We hope this helps you cure bubbles coming out of your pool return jets! Remember, air in your pump system likely means there's an issue at one of three places: the skimmer, your pump or your unions. And if you need more help with pool maintenance, grab our free Pool Care Cheat Sheet at

Also check for your automatic pool cleaner hose if its crack/hole. Check the pressure gage/relief valve above the filter for loose, broken oring, crack near stem. Check the valve handle regulator if its leaning more than 45. Check also the drain plug o ring from pump. I have a first hand experience with the above problem so I am relating it to you, took me a long time to find it.

Thank you, just went around suction and discharge side and tighten - no more bubbles 👍👍 🇨🇦 more quite sand filter - no more sound of a creek.

If you have a salt water chlorinator, the byproduct of the chlorinator is gas/air. Troubleshooted this issue for some time, turned off my chlorinator briefly and the issue stopped. All other advice covered in this video is accurate.

Check “Jandy” valves at suction side, they can be sucking air through valve stem or lid “O” rings.

The Best advice as usual. Thanks SU!!!!

Thank you mate. Just solved my problem.

what if the bubbles are only coming from one of the jets?

Is cavitation from the impeller a thing? Could an unbalanced impeller cause bubbles?

I noticed air blowing out of the jets, told my pool guy and he finally told me he turned the vacuum up so it would go up the walls. Now my skimmer isn't pulling water in and the amount of air blowing out is crazy. He said it is fine but I disagree. Any thoughts? Unfortunately I don't know how to turn the vac back down (I have only been a pool owner for a year so please no one blast me for not knowing). Thanks

Would I get air bubbles if I drained my pool and refilled it. Will it stop after running for a few.

I've just got a saltwater pool. My brother in law has had his for years. He only puts salt and a small bag of shock every once in awhile. And his pool seems to do great. Can you use only salt and no other chemicals?? I've been doing the same as him and when I test it it stays pretty close to the norm's. Was just asking your thoughts. Thanks great videos

[smelker]

Its always a problem on the sucktion side of the pump that's creates bubbles..

[newbyk]

How do you get the air out once you fix the problem? Is there a way to ‘burp’ it?

[halehtoofanian]

sometime it is something very simple, like plugged filter in your universal wall connector that is hidden and can not be seen till you unplug it,

Whenever I first turn the pump for the day (usually I turn the pump on and off twice in any given day) bubbles emerge from the return jest at first (for about 10 or 20 seconds), but then -- after 10 or 20 seconds -- the bubbles subsided and disappear. Is that normal?

I have crackling in the diverter valve. It's in all positions. The bolts and nuts are tight. Is that an indication of a leaky valve seal?
Also, my pump was off for 2 days. When I went out to turn it on, the water was perfectly clear. I was surprised! I turned the pump on and a few hours later I had algae all over the bottom in the dips... All the chemicals are balanced. I have a feeling the sand is contaminated.
