What Causes an Air Lock in Hot Tub?

A few different things can cause an air lock in your hot tub. One of the most common causes is when the water level in your tub gets too low. When the water level drops, it can cause the pump to suck in air, which will then create an airlock. Another common cause of airlocks is when the filter is dirty or clogged. A dirty or clogged filter can restrict the flow of water, which can also cause an airlock.

Additionally, if there is a leak in your hot tub, that can also cause an airlock. The other main cause of airlocks is when the jets are turned on too high. When the jets are turned on too high, it can create a suction that will pull the air into the system, which will then cause an airlock. Lastly, if your hot tub is not vented properly, that can also cause an airlock.

Why It’s Important to Fix an Air Lock

If you don’t fix an airlock in your hot tub, it can cause several problems. First, it can cause your hot tub to overheat. When the airlock prevents the water from circulating properly, it can cause it to overheat. Additionally, an airlock can cause your hot tub to run less efficiently. If the water isn’t circulating properly, it can’t be heated properly.

Another problem that an airlock can cause is that it can cause your hot tub to become noisy. The water isn’t circulating properly can create a banging noise. Lastly, an airlock can shorten the life of your hot tub pump. If the water isn’t circulating properly, it can cause the pump to overwork, which can shorten its life.

Some Easy Ways How to Fix Air Lock in Hot Tub

1. Locate the Airlock

The first step is to determine where the airlock is in your hot tub. An airlock can occur in different parts of the system. The most common places are in the pipes, the pump, or the jets. To locate the airlock, turn off the power to your hot tub. Then, remove the cover and take a look inside. If you see any bubbles or foam, that is a sign of an airlock. Next, try to determine where the bubbles are coming from. If you see bubbles coming from the jets, then the airlock is likely in the pipes. If you see bubbles coming from the pump, then the airlock is likely in the pump.

2. Check the Water Level

One of the most common causes of airlocks is when the water level in your tub gets too low. When the water level drops, it can cause the pump to suck in air, which will then create an airlock. To prevent this, it’s important to check the water level in your tub regularly. The water level should be at least halfway up the skimmer basket. If the water level is lower than that, you will need to add more water to your tub. To do this, you can use a garden hose. If you don’t have a garden hose, you can use a bucket to add water to your tub slowly.

3. Clean or Replace the Filter

Another common cause of airlocks is when the filter is dirty or clogged. A dirty or clogged filter can restrict the flow of water, which can also cause an airlock. Cleaning or replacing your filter is important to prevent this from happening. Most filters should be replaced every three months. However, if you have many people using your hot tub, you may need to replace it more often.

If you notice that your filter is dirty, you can clean it with a hose and some filter cleaner. First, remove the filter from the hot tub and then rinse it with a hose. Next, soak the filter in a bucket of filter cleaner for about 15 minutes. After that, rinse the filter again and put it back in the hot tub. Avoid using a pressure washer to clean your filter, as it can damage it.

4. Check for Leaks

If there is a leak in your hot tub, that can also cause an airlock. The most common place for leaks is in the pipes. To check for leaks, first, make sure that all the valves are turned off. Then, turn on the pump and see if any water is coming out of the pipes. If there is water coming out, then you have a leak. To fix a leak, you will need to replace the damaged pipe. You can usually find replacement pipes at your local hardware store. If you cannot find a replacement pipe, you can try patching the leak with a rubber patch.

Make Sure That All the Valves Are Turned Off

5. Vent the Hot Tub

If you have determined that the airlock is in the hot tub itself, you can try venting the hot tub. This will require you to open the hot tub cover and locate the air vent. Once you have found the air vent, please open it and allow the hot tub to vent for a few minutes. After a few minutes, close the air vent and see if the problem has been resolved. You may need to call a professional for assistance if the problem persists. Avoid using the hot tub until the problem has been resolved.

6. Bleed the Lines

You can try bleeding the lines if the airlock is in the pipes. This fairly simple process can be done with a few tools. First, you will need to locate the bleed valve. The bleed valve is usually located.

On the skimmer basket or on the filter canister. Once you have found the bleed valve, use a flathead screwdriver to open it slightly. Then, use a garden hose to fill the tub with water slowly. Make sure that the valve is open the entire time. The air should eventually bleed out of the system, and the water should start to flow freely. Avoid overfilling the tub while bleeding the lines.

7. Prime the Pump

You can try priming the pump if the airlock is in the pump. This process will require you to have a bucket of water and a garden hose. First, make sure that the pump is turned off. Then, attach the garden hose to the inlet valve and place the other end of the hose into the bucket of water.

Please turn on the pump and let it run until water starts flowing from the garden hose. Once water is flowing, turn off the pump and disconnect the hose. This process should get rid of any air that was in the pump.

8. Use a Hot Tub Pump

If the airlock is still unresolved, you can try using a hot tub pump. This process will create suction and help to remove the airlock. First, you must place the hot tub pump in the water. Make sure that the pump is completely submerged. Next, you will need to turn on the pump and let it run for a few minutes. After a few minutes, you can turn off the pump and see if the airlock has been removed. If the airlock is still present, you can repeat this process until the airlock has been completely removed.

9. Call a Professional

If you have tried all of the above methods and the airlock is still present, you may need to call a professional. A professional can quickly and easily identify the problem and resolve it. They may need to replace a part or two, but they should be able to get your hot tub up and running in no time.

How Much Does It Cost to Fix an Air Lock in Hot Tub?

The cost of fixing an airlock in a hot tub can vary depending on the cause of the problem. For example, if you leak, you may need to replace a pipe, which can cost around $100. If the problem is with the pump, you may need to replace the entire pump, which can cost around $200. If you need to call a professional, they may charge an hourly rate ranging from $50 to $100 per hour.
