Hot tub jets are a key feature for relaxation and hydrotherapy, but when they stop working properly, it can be frustrating. Whether your jets are weak, not working at all, or making unusual noises, there are usually simple fixes. In this guide, we’ll walk through the most common hot tub jet issues and how to fix them so you can get back to enjoying your soak.
1. Weak or No Water Flow
One of the most common problems with hot tub jets is weak or no water flow. This can happen for a variety of reasons, but here’s what to check:
- Clogged Filter: A dirty or clogged filter can restrict water flow to your jets. Remove the filter and clean it thoroughly, or replace it if it’s worn out.
- Low Water Level: If your water level is too low, the jets may not work properly. Make sure the water covers the jets completely and top it off if necessary.
- Air Lock: Air trapped in the plumbing system can prevent water from flowing through the jets. To fix this, turn off the hot tub, open the jets all the way, and turn the tub back on to allow the air to escape.
2. Jet Won’t Turn On or Off
If your jets won’t turn on or off, there could be an issue with the jet controls or diverter valve.
- Stuck Diverter Valve: The diverter valve controls the water flow to different areas of the hot tub. If the valve is stuck, it may need cleaning or lubrication. Make sure there’s no debris blocking the valve.
- Jet Control Malfunction: If the control knob for your jets is broken or not responding, you may need to replace it. Check the manufacturer’s instructions for how to replace the control knob.
3. Jets Making Noise
Unusual noises coming from your jets, such as squealing or rattling, can indicate a problem with the pump or air in the system.
- Air in the Jets: If you hear gurgling noises, there may be air trapped in the jets. As mentioned earlier, this can often be resolved by turning off the hot tub, opening the jets, and turning the tub back on to purge the air.
- Loose Jets: Sometimes, jets can become loose and rattle. Try tightening the jet face or replacing the jet if it’s damaged.
- Pump Issues: If the noise is coming from the pump, it could be a sign of a failing pump motor or debris caught in the impeller. In this case, it’s best to contact a professional for further inspection.
4. Jets Not Staying in Place
Hot tub jets are designed to be adjustable, but sometimes they can become loose and won’t stay in place. This is often caused by wear and tear over time.
- Check the Jet Face: Remove the jet and inspect the face for any damage or wear. If the plastic has deteriorated, you’ll need to replace the jet.
- Lubricate the Jet: Applying a small amount of silicone lubricant to the jet face can help it move more smoothly and stay in place.
5. Jets Clogged with Debris
Debris, such as dirt, oils, and small particles, can clog the jets and restrict water flow. This is a common issue, especially if the hot tub isn’t regularly cleaned.
- Clean the Jets: Remove the jets and soak them in a cleaning solution to remove any buildup. You can use a small brush to scrub away stubborn debris.
- Regular Maintenance: To prevent future clogs, regularly clean your hot tub and filter, and use a water clarifier to keep the water free of debris.
6. Broken or Worn Jets
Like any mechanical part, hot tub jets can wear out over time. If your jets are cracked, broken, or no longer functioning as they should, they’ll need to be replaced.
- Purchase Compatible Replacements: Make sure to buy replacement jets that are compatible with your hot tub model. Check the manufacturer’s instructions for the proper installation process.
- Replace the Jet: Most jets can be easily unscrewed or popped out and replaced with a new one. Make sure to turn off the hot tub before attempting to replace any parts.
Conclusion
Maintaining your hot tub jets doesn’t have to be difficult. By regularly cleaning your jets, monitoring water levels, and addressing any issues as they arise, you can ensure your jets continue to provide a relaxing and therapeutic experience. If you encounter a more serious issue that can’t be fixed with basic troubleshooting, don’t hesitate to contact a professional for assistance.
