Next, you need to clean the jets properly. Remove all the debris or junk on them. They can be easily cleaned using a brush with hot tub cleaner products or any type of vinegar at home.

If the buildups are hard to clean up or any type of mineral deposits are visible, you should work with pressurized water force using a suitable garden hose setup. Once cleaned, you should wipe dry the jets as soon as possible using a fresh dry cloth.

Step #3: Dispel the Jet Assembly

At this point, you have to remove the jet assembly holding that with care. To remove that you can use a wrench and screwdriver whichever suits the setup.

Make sure to remove the jet assembly from the hot tub with extra care. You must not damage other components while removing the jet assembly.

Step #4: Examine and Clean the Assembly Components

In this phase, one should observe the components of the jet assembly. If there are any signs of junk, damage, wear and tear the affected parts or components should be removed and replaced.

In this case, you should try to use the proper tools and appropriate parts while swapping.

Then, clean the components cautiously. You can use a brush or cleaning cloth to apply the dedicated hot tub cleaner or vinegar solution on the target components.

Then you should submerge them into the water or rinse them thoroughly using a hose pipe. After the wash, dry each of the components with a fresh lint-free cloth immediately.

Step #5: Use Components lubrication

It is time to lubricate the moving parts of the jet assembly components. You can apply any good quality plumbers grease or gasket grease on them.

You must follow the guidelines provided and secure the jet assembly with the previously removed bolts and screws. If there are any damaged bolts it is better to replace them.

Once the jet is ready, you should cautiously install it in the hot tub. You must remain extra careful and you should check the fittings and placement of the jet assembly on the tub.

The alignment should be properly checked before tightening up the bolts and screws on the dedicated place. Always double-check the fittings if they are secured adequately or not.

Step #7: Usage of plumber’s or Teflon tape

Application of Teflon-based tape or plumber’s tape is always better to make the fittings tight and sealed.

A thin layer of such tape around the threads of jet assembly fittings can make the setup water sealed. Moreover, this initiative will prevent or decrease possible leakage sharply.

Step #8: Possible Leak inspection

Now, you should reconnect all the wires and power up the hot tub to check if that is up and running. Let the water flow through the hot tub and scan out if any water leakages are present.

Especially check the jet assembly and crucial fittings areas. If you find any leakage or other issues, you should unplug the power source and disassemble the problematic parts.

Here, you should take the necessary steps to solve the issues and repeat them if further required.

Step #9: Clearing the Air blockages

After the reinstallation, if the jets are blowing out then there should be a possible case of airlock in the plumbing. To remove the airlock you can use a plunger to make an air pressure difference in the plumbing system.

To use the plunger properly, you have to place the plunger over the opening of the jet and push it down. Then immediately pull up which will force the water to fill up the jet and unclog any trapped air in the process.

Step #10: Pressure Adjustment of the Jet

Sometimes the jet blowing keeps on going even after the air unclogging. After air clearing, if you see the same condition, it might be a cause of high jet pressure.

In this condition, you have to adjust the pressure control system of the hot tub. This will reduce the water flow and overall force of the operational jets. The blowing should be stopped or decreased after this adjustment.

You will find the adjustment facility in the control system knobs or any other type of switch or knobs, according to the hot tub design.

Step #11: Observing the Hot Tub’s filter and pump
