Are you experiencing issues with your hot tub, like strange noises or non-functional jets?
These are common signs of a hot tub airlock. In this guide, we’ll show you how to recognize these symptoms and fix the problem quickly so you can enjoy your hot tub again.
Key Takeaways
- Look out for unusual noises and jet malfunctions as early signs of a hot tub airlock.
- Prevent air locks by using correct filling techniques, bleeding the pump, and activating priming mode.
- Fix air locks by methods like burping jets, releasing air from the pump, and running the pumps; call a professional if issues persist.
Recognizing Hot Tub Air Lock Symptoms
Early detection of hot tub air lock signs can save significant hassle. One of the first indications is unusual noises coming from your hot tub’s pump. These sounds, often described as humming or hissing, are a telltale sign that air is trapped in the system, disrupting water flow. Another strong indicator of an airlock is the malfunctioning of hot tub jets when powered on.
Air in the plumbing lines severely affects the performance of the hot tub jets, leading to inadequate water flow and inconsistent heater operation. This can make your hot tub experience far from enjoyable. Identifying these symptoms early helps maintain hot tub efficiency and prevent extensive repairs.
Causes of Hot Tub Air Locks
The most common cause is air getting trapped in the plumbing lines. This usually occurs during the draining and refilling process. Draining water allows air to be replaced in the plumbing and pump, potentially causing blockages.
Airlocks frequently occur after the hot tub is drained and refilled. Air fills the empty spaces in the plumbing and pumps as water drains out, creating conditions for an airlock upon refilling. If not properly purged, this trapped air prevents water from circulating correctly, causing your hot tub to malfunction.
Preventative Measures for Hot Tub Air Locks
Taking the right steps during maintenance can effectively prevent air locks in your hot tub. Start by using proper filling techniques to minimize the risk of air becoming trapped in the plumbing lines. Next, bleed the pump to release any air that may have entered during the filling process. Finally, utilize your hot tub’s priming mode to ensure the system is completely free of air.
These practices are essential for maintaining smooth water circulation and ensuring your hot tub operates efficiently.
Let’s explore each of these preventative measures in greater detail.
Proper Filling Techniques
Proper filling techniques are one of the most effective ways to prevent air locks. Instead of placing the garden hose directly into the hot tub, insert it into the empty filter canister. This method helps eliminate trapped air by allowing water to flow through the system evenly and prevent air pockets from forming.
Correct filling techniques are essential for preventing air locks in your hot tub. Ensuring the water enters through the filter well creates a smoother path for the water to travel, reducing the risk of air getting trapped in the plumbing lines.
Bleeding the Pump
Bleeding the pump is another key step to prevent air locks. This process involves expelling trapped air from the pump after filling the hot tub with water. First, turn off or lower the heater’s temperature to prevent overheating, then use the bleed valve to release trapped air.
Avoid over-tightening the bleed valve or using tools that might damage it. If burping the system (running jets on and off) fails, use a garden hose to force water through the plumbing lines to purge the remaining air.
Using Priming Mode
Engaging the hot tub’s priming mode effectively expels trapped air. Priming mode circulates water through the plumbing lines, removing air pockets and causing an airlock.
Activating priming mode ensures smooth water movement, maintaining optimal hot tub functions.
Fixing a Hot Tub Air Lock
If you’re already dealing with a hot tub airlock, don’t worry. Fixing it is possible with a few straightforward steps. First, turn off the hot tub and disconnect the power supply. Safety first! Next, check the water level in your hot tub to ensure it’s adequate for proper function.
Promptly clearing an air lock prevents significant damage and ensures smooth pump and plumbing function. While fixing the airlock, look for water running out of the plumbing, indicating trapped air is expelled, and proper circulation is restored.
Here are some specific methods to fix a hot tub airlock.
Burping the Jets
A common method to fix an airlock is burping the jets. Initially, set the jets to low for 10-20 seconds. After that, switch to high for another 10-20 seconds and repeat this cycle three to four times. This process purges air from the jets, allowing water to flow freely again.
While burping the jets, observe the number of air bubbles coming out. This indicates that trapped air is being released. If the airlock persists after three or four attempts, try other methods.
Releasing Air from the Pump
Releasing air from the pump is another method for addressing an airlock. Use the bleeder valve on your pump to expel the air trapped efficiently. Loosen the barrel union nut until air escapes, then re-tighten it.
Regular checks and maintenance of your pump’s union nut ensure easy access to release trapped air. Once the air is released and water flows, the airlock is resolved.
Running the Pumps
Running the pumps effectively purges air from the hot tub system. Start by running the pumps at low speed, then switch to high speed. Ensure that water comes from all jets within two minutes to confirm that the air has been purged.
If pumps are not primed correctly after two attempts, restart the priming process. Ensure water circulates through all jets within 20 seconds to confirm the hot tub is free from air lock.
