Hot Tub Air Lock: What Long Island Hot Tub Owners Need to Know
If your hot tub jets aren’t working after a drain, refill, or service visit, you may be dealing with a hot tub air lock. This is one of the most common issues we see when servicing hot tubs across Long Island, especially after seasonal maintenance or water changes. The good news? In many cases, it’s easy to fix — as long as you know what to look for.
What Is a Hot Tub Air Lock?
A hot tub air lock happens when air gets trapped inside the plumbing lines or pump, preventing water from circulating properly. This usually occurs after draining your spa for cleaning, winterization, or repairs. When the tub is refilled, air can remain trapped instead of being pushed out by water.
When this happens, your pump may run, but the jets won’t produce normal water flow — or may not work at all. Left unresolved, an air lock can cause overheating and premature pump failure, which is a costly repair many Long Island homeowners want to avoid.
Common Signs of an Air Lock
Long Island hot tub owners often call us when they notice:
- Jets not pushing water or only blowing air
- Gurgling sounds from the plumbing
- A pump that sounds like it’s running but no circulation
- Heater or flow-related error messages
If this happens right after a refill, an air lock is very likely the cause.
How to Fix a Hot Tub Air Lock (DIY Steps)
- “Burp” the Hot Tub Jets
This is the simplest method and works surprisingly well.
- Set the jets to low speed for 10–20 seconds
- Switch to high speed for another 10–20 seconds
- Repeat this process several times
This helps force trapped air out through the jets and allows water to fully prime the pump.
- Bleed the Air From the Pump
If burping doesn’t work, you may need to release air directly from the pump.
- Turn off power at the GFCI breaker
- Open the cabinet to access the pump
- Slightly loosen the bleeder valve or pump union
- Listen for air escaping
- Tighten once water begins flowing steadily
Once power is restored, the jets should resume normal operation.
Extra Tips for Long Island Hot Tub Owners
- Always refill your hot tub through the filter compartment when possible — this helps prevent air locks
- Make sure the water level is above the skimmer
- Remove or clean filters during troubleshooting
- Never run a pump dry for extended periods
Because Long Island winters and seasonal use often require draining and refilling, air locks are more common here than many owners realize.
