So my pool was just completed a few months ago and after it was all set up I would get little bubbles coming out of the returns in the pool. Without the pool builder coming to the house to see my concerns he mentioned over the phone that it is normal because I have a salt cell. I did my homework and saw that this is possible so I let it go.
So my auto-fill is almost always on (trickling) so at one point I had turned it off and a few days later the water was down a few inches from where it should be. From what I read on the internet it could be evaporation so I tried the bucket test for two days. Two days later it seemed like it passed the bucket test. I turned on the auto-fill again and let it fill up however it does not shut off, just goes to a slow trickle once it gets higher with the float. So lately I have been messing with the float adjusting it down so it pushes up the float higher to shut it off. That does the trick but then the water goes down much further than it should because the float has been adjusted. Then I am adjusting it once again to fill the pool but again once it gets near full it will just trickle rather than shut off.
Now to the next part which is in the subject line. I can come out to the pool and at times (intermittent) it will have bubbles coming out of the returns. Everything I have read is if there are bubbles it is getting air from somewhere. Strange thing is that it does not always do this and it can be big or small bubbles at any given time.
A few weeks ago I cleaned the filter for the first time hoping this would solve the issue however all it did was clean the filter and the bubble are still present. The bubbles come and go with or without the salt cell being on. I will attach three videos I have taken and ask for your opinions on what you think may be going on.
I have already sent my PB an email yesterday morning and waiting on a reply. Again I mentioned this when the pool was opened for a few weeks and they said it was normal and did not even come back to check my concerns. After spending this much money on our backyard it needs to be right.
This was the first video I sent the PB. The salt cell was on at this time and he said it was normal:
Here was a video from a few weeks ago. The salt cell was NOT on as it was early in the morning when the vacuum was on:
Here is a video from this morning. Again the salt cell was not on and the vacuum was going:
Thanks to everyone from their comments.
I just started to think could the bubbles be entering from the pool sweeper as it does come to the surface sometimes and you hear it gulping air. That seems plausible to me for the air entering the system. Just something I thought about now.
