How To Quickly Fix a Hot Tub Air Lock

There is nothing more annoying than turning on your hot tub after you spent a great deal of time cleaning it and refilling it with fresh water than an air lock.

Unfortunately, this type of problem is quite common when you change the water on a hot tub, so knowing how to fix it is very important for every hot tub owner.

Luckily, there are different ways you can quickly fix an air lock in a hot tub so you can get back to enjoying your spa in no time flat. Today, let’s take a look at a couple of fixes that will clear that air problem in just a few short minutes.

What Is a Hot Tub Air Lock?

Before you can begin to fix an air lock in a hot tub, you need to understand what it is. In most cases, an air lock occurs when you drain your hot tub, clean it and then refill it. During that time that your hot tub sits without water, air can become trapped inside your hot tub. This air can prevent your hot tub jets from functioning and even damage your hot tub if you don’t repair it.

When an air lock happens, you will quickly notice the problem. You will turn on the jets and hear the motors running but you will see that no water is flowing through them as it should. That is because there is air trapped inside the plumbing preventing the water from flowing normally.

A hot tub air lock can vary in its severity based on the amount of air that has become trapped inside your hot tub. However, there are different methods you can try to fix this air lock yourself so you don’t have to call in outside help.

Let’s Pass That Gas

Aside from my silly puns, a hot tub air lock is serious business, and it is something that you need to look after right away. Luckily, in most cases, fixing a hot tub air lock isn’t too difficult and can also be fixed rather quickly. Let’s take a look at some quick fixes to get rid of that extra air trapped in your hot tub.

Burp That Baby

This first little trick is the easiest to do, and it can be done by anyone regardless of their technical experience.

  1. Turn down the heat. Before you do anything else, crank the temperature down so it doesn’t try to kick on while you are getting rid of that air.
  2. Open all the jets by turning each of the faceplates counterclockwise. Make sure every jet is opened completely.
  3. Turn on the jets of your spa and turn them to high. Once they are on high, allow them to run for 10-15 seconds.
  4. Repeat the previous step 3 times increasing the run time by 10-15 seconds each time.
  5. When you see air bubbling from the jets leave them running until all the air has been released.

This is by far the easiest way to get rid of that extra air in your hot tub, but unfortunately it won’t always work. If after three times you don’t see air coming from the jets STOP the burping procedure immediately.
