Connecting Two Pumps

Our pumps are designed to run from a single transformer. The below outlines what you need & how you do this.

To correctly wire up SP22S – Two Automatic Pumps (or SP2B & SP2U Upgrade Pump) you will need:

  • Automatic Pump x 2
  • Transformer
  • 4 Way Cable (Power Bridge)
  • 3 Way Cable

Step 1

Use the 3-way cable to take the power from the transformer to both flow switches. Both blue lights will illuminate so you know you have the first bit right and you are half way there.
