Hayward SP1485 – 1½″ Self-Aligning Union Elbow
Product Overview
This union elbow features 1½″ male threads on both ends, a 90° sweep design and self-aligning construction. Constructed of corrosion-resistant ABS plastic, it serves as a direct-replacement plumbing component for in-ground pool systems that require a compact, high-quality elbow union.
Key Features
- 1½″ male threaded connection on both ends (MIP × MIP).
- 90° sweep elbow shape for tight plumbing bends.
- Self-aligning union design to reduce installation strain and misalignment.
- Manufactured in durable ABS plastic, suitable for poolside chemical environments.
- Ideal for replacing old or leaking union elbows in pump-filter return lines.
Technical Specifications
- Part Number: SP1485
- Material: ABS plastic
- Connection Size: 1½″ Male Thread × 1½″ Male Thread
- Orientation: 90° elbow sweep
- Application: In-ground pool plumbing union elbow for return or pump side
Applications & Compatibility
This elbow union is designed for use where a 1½″ male-to-male threaded connection is needed at a 90° angle. Commonly found in in-ground pool pump and filter return plumbing. Verify your existing thread size and system configuration to ensure compatibility.
Installation Instructions
- Shut off the pool pump and relieve pressure from the plumbing line before servicing.
- Remove the existing elbow union and clean the threaded connections.
- Apply pool-safe thread sealant or tape as required for your system.
- Thread the SP1485 into place, ensuring the self-aligning union properly seats and aligns.
- Tighten the union hand-tight then secure per manufacturer guidance. Restore circulation and inspect for leaks.
Troubleshooting
- Leak at union connection: Verify threads are clean and sealed correctly, ensure the union is fully seated and aligned.
- Union misalignment or stress cracking: Confirm the self-aligning union is used to relieve stress, and ensure plumbing alignment is correct before tightening.
- Poor fit or thread mismatch: Re-check that both ends are 1½″ male and compatible with your existing plumbing fittings.
Maintenance Tip
During routine pool servicing inspect the union elbow for cracks, chemical damage or worn threads. Replacing worn plumbing elbows like the SP1485 helps prevent leaks and reduce downtime.
