Before you buy — quick checklist

  • Confirm your Wavemaster pump is Version 2 of the 7000 or the 9000 — the V1 Wavemaster 7000 uses a different O-ring
  • Inspect the existing O-ring and seal plate before ordering to confirm the leak source is at the seal plate junction and not elsewhere
  • Verify the SKU 70942 against your existing O-ring or your pump's parts diagram in the Hot Spring owner documentation
  • Have silicone-based lubricant on hand before installation — do not use petroleum-based lubricants, which will degrade the rubber
  • Ensure you can safely drain and de-energize the spa before beginning work

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
