  Replacement Notes

If you’re replacing an existing Hi‑Flo II pump:

• The wet end and unions are usually compatible across HP sizes

• The SD‑07‑1N may be replaced by newer Waterway models such as:

  • SD‑10‑1N (1.0 THP)

  • SD‑05‑1N (0.5 THP)

• Waterway often re‑labels pumps for pool brands, so your pump may have a different sticker but the same internals

  Installation Notes

• Top‑discharge pumps are ideal when plumbing rises directly into the filter

• Always replace the pump‑to‑filter o‑ring when swapping pumps

• Check amperage compatibility with your existing circuit
