When Should You Replace Your Hot Tub Jets?

Before diving into the replacement process, let’s cover when it’s best to replace your hot tub jets. Here are the most common signs it’s time for a new set:

  • No water flow: If no water is coming out of the jet or the flow is significantly weaker than usual, the jet might be clogged or damaged.
  • Cracked or broken jets: If your jets are visibly damaged—cracked, chipped, or broken—it’s time for a replacement.
  • Inconsistent jet pressure: When some jets are functioning while others aren’t, it could be due to internal issues or damaged jets.
  • Aging jets: Over time, the rubber seals or internal components of jets can wear down, causing reduced performance.

If you’re experiencing any of these issues, replacing your jets could help restore the quality and performance of your hot tub.

Step-by-Step Guide to Replacing Hot Tub Jets

1. Turn Off the Power and Drain the Hot Tub

Safety is always the first priority. Before performing any maintenance, turn off the hot tub’s power at the breaker to prevent electrical hazards. Then, drain the hot tub water using the appropriate drainage method.

Draining the water will give you easy access to the jets and ensure that no water flows during the replacement process.

2. Identify the Type of Jet You’re Replacing

Hot tubs come with various jet styles, including directional, rotary, and air jets. Identifying the type of jet you need to replace will help you find the right replacement. If you’re unsure, refer to your hot tub’s manual or ask your hot tub retailer for assistance.

3. Remove the Old Jet

Once the power is off and the hot tub is drained, it’s time to remove the old jet. Most jets can be removed by twisting them counterclockwise. If the jet is difficult to remove, use pliers or a special jet removal tool.

  • Grip the outer ring of the jet.
  • Twist the jet counterclockwise to loosen it.
  • Pull the jet gently from its housing.

If the jet is stuck, you can tap it lightly with a rubber mallet to loosen it.

4. Install the New Jet

Take your new replacement jet and insert it into the jet housing. Align it properly and ensure the rubber seals are intact to prevent leaks. Once in place, twist the jet clockwise to secure it into the housing.

Be careful not to overtighten the jet, as this could damage the housing or the seal.

5. Test the New Jet

Once the new jet is installed, turn the power back on and refill the hot tub with water. Turn on the jets to ensure they’re functioning properly. You should see strong water flow with no leaks.

If the jet is working as expected, your replacement is complete. If not, double-check the installation for any loose connections or improper seals.

Additional Maintenance Tips

  • Regular Cleaning: Clean your hot tub jets every few months to avoid mineral buildup. Use a hot tub-safe cleaner to keep the jets running smoothly.
  • Check for Leaks: After installing the new jets, inspect the area around the jets for any water leaks. If you find any, ensure the jets are properly tightened and the seals are intact.
  • Consult a Professional: If you’re unsure about the replacement process or the issue seems to be more than just the jet, don’t hesitate to reach out to a professional hot tub technician for assistance.
