Customer-Facing Q&A

Q: What is a union bottom assembly used for?
A: It’s the lower portion of a union connection that helps attach plumbing to Jandy equipment and allows you to disconnect equipment for service without cutting pipes.

Q: How do I know if I need to replace mine?
A: Common signs include visible cracks, persistent leaks at the union, stripped threads, or a union that won’t tighten/seal properly.

Q: Does this include the o-ring or gasket?
A: Some unions require a separate o-ring/gasket. If your union is leaking, it’s a good idea to replace the o-ring at the same time (check your equipment diagram for the correct seal part).

Q: Is this part compatible with all Jandy equipment?
A: It’s designed for Jandy Pro Series unions, but compatibility can vary by model. Match the part number (R0466500) to your equipment’s manual/parts diagram to confirm fit.

Q: Can I install this myself?
A: Many pool owners can handle union component replacement if the system is safely powered down and depressurized. If you’re unsure, a pool professional can help.
