Waterway 411-9100 – 1½" Spigot x 1½" Slip PVC 90° Sweep Elbow

Product Overview

This Waterway 411-9100 sweep elbow is a 90-degree PVC fitting designed for pool and spa plumbing. It features a 1½" socket (slip) connection on one end and a 1½" spigot connection on the other, fitting standard Schedule-40 plumbing. It enables smooth fluid transition while reducing hydraulic turbulence in circulation systems.

Key Features

  • 1½" socket (slip) x 1½" spigot configuration
  • 90° sweep elbow design for gentler directional change in plumbing
  • Made from PVC suitable for pool/spa chemical environments
  • Provides direct OEM replacement fit for Waterway-series plumbing components
  • White finish blends with standard pool plastic plumbing systems

Technical Specifications

  • Part Number: 411-9100
  • Connection Sizes: 1½" spigot x 1½" slip
  • Standard: Schedule 40 equivalent PVC
  • Color: White

Applications & Fitment

Ideal for use in pool and spa plumbing where a 90-degree directional change is required and one end uses a socket/slip connection while the other uses a spigot. Commonly used in PVC return lines, pump suction plumbing, or filter plumbing runs where OEM compatibility with Waterway plumbing parts is needed.

Installation Notes

  • Ensure plumbing is cut square and deburred before solvent cementing.
  • Dry-fit the elbow to confirm alignment and avoid stress on fittings.
  • Use PVC primer and solvent cement rated for pool/spa service.
  • After curing the joint, pressure test the plumbing system and inspect for leaks.

Troubleshooting

  • Leak at joint: Check that the correct glue/primer was used, joint was fully inserted, and slot of spigot is aligned.
  • Flow restriction: Ensure the elbow does not add unnecessary sharp bends near pump or filter; reposition if possible.
  • Mismatch size: Confirm the spigot/slip sizes match existing plumbing – 1½" spigot x 1½" slip.

Maintenance Tip

Inspect this fitting when servicing the pump or filter assembly. Check for stress cracks near the elbow due to vibration or thermal cycling. Reassess solvent-cement joints annually in chemical-intensive systems and replace if signs of degradation appear.
