Fortunately, there are some things you can do to fix this problem and get your hot tub back to working order.

How to Fix Hot Tub Jets Blowing Out

This article will discuss some common causes of jet blowing and explain how to fix hot tub jets blowing out. We will also provide tips for keeping your jets in good condition so that this does not become a recurring issue. So, read on for helpful information, whether you are dealing with a blown jet for the first time or just want to prevent it from happening again.

Summary: If your hot tub jets are blowing out, there are several steps you can take to try and resolve the issue. First, check for any clogs in the intake hose. Next, make sure the air pressure is set correctly; too much air can cause the jets to blow out water.

15 Steps on How to Fix Hot Tub Jets Blowing Out

Step 1: Gather Necessary Tools and Materials

To fix hot tub jets blowing out, you will need the following tools and materials:

  • Screwdriver or wrench set
  • Replacement jet parts (if needed)
  • Plunger
  • Teflon tape or plumber’s tape
  • Gasket lubricant or plumber’s grease
  • Hot tub cleaner or vinegar solution
  • Clean, lint-free cloth
  • Garden hose with a high-pressure nozzle
  • Soft-bristle brush

Step 2: Ensure Safety

Before starting the repair process, turn off the hot tub and disconnect it from the power source to ensure your safety while working on the jets.

Step 3: Inspect the Hot Tub Jets

Examine the jets for any visible damage, such as cracks, loose fittings, or broken components. If any damaged parts are found, make a note of them and order replacement parts as needed.

Step 4: Clean the Jets

Remove any debris or buildup from the jets using a soft-bristle brush and hot tub cleaner or a vinegar solution. For stubborn debris or mineral deposits, use a garden hose with a high-pressure nozzle to rinse the jets thoroughly. After cleaning, use a clean, lint-free cloth to wipe the jets dry.

Step 5: Remove the Jet Assembly

Using a screwdriver or wrench, remove the screws or bolts holding the jet assembly in place. Carefully remove the jet assembly from the hot tub, taking care not to damage any components.

Step 6: Inspect the Jet Assembly Components

Examine the jet assembly components for any signs of damage, wear, or deterioration. If any damaged or worn parts are found, replace them with the appropriate replacement parts.

Step 7: Clean the Jet Assembly Components

Clean the jet assembly components using a soft-bristle brush and hot tub cleaner or a vinegar solution. Rinse the components thoroughly with water and dry them with a clean, lint-free cloth.

Step 8: Lubricate the Jet Assembly Components

Apply a thin layer of gasket lubricant or plumber’s grease to the O-rings, gaskets, and any other moving parts within the jet assembly. This will help ensure smooth operation and prevent leaks.

Step 9: Reassemble the Jet Assembly

Reassemble the jet assembly, making sure to replace any damaged or worn components. Secure the assembly with the screws or bolts that were removed earlier.

Step 10: Apply Teflon Tape or Plumber’s Tape

Wrap a layer of Teflon tape or plumber’s tape around the threads of the jet assembly fittings to help create a watertight seal and prevent leaks.

Step 11: Reinstall the Jet Assembly

Carefully reinstall the jet assembly in the hot tub, making sure that the fittings are properly aligned and seated. Tighten the screws or bolts to secure the assembly in place.

Step 12: Check for Leaks

Reconnect the power source and turn on the hot tub. Allow the water to circulate through the jets, and inspect the jet assembly and fittings for any leaks. If leaks are present, turn off the hot tub, disconnect the power source, and repeat the necessary steps to correct the issue.

Step 13: Clear Any Air Locks

If the jets are still blowing out after reinstalling the jet assembly, there may be an air lock in the plumbing. To clear the air lock, use a plunger to create a pressure differential in the plumbing system. Place the plunger over the jet opening and push down firmly, then quickly pull up to force water through the jet and dislodge any trapped air.

Step 14: Adjust the Jet Pressure

If the jets are still blowing out after clearing any air locks, the jet pressure may be too high. Adjust the pressure control on the hot tub to lower the water flow and reduce the force of the jets. This can be done using a control panel, knob, or valve, depending on the specific hot tub model.

Step 15: Inspect the Pump and Filter

If the problem persists, inspect the hot tub’s pump and filter for any signs of damage, clogs, or improper functioning. Clean or replace any dirty or clogged filters, and repair or replace any damaged pump components as needed.

Troubleshooting Hot Tub Jets Blowing Out

1. Check the water level. If the water level is too low, the jets may not be getting enough water to operate correctly and may start blowing out.

2. Check the filters. If the filters are clogged, it will restrict the amount of water passing through the jets and create back pressure. Clean or replace the filters as necessary.

3. Clean or replace the jets. If the jets are clogged or dirty, they may not be able to push enough water through the tub to create a good flow. Clean them out with a jet cleaner or replace them if they are too clogged to clean.

4. Check the pump. If the pump is not working correctly, it may not be pushing enough water through the jets. Check to make sure the pump is plugged in and turned on. If the pump is not working, you may need to call a professional to fix it.

5. Clean out the jets. If the jets are clogged, they will not be able to push water through them, which will cause them to blow out. Use a pipe cleaner or a small brush to clean out the jets. If your hot tub’s jets are constantly blowing out, something may be blocking them. In most cases, the blockage is caused by dirt or debris collected in the jets.

6. Check the valves. If the valves are not opening or closing correctly, it may not be allowing enough water to pass through the jets. Check the valves and make sure they are working properly.

7. Adjust the water pressure. If the water pressure is too high, it can cause the jets to blow out. Reduce the water pressure by turning the pressure regulator valve counterclockwise.

Can Hot Tub Jets Get Clogged?

Yes, hot tub jets can get clogged. Hot tubs are often used as a way to relax and de-stress, but this activity can also lead to clogging of the jet system. This is because suds created by the jets travel up the drain and into the sink or toilet, where they form grease and sediment that becomes difficult to remove. In extreme cases, this buildup may even cause flooding in your home or business if not addressed promptly.

Do Hot Tub Pumps Have a Reset Button?

A number of factors can affect the functionality of a hot tub pump. Assuming that you are asking about the reset button on a typical hot tub pump, the answer is that it is typically not located on the pump itself, but rather on a controller or control box that is connected to the pump. If you need to reset the pump, you would need to access and reset the controller or control box. Sorry for not being more specific!


Blowing out jets is often a result of incorrect water chemistry. For example, when the pH level and alkalinity are not in balance, it can cause calcium deposits to form on the jet nozzles. This blockage will then force the water to flow out uncontrollably, resulting in blown jets. To fix this issue, you need to adjust your water chemistry and clean the calcium deposits from the jet nozzles. 

If you are experiencing this issue with your hot tub jets, a simple solution should take care of the problem. Follow these steps to fix the jets and get back to enjoying your hot tub! Thanks for reading our blog post on how to fix hot tub jets blowing out.
