Will air bubbles burn up a motor if left for a long time?

[@Sal112350]

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.

Thanks! My weir door was the issue. Your video solved my problem!

[@brandonscarwash1493]

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.

Thanks for sharing!

[@leandroludvig7621]

Thank you mate. Just solved my problem.

[@daakrolb]

Cool. Out of curiosity, where was your air coming it??

[@johnweinisch8543]

[@jumpingisuseless4037]

I have a question. My sand filter has a leak right where you screw on the lid and the side of where the chlorinator is at. Could it be leaking there because I don't have pvc pipe going to the pool and it is weighing the tubing down this creating more pressure on that side of the lid?

[@kevinmello9149]

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

[@jakeschaeper535]

Same issue here

[@Ayame424]

Same issue. Any update?

[@Razorthedog]

It can be a hole inside of the pipe that comes out of that jet

[@taylean15]

Could just be the closest jet from your system and it only comes out of there before diverting to the other jet. Good way to know is to block the jet and see if the bubbles come out the other one

[@Sal112350]

When you turn off the pump and listen to filter if it has gurgling sound, chances are the the band clamp of the filter needs tighten, might be loose, use wrench to tighten it,, not hand tighten not enough. The gauge too on top need inspection if it has crack stem worn gasket loose, pump relief o ring might be broken. Check if weir is stack, check if hoses are broken, low water should be middle of skimmer port minimum. All of this I have encounter on bubble coming out of the return jet.

[@cgnieves1]

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

[@daakrolb]

I suspect mine air is coming in suction side. What are these valves you speak of?

[@daakrolb]

Ok I see- the valve on top my filter. So you mean… where the water enters the valve?

[@3vie5679]

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

[@brianbare6377]

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

[@SwimUniversity]

If you don't have any issues and your levels are normal, that's great. But one of the common problems is high pH. Check out our other video about Salt Water Pool Maintenance to see if you're ticking all the right boxes: kzbin.info/www/bejne/aKqaf6aJma5rZ5o

[@seasparrow7427]

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. Your thoughts and recommendations...

[@SwimUniversity]

If it's a sand filter, when was the last time you backwashed or changed your sand?

[@garagetalk]

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

[@halehtoofanian6822]

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,

[@waldtk3000]

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?

[@frankb.8376]

Odd situation (at least for me). I have a 3 line manifold going into my pump. A 3 way valve in from pump separating main drain (spa) to rest of pool. When I close the spa main drain, I get air bubbles and pressure actually drops. If I open it even half way, pressure RISES and bubbles go away. Closing Skimmer and /or vacuum valves do not cause bubbles to appear. Not sure where issue lies. Any help would be greatly appreciated.

[@smelker]

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

[@olivasaz]

What happens if cavitation only happens during certain pop-up cycles? for example my pump gets extreme cavitation only when certain cycles are on. the rest it runs perfectly quiet. I can't figure it out!!! help!!!!

[@newbyk]

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

[@Lockedo]

Firstly what’s the cause of the bubbles? If its in the pump that will natural blow out as time goes on until you clear the pump basket and let the air in. When you prime the pump if it needs to be primed fill it up as much as you can to reduce the bubbles. If it’s inside the filter itself the air will be at the top so there should be a bleeder vavlue you can open to bleed air and close it when water starts to spray out. If it’s another cause follow the video and see what happens and if it fixes anything . If you think you fixed it wait for around an hour and see if the return keys have less bubbles or no bubbles at all

[@teasjoe3814]

I turn on my pump and the water blows out the jets for a few seconds and then stops.. water pressure isn’t moving either stays on 0… didn’t have this protest year.. In ground 12ft pool… please help

[@daakrolb]

One of our pool guys was like “take the weirs off.” Told a story about one jamming shut, starving the pump…. I suppose checking the pool regularly would prevent this though.

[@jackismith1429]

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

[@Sal112350]

Those vacuum/skimmer valve have to be right or cavitation. Play first about 45 degree, adjust until no longer bubbles.

[@Rezolution01]

​@@Sal112350it's always the comment section that solves the problem lol. You are 100% correct, even if I don't understand the science behind it. I had my return/vacuum valve sending too much pressure to my vacuum. I adjusted it so that it wasn't overpressuring my vacuum and all the bubbles went away.

[@jamiewelch2595]

My bubbles are giant and only when I first start the pump then there are no air bubbles at all after the initial start up. Everything checks out OK as far as the 3 main causes. It only just started doing this a few days ago and I can't figure it out. Any other suggestions?

[@ianstover5474]

You probably have a seal where the pipes join together go bad. Pressure release on top of filter need to be in the proper locked position too.

[@user-zc8zx6jl5g]

When lubricating "O rings, don't apply lubricant as shown in video, as this will STRETCH the "O" ring and you will not get a positive seal. Pat or dabble it on, working it around the rubber seal. Thank you, great video

[@louisd95714]

I had air bubbles when I opened my above ground pool a few weeks back. It was driving me crazy. It turned out it was the actual eyeball that was causing the problem. Luckily, I had a spare, and the air bubble stopped as soon as replaced it.

[@SavageM]

How does a faulty eyeball cause air bubbles?

[@Sal112350]

@@SavageM you are right doesn't make sense. The most of my friend pool who called me about bubbles in their return jets turn out that they just hand tighten the band clamp which causes leak, you must use wrench. I just asks when did you clean the filter and check it with wrenches. The other is that quick release air, they don't last long plastic, buy metal brass stem cost more but less headache.

[@jax408]

Do I turn my pool off ? I can't fix it ?

[@Robplumber]

Do a cracked pipe cause it😮

[@shaggylocs232]

I fix it It keeps coming back my pool loves bubbles i guess

[@jonathanlaos4810]

Are air bubbles harmful to your pool ?

[@seasparrow7427]

No, but air in your pump will cause cavitation and reduce the life of your pump.

[@alohamark3025]

Here is one big no-no for pool users: my daughter decided she did not like the Kreepy Krauly vac inside the pool so she lifted it out of the pool. It sucked air that the pump returned to the pool through the first jet. Suffice it to say that this not only caused cavitation, but also destroyed a $1500 pump.

[@Sal112350]

This happen to me too, luckily I was there when my son did it and I teach him to remove it from the wall connector.

[@unkljj]

You have a very sensitive pool. 1500 in damage?
