Introduction
If you’ve noticed your hot tub making strange noises, uneven water flow, or if the jets aren’t working properly, trapped air might be the culprit. Purging air from your hot tub pump is a straightforward task that ensures your system runs smoothly. In this guide, we’ll show you how to safely remove air from your hot tub pump step by step, troubleshoot common issues, and keep your hot tub in top shape for relaxing dips.
Why Is It Important to Purge Air from Your Hot Tub Pump?
Air trapped inside the pump can cause loud noises, reduce water circulation, and even damage the pump over time. Properly purging air helps maintain optimal water flow, improves jet performance, and extends the lifespan of your equipment. Regular maintenance also prevents costly repairs and keeps your hot tub ready for use whenever you want to relax.

Step-by-Step Guide to Purge Air from Hot Tub Pump
Step 1: Turn Off the Power
Before you begin, **turn off the hot tub** and disconnect it from the power source. This is crucial for safety and prevents accidental starting of the pump during maintenance.

Tip: Always consult your hot tub’s manual for specific safety instructions related to your model.
Step 2: Drain or Lower Water Level (if needed)
In some cases, it’s best to lower the water level slightly below the pump inlet. This reduces water pressure and makes it easier to purge air. Check your manual to see if this step applies to your model.
Tip: Use the drain valve or siphon method to carefully lower water levels without causing damage.
Step 3: Open the Pump Access Panel
Locate the pump and remove the access panel or cover. This exposes the pump and filter area, giving you access to the pump inlet and outlet.
Note: Be gentle to avoid damaging any clips or seals.
Step 4: Check for Air Bleed Screws or Vents
Many hot tubs have an air bleed screw or vent valve near the pump or filter. If your model has one, loosen or open it slightly to allow air to escape.
Tip: Use a wrench or your fingers to turn the screw gently. Be careful not to overtighten when closing it later.
Step 5: Turn On the Hot Tub Power
Reconnect the power and turn on the hot tub. Set the jets to high or maximum flow to encourage air movement. Watch for bubbles escaping from the vent or bleed screw.
Note: Do not leave the hot tub unattended during this process.
Step 6: Observe and Burb Air Out
As the pump runs, you should see or hear air escaping as bubbles. Continue running the pump until persistent bubbles stop, indicating most of the air has been purged.
Tip: If your model has a manual air vent, keep it open until bubbles diminish.
Step 7: Close the Bleed Screw or Vent
Once the air has been expelled, tighten the bleed screw or close the vent securely. Make sure there are no leaks.
Tip: Check for any water leaks and ensure all connections are tight.
Step 8: Restore Water Level and Replace Cover
If you lowered the water level, refill the hot tub to the proper level. Replace the access panel or cover securely.
Tip: Use a garden hose for refilling, and check the water level regularly during this process.
Step 9: Turn Off and Restart the Pump
Turn off the pump, then turn it back on to verify that the air has been successfully purged. Listen for smooth operation and check for any unusual noises.
Tip: Run the jets for a few minutes to ensure water flows freely and air is fully expelled.
Practical Tips for Effective Purging
- Regular maintenance: Purge air periodically to prevent buildup, especially after cleaning or draining.
- Be gentle: Avoid forcing screws or parts, as damage can lead to leaks or further issues.
- Use the manual: Always refer to your hot tub’s manual for specific instructions related to your model.
- Monitor performance: Keep an eye on jet strength and noise levels after purging.
Troubleshooting Common Issues
Air Won’t Fully Escape
If air remains trapped after following the steps, check for leaks or cracks in the pump, hoses, or valves. Tighten all fittings and consider replacing damaged parts.
Jets Still Not Working Properly
Ensure there’s enough water in the tub. Low water levels can cause air pockets and reduce jet performance. Also, verify that the pump is primed correctly.
Persistent Noise or Vibration
Excess air can cause noise. If noise persists after purging, inspect for obstructions or worn pump parts. Seek professional help if necessary.
Conclusion
Purging air from your hot tub pump is a simple yet important maintenance step. It helps keep your hot tub functioning smoothly, prolongs the life of the pump, and ensures you enjoy relaxing, bubbly sessions. Regularly check and purge the system as needed, especially after draining or cleaning, to keep everything working perfectly. With these easy steps, you’ll be able to troubleshoot and resolve air-related issues confidently, making your hot tub experience even more enjoyable.
