The Waterway 3711621-1D Executive pump is designed for compatible applications and features a 4.0 HP motor rated at 12.0 amps in a single-speed configuration. A pump like this is useful because it restores the full operating assembly when the original pump is no longer reliable and a complete replacement is the cleaner repair path.

Executive models are often chosen when preserving original equipment fit and pump family compatibility matters. This Waterway single-speed unit is a strong replacement option when the existing 4.0 HP pump has reached the point where replacing the full assembly makes more sense than rebuilding individual components.

For compatible pump repairs, this Waterway Executive pump is a practical replacement when a 4.0 HP single-speed 12.0 amp pump is needed.

  • Waterway Executive pump
  • 4.0 HP single-speed configuration
  • Rated at 12.0 amps
  • Helps restore complete pump operation
  • Useful for direct replacement work
