The MUELLER STREAMLINE PDWV4817112 is a PVC DWV cap designed to terminate or close off the end of a 1-1/2 inch drain, waste, and vent pipe. This fitting is manufactured from rigid polyvinyl chloride, making it resistant to corrosion, chemical attack, and the moisture-heavy conditions typical of residential and light commercial plumbing systems. It installs using solvent cement to form a permanent, leak-free seal on the pipe end. Plumbers and pipefitters use this cap to plug unused branch openings, test sections of a DWV system, or permanently close off pipe runs during rough-in or remodel work.
This cap is suited for residential and light commercial drain, waste, and vent applications. It is used wherever a 1-1/2 inch PVC DWV pipe end requires a clean, secure termination. Typical scenarios include capping stub-outs during rough-in inspections, closing off decommissioned fixture connections, or sealing test points after pressure testing a drain system. It is installed by licensed plumbers and pipefitters following applicable local plumbing codes.
Designed as an OEM-style replacement and standard fitting for 1-1/2 inch PVC DWV Schedule 40 drain, waste, and vent piping systems.
Installation is performed by a licensed plumber in accordance with the applicable International Plumbing Code or local equivalent. Before installing, ensure the pipe end is cut square, deburred, and cleaned with the appropriate PVC cleaner prior to applying solvent cement. Apply a suitable PVC primer and solvent cement to both the pipe end and the socket of the cap, then push and twist to seat the fitting fully. Allow the joint to cure for the time specified by the cement manufacturer before restoring flow or pressure to the line.
