Questions & Answers
Is this a genuine original part?
Yes, this is a genuine Seaflo replacement part, manufactured specifically for the 33-Series pump range to ensure correct pressure calibration and electrical compatibility.
How do I know if it is compatible?
We recommend checking the model number on your pump. If your pump belongs to the 33 series and has a 45 PSI shut-off rating, this switch is the correct fitment.
What symptoms indicate a faulty pressure switch?
If your pump fails to turn on when a tap is opened, or if it continues to run and won't shut off once the tap is closed (despite no leaks in the system), the pressure switch typically needs replacement.
Note: Always disconnect power to your water system before replacing electrical components. Verify your pump series before purchasing.
