Fixing An Airlock Like A Pro
Dealing with Hot Tub Air Locks: Quick Fixes and Preventive Measures
Introduction: Have you ever eagerly anticipated a relaxing soak in your hot tub, only to be disappointed when the jets fail to deliver that invigorating experience? Is your local hot tub store is closed or just too far away, there’s no need to panic. In this guide, I’ll walk you through a simple solution to fix airlocks in your hot tub, saving you the hassle and expense of a service call.
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 Process: If your hot tub has diverters, ensure they’re fully open. Depending on your hot tub model, the filter might either un-thread or be attached to a standpipe. If there’s a standpipe, you may also be able to remove that as well. 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 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: In case 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.
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 slowly 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.
Expert Tip: 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.
Conclusion: Dealing with airlocks in your hot tub doesn’t have to be a daunting task. By following these simple steps and precautions, you can quickly fix the issue and enjoy the rejuvenating experience your hot tub was meant to provide. Remember, prevention is the best cure – always fill your hot tub through the filter compartment to minimize the chances of encountering airlocks in the first place.
