How to Replace Spa Jets


A spa bathtub is unlike a regular bathtub in that it has jets set inside the walls that propel water out in a high-pressured stream. You can replace a spa jet that is malfunctioning or has ceased to work altogether, providing a replacement jet has been procured from a pool/spa-supply store or the dealership from where the spa was originally purchased. A few household tools are needed but no specialized equipment.

Things You'll Need

  • Phillips screwdriver or Torx screwdriver
  • Coffee mug
  • Adjustable wrench
  • Turn the spa bathtub's power switch to "Off" if it is not already set as such. Open the water-valve compartment lid -- typically, this is on a bottom edge of the spa bathtub but can also be at one end at the top depending on the manufacturer.

  • Rotate the water valves inside the compartment clockwise to stop the flow of water.

  • Remove the screws from the vented grille that covers the spa jet using a Phillips screwdriver or a Torx screwdriver depending on the manufacturer. Place the screws in a coffee mug to keep them from getting lost.

  • Pull the vented grill off and place it outside the spa bathtub. Place the jaws of an adjustable wrench around the spa jet where it meets the pipe inside the compartment. Adjust the wrench to grip the spa jet tightly.

  • Twist the wrench counterclockwise to loosen the spa jet from the pipe. Remove the wrench. Rotate the spa jet counterclockwise until it comes off the pipe. Set the spa jet aside.

  • Screw the replacement spa jet onto the pipe using a clockwise motion. Tighten the spa jet on the pipe using the wrench.

  • Place the vented grille back on the compartment. Reattach the screws. Rotate the water valves counterclockwise to restore the flow of water. Close the water-valve compartment lid.

Tips & Warnings

  • Wipe off tools made of metal with an oily cloth when done to keep them from getting rusted.
  • Some spa bathtubs will have screws on the water-valve compartment lid that require removal before water valves can be accessed.
