while maintaining a leak-proof design. Caution: ensure primer/cement compatibility is used with ABS to maintain a proper seal and avoid leaks at hub connections.
Lesso 1-1/2 Inch ABS P-Trap With Cleanout Plug
Best for: 1-1/2 inch residential sink drains needing a cleanout. This model offers a built-in cleanout with plug, and a durable ABS construction for resistance to corrosion and temperature changes. Choose this if you want a simple, modular design that is easy to install. Limitation: slightly more limited to ABS piping systems; verify your pipe material before purchase.
Lesso 1-1/2 Inch ABS P-Trap With Union, Cleanout
Best for: installations requiring easy maintenance with a detachable union, plus a cleanout. This design allows quick disassembly without removing connected pipes, which can save time during clog removal. Caution: ensure proper alignment when reassembling the union to prevent leaks at the joint.
Eastman 1-1/4 Inch Steel P-Trap With Cleanout
Best for: higher-durability needs and odor control in kitchens and bathrooms. This steel P-trap provides a robust metal body with a built-in cleanout, designed for universal tubular applications and compatible with typical under-sink fittings. Caution: metal traps may require different maintenance routines to prevent corrosion over long periods, especially in harsh water conditions.
NDS 41P8 PVC S&D Cleanout Plug
Best for: 4-inch drain systems needing accessible cleanout points. This plug attaches to 4-inch FPT connections, enabling straightforward access for snakes and maintenance. Caution: designed for specific pipe sizes; verify the cleanout thread standard before purchase to ensure compatibility with your drainage fittings.
Buying Guide
- Material matters: PVC is lightweight and corrosion-resistant; ABS is durable for residential environments; steel offers superior durability in high-use areas.
- Connection type: choose between male/female threads, hub connections, or union designs based on your existing piping and maintenance needs.
- Built-in cleanout: a plug-enabled cleanout can simplify future maintenance, but ensure the plug type matches your piping to avoid leaks.
- Size compatibility: verify pipe diameter (1-1/2 in, 1-1/4 in, 2 in, 4 in, etc.) and threading standard (NPT, FPT) before purchasing.
- Ease of maintenance: union joints and removable components reduce disassembly time when clearing clogs.
- Code considerations: ensure the chosen plug and trap configuration complies with local plumbing codes and standard drainage practices.
FAQs

- Which material is best for a cleanout plug? PVC is common for corrosion resistance; ABS is durable for residential use; steel offers high durability in demanding environments.
- Do all cleanouts require a plug? Not always; some systems use removable caps or unions. A plug-type cleanout is convenient for regular maintenance.
- Can I reuse an existing cleanout with a new plug? It depends on the threading and size; verify compatibility with the new plug and fittings.
- Is a built-in cleanout better than a separate plug? Built-in options can save space and simplify resealing, but ensure proper alignment and sealant use for leak prevention.
- How do I choose the right size? Measure the pipe diameter and check the thread type (NPT, FPT) or hub size to match the plug and trap.
