10 Easy Steps on How to Fix Hot Tub Jets Blowing Out

Step 1. Inspect the Jets for Debris

The first step is to inspect the jets for any debris that may have been caught in them, such as leaves or other objects. If you see something blocking the jet, use tweezers or pliers to remove it. Be careful not to damage the jets as you remove objects.

Step 2. Clean Out the Jets

Using a Cleaning Solution

Next, clean out the jets using a cleaning solution and a brush. Make sure to get into all of the nooks and crannies to ensure they are completely clear before moving on. If you have trouble removing debris, you can also use a vacuum to suck it out. It will help to ensure that all stubborn clogs are removed.

Step 3. Check for Airflow Problems

Once the jets have been cleaned out, check to see if there is an airflow problem due to clogged vents or filters. Make sure these areas are free from obstruction and replace any filters that need replacing. You can also use a pipe cleaner to clear out any tight spots.

Step 4. Clean the Filter

Your hot tub filter should also be cleaned regularly to prevent blockage from occurring in the jets. Make sure that all particles are removed, and then reinstall it into your hot tub. Use a solution of vinegar and baking soda to clean the filter.

Step 5. Check Plumbing Connections

You should also check any plumbing connections leading to the jetted tubs to make sure there are no leaks or other issues affecting how water flows through them. Tighten any loose connections and replace any damaged parts. You can use thread sealant or Teflon tape on pipes to ensure a tight fit.

Step 6. Replace Damaged Parts

If you find any parts of the jet system that are damaged or worn out, it is important to replace them as soon as possible to prevent further problems down the line. This could include anything from gaskets to seals or even the jets themselves.

Step 7. Check for Power Problems

To Check for Power Problems

If your hot tub jets are still blowing out after all of these steps, you may need to check for power problems. Ensure the circuit breaker is not tripped and the wires are properly connected and secure. You may also need to replace a fuse or reset an overload switch if necessary.

Step 8. Clean the Tub

After completing all of these steps, it is important to give your hot tub a thorough cleaning to ensure that no debris is left behind in any areas where it could cause further blockage issues down the line. Use a mild cleaner and scrubbing brush to gently but thoroughly clean all surfaces of your hot tub. It will also help to give it a good rinse afterward.

Step 9. Test the Jets

Once all these steps have been completed, it is time to test your hot tub jets and ensure they are in working order again. Fill up the hot tub with water and turn on the jets. They should now be operating correctly without any blockages or airflow problems.

Step 10. Enjoy!

By following these ten simple steps, you can easily fix any issues that may be causing your hot tub jets to blow out. Don’t hesitate to call a professional if you need help, but with these tips, you should be able to fix your jets yourself. Have fun, and stay safe!

5 Additional Tips and Tricks

  1. Make sure that the pump is running correctly. Check the pump to ensure it has enough water and that all connections are secure. If the pump isn’t working properly, it may cause air bubbles in the jet line and make the jets blow out water.
  2. Clean the filter regularly to ensure maximum efficiency of your hot tub jets. A dirty filter can decrease water pressure, which can cause the jets to blow out water.
  3. Check the O-rings and gaskets around the jets to make sure they’re not cracked or damaged. If these seals are weak or damaged, they could be allowing air into the line and causing air bubbles in the jet line.
  4. Make sure the jets are not clogged with debris or algae. Clogs can cause water pressure to drop, resulting in your hot tub jets blowing out the water.
  5. If none of these troubleshooting steps work, you may need to replace the jets or other components of the hot tub system.

With a few simple troubleshooting steps, you can easily fix hot tub jets blowing out the water. If the issue persists or you need professional help to diagnose and repair any of these issues, it’s best to contact a qualified technician.

5 Things You Should Avoid

  1. Don’t attempt to fix the jets by yourself unless you are a certified spa professional.
  2. Don’t use any kind of cleaner on your jets that wasn’t specifically designed for hot tubs or spas.
  3. Avoid trying to adjust the position of the jet itself, as this can cause further damage to the system and possibly void your warranty.
  4. Do not attempt to add any type of lube or other chemicals to get the jets working again, as they can corrode and damage the internal components of the jets themselves.
  5. Never try to force open jammed Jets, as this could cause permanent damage. If there is an obstruction in front of it, remove all debris before turning it back on.

If you are having trouble with your hot tub jets, it is best to contact a professional to help get them functioning correctly again! With the right knowledge and tools, they can quickly diagnose the issue and resolve any underlying problems. This will ensure that your hot tub remains in top condition for many years to come!

Why Do Hot Tubs Have Blowers?

Hot tubs are equipped with blowers because these air pumps help to circulate the water and create a relaxing spa-like experience. The jets in the hot tub blow out air and water, creating an invigorating massage-like sensation on your skin and helping to relax tight muscles.

Keep the Temperature Consistent

In addition to providing this soothing feeling, the hot tub blower also helps keep the temperature consistent within your hot tub as well as helps to reduce energy usage. So not only does it provide a great massage effect, but it can help save you money!


If you have a hot tub or spa with jets that are blowing out, there are three potential causes and solutions. First, make sure the pump is primed if it has lost its prime, which can happen if the power is off for a while or if too much air gets into the system. Second, check that there aren’t any leaks in the hoses leading to the jets.

Third, clean the filters to remove any debris that might be blocking water flow. With just a little troubleshooting, you should be able to get your jets working again in no time!
