The Waterway 400-2000 pump union assembly is designed for compatible pump plumbing applications using a 1 inch slip by 1 inch slip configuration. A full union assembly in this style is useful because it restores a removable pump connection while keeping the surrounding plumbing in a straightforward rigid-line format.

Slip-by-slip unions are especially practical where solvent-weld plumbing is already in place and future service access still matters. Replacing the assembly with the correct Waterway part helps preserve a cleaner installation and maintains easier pump removal later.

For compatible pump repairs and plumbing replacement work, this Waterway union assembly is a practical choice when a 1 inch slip-to-slip serviceable connection is required.

  • Waterway pump union assembly
  • 1 inch slip x 1 inch slip configuration
  • Useful for serviceable rigid pump plumbing connections
  • Helps simplify maintenance and future equipment removal
  • Supports cleaner and more dependable installation
