Preventing Airlocks

The key to avoiding airlocks in your hot tub lies in how you fill it. Always fill your hot tub through the filter compartment. When filling your hot tub, you aim to eliminate air from the pump and plumbing system by forcing water in and air out.

Filling Your Hot tub

If your hot tub has diverters, ensure they’re fully open. Depending on your hot tub model, the filter might either unthread or be placed over a standpipe and held on with a cap. If there is a  standpipe, you may also be able to remove that. Be cautious when removing it to avoid damaging it or your hot tub. With the filter removed, you should now have an open hole to insert the garden hose. Put your garden hose as far as possible without it getting stuck. If inserting the hose is not possible, placing the hose in the filter compartment will also suffice. As you fill the tub, ensure your hose will not come out of the compartment.

Addressing Airlocks

If you encounter an airlock, don’t fret. You can resolve it with a few simple steps and tools. A pair of large plumbers’ channel locks are your best friend for this task. Alternatively, a strap wrench can also be effective.

Locate The Jet Pump or Pumps

Identifying the Problem Pump

For hot tubs with multiple pumps, you must first determine which pump is causing the issue. If your hot tub has only one pump, skip to the next step. In a two-pump system, place your hand on a pump and press a jet button on the control pad. Feel for vibrations to identify the pump that’s running. Repeat this process with other pumps until you match each button to its respective pump.

Clearing the Airlock

With the problem pump identified, turn off the hot tub’s power and use the channel locks to loosen the large nut at the end of the pump in a counterclockwise direction. You’ll hear air escaping, followed by a small amount of water leakage. Re-tighten the nut, restore power to the hot tub, and test the pump. If the issue persists, don’t be discouraged; removing the airlock from the lines might take a few attempts.

Locate The Large Nut At The Pump

I do not recommend removing the small hose attached to the pump as they’re delicate and prone to damage, especially in colder conditions. Breaking this hose connection could lead to an expensive service call, which is certainly not covered by warranty.
