About this pressure switch

The Tecmark 4098P pressure switch is a critical spa sensor that monitors water pressure levels to control pump and heater operation in hot tubs and swim spas. This SPST (single pole, single throw) switch activates at 1-6 PSI pressure range and features a 1/8" NPT threaded connection for secure plumbing integration.

Built to Tecmark's OEM specifications, this 1-amp rated pressure switch ensures reliable performance in demanding spa environments. The 4098P effectively prevents dry-fire conditions by shutting down heating elements when water pressure drops below safe levels. At Bubbles Supply, we guarantee an exact fit for your spa system and offer same-day shipping on all in-stock sensors, backed by our comprehensive 1-year warranty. Professional installation recommended—verify your existing switch's pressure range and electrical specifications before replacement to ensure proper system operation.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Heater won't fire even with pump running
  • Spa displaying HH, ICE, or OH error codes
  • Heater shuts off intermittently during normal operation
  • Spa goes into protective lockout with adequate water flow present
  • Dry-fire fault triggered despite normal water pressure

Not sure if this is your problem? Try our diagnostic centre or .

Before you buy — quick checklist

  • Confirm your existing switch is rated in the 1–6 PSI activation range — do not assume all pressure switches are interchangeable
  • Verify the port connection is 1/8" NPT on your manifold or plumbing fitting
  • Check the amp rating on your current switch label before replacing
  • Inspect the switch port and surrounding plumbing for corrosion or mineral buildup before installation
  • Confirm error codes on your spa (HH, ICE, OH) are pressure-switch-related and not a flow switch, temp sensor, or hi-limit issue

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