We have just recently had a saltwater gunite pool installed and are newbies. I have done lots of reading on the site and learned a great deal. I do have what I think is an issue, but my pool installer didn't seem to sound concerned when I mentioned it. There is one return that is always streaming air bubbles when the pump is running. The next nearest return has some bubbles but much less than the other. The other returns show no signs of bubbles at all. After reading posts in one of the older forums, I'm worried that I may have a leak in a pipe leading to the pump and that future problems will be encountered. Can anyone tell me if I have a problem or not??
