About this pressure switch

The Tecmark 3037P pressure switch is a Single Pole Single Throw (SPST) sensor designed for spa and hot tub systems that require reliable pressure monitoring. This 1 amp switch activates between 1-5 PSI and features standard 1/8" NPT threading for easy installation in most spa plumbing configurations. Built by Tecmark, a trusted name in spa controls, this OEM-quality pressure switch helps resolve common heater and operational issues including HH, ICE, and OH error codes.

At Bubbles Supply, we guarantee this pressure switch is an exact fit for your spa system and back it with our comprehensive 1-year warranty. Every order ships the same day to minimize your spa downtime. Professional installation is recommended to ensure proper calibration and system safety. Always verify your existing switch specifications and thread size before ordering to confirm compatibility with your spa's pressure monitoring requirements.

Before you buy — quick checklist

  • Confirm your existing pressure switch is rated for 1-5 PSI activation range — not all spa pressure switches share the same trip point
  • Verify your existing switch uses 1/8" NPT male threads before ordering
  • Confirm your system requires an SPST (Single Pole Single Throw) switch, not SPDT
  • Check the amperage rating on your current switch — this unit is rated for 1 amp
  • Inspect the switch port on your manifold or plumbing tee for damage or stripped threads before reinstalling

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