Waterway 411-9120 2″ Sweep Elbow (Slip × Spigot, PVC)
The Waterway 411-9120 is a 90° sweep elbow fitting designed for 2″ pool and spa plumbing. It’s used to smoothly change the direction of piping while maintaining a full-flow path and minimizing turbulence — ideal for circulation, return, suction, or spa plumbing loops.
Key Features
- 2″ slip (socket) inlet × 2″ spigot (male) outlet — simple way to connect slip-fit PVC to threaded/spigot-fit lines.
- Sweep-style 90° bend — reduces flow resistance and water turbulence compared to sharp-angle elbows.
- NSF-approved pool-rated PVC construction — chemical-resistant and durable for long-term outdoor pool use.
- White finish — common standard for pool plumbing, easy to glue or solvent-weld into existing systems.
- Versatile use — compatible with most 2″ PVC return, suction, and spa plumbing runs in residential and commercial pool systems.

When & Why to Use It
Use the 411-9120 when you need to bend a 2″ PVC line 90° — especially when transitioning from glued (slip) PVC to a threaded/spigot line (e.g. toward valves, unions, or equipment). The sweep design helps maintain water flow efficiency and reduces strain on pipes, making it a smart choice for pump returns, heater lines, spa plumbing, or general pool circulation systems.
Installation Tips
- Apply PVC primer and solvent cement to the slip/socket end per manufacturer instructions for a secure, watertight bond.
- Ensure proper alignment so the spigot end mates cleanly with the downstream fitting or bulkhead to avoid stress or misalignment.
- Allow full cure time for adhesive before pressurizing the plumbing system.
- Support the elbow and adjacent piping to prevent future stress on joints — especially if equipment is heavy or rigid.
