The Waterway 417-5180 heater union tailpiece is designed for compatible heater applications using a 2 inch buttress thread connection with a 3/4 inch slip or 1 inch spigot outlet configuration. This specialized tailpiece is useful where the heater union must interface with a smaller downstream plumbing path while still matching the original heater-side thread design.

The dual outlet-style flexibility makes this Waterway part especially practical in repair and retrofit work where the exact surrounding plumbing may vary. It allows the union connection to remain serviceable while better matching the intended line size transition.

For compatible heater plumbing service, this Waterway tailpiece is a practical option when a 2 inch buttress-thread heater connection must transition to a smaller branch format.

  • 2 inch buttress thread with 3/4 inch slip or 1 inch spigot outlet configuration
  • Useful for heater-side union transitions into smaller plumbing
