Standard 1¼ Inch PVC Waste Plug

1¼ Inch Waste Plug

The Standard PVC Waste Plug provides a reliable, watertight seal for 32mm drainage outlets in residential and commercial plumbing systems. This uPVC component fits standard washbasin traps and manifold branch pipes. It prevents leakages and blocks sewer gases from escaping through unused ports.

Built for the Job

Plumbers and site supervisors frequently use this fitting during the second-fix stage of bathroom installations. It serves as a permanent cap for secondary inlets on bottle traps or as a temporary seal during system pressure tests. The robust construction handles the thermal expansion common in domestic hot water discharge. Maintenance teams in commercial facilities keep these in stock to replace lost or damaged basin caps quickly. This component ensures the drainage stack remains airtight and functional under daily use.

• Sealing unused side-inlets on multi-entry basin traps and waste manifolds.

• Capping off drainage lines during renovation or phased building construction.

• Replacing worn threaded plugs in high-traffic public washroom facilities.

On-Site & Workshop Notes

• Apply a thin layer of silicone grease or PTFE tape to the threads for a superior seal.

• Avoid over-tightening with heavy wrenches to prevent cracking the female housing on plastic traps.

• Verify that the receiving orifice is free of debris before threading the cap into place.

• This 32mm size is standard for washbasins; kitchen sinks typically require the larger 40mm variant.
