The Balboa 1-1/2" Slip x Slip / 2" Spigot Union (11-3440) from Balboa Water Group is a versatile spa plumbing fitting designed to simplify repairs and replacements in Balboa-based systems. With configurable ends on each side, it accommodates both slip and spigot connections in either 1-1/2" or 2" sizes, making it a flexible choice for a wide range of spa installations.

• Adaptive end configurations: Each connection can be set as Slip (s) or Spigot (spg) and supports 1-1/2" or 2" piping, enabling quick matching of existing lines during maintenance or retrofits.
• Broad replacement compatibility: This union replaces multiple Balboa part numbers, including 11-3440, 14916, 21049-150-000, 316917, 400-3090, 562780, and 9170-052, simplifying inventory decisions and ensuring reliable replacements.
• Designed for Balboa spa systems: Built to integrate with Balboa components, pumps, heaters, and control assemblies, so you can maintain consistent performance across your spa hardware.
• Service-friendly by design: The union is intended to be removable, enabling easier access to internal components for maintenance without a full system teardown.

Who is this for? Spa owners, service technicians, and DIY enthusiasts who service Balboa-based hot tubs and spas will appreciate its flexibility and wide compatibility. If you’re replacing a worn or leaking union in a Balboa system, this part consolidates multiple sizing options into a single, adaptable solution.

Practical use cases include replacing a faulty union on a Balboa heater or pump, retrofitting an aging spa with newer Balboa components, or upgrading piping to accommodate a mix of 1-1/2" and 2" lines without swapping several fittings.

Installation tips (high level): confirm the end types and sizes before installation, align the piping to ensure smooth engagement, and follow standard spa plumbing practices to achieve a clean, leak-free seal.
