The MUELLER STREAMLINE 6001 is a 1-1/2 inch PVC DWV end cleanout adapter designed for drain, waste, and vent piping systems. This straight-type cleanout fitting connects via a spigot by female threaded end connection and includes a cleanout nut. Manufactured from PVC to ASTM D2665, F1498, D331, and D1784 specifications, it delivers strong chemical and corrosion resistance. Smooth interior walls reduce scaling and maintain free flow through the drain line. Plumbers and pipefitters install this fitting where access to the drain line is required for cleaning or inspection.
This cleanout adapter is suited for residential and light commercial DWV applications where code-required cleanout access points are needed. The spigot end integrates directly into standard PVC DWV piping, while the female threaded end accepts a matching cleanout plug for sealed access. It is appropriate for chemical-resistant drain applications in addition to standard waste and vent service. Consistent dimensional tolerances ensure compatibility with standard PVC DWV pipe and fittings.
Designed as an OEM-style replacement and new-installation fitting for 1-1/2 inch PVC DWV drain, waste, and vent piping systems meeting NSF 14 and UPC requirements.
Installation is performed by licensed plumbers in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and ensure the drain line is depressurized and clear before beginning work. Use appropriate PVC primer and solvent cement on the spigot connection per the adhesive manufacturer guidelines. Do not overtighten the threaded cleanout plug, as PVC threads can crack under excessive torque.
