I have a new gunite, salt water pool, and, since it was started, there have been bubbles spitting from the first pool return. I, and my pool builder, were concerned about a leak in the system. However, my PB now says that, after a thorough review of the system and researching the issue, he believes the spitting bubbles are hydrogen created by the SWG and that nothing further can be done to prevent it. Is he correct? The spitting is loud and annoying. How can I be certain it is not caused by a leak, preferably before I make final payment to the PB?
Bubbles Spitting from Return - Is SWG the cause?

A nominal amount of bubbles emitting from the returns is normal variant for a SWCG pool. If it is really noisy though, I would check for ways that air may be entering the system.
The SWG will produce many small hydrogen gas bubbles, though I have never heard them described as "spitting". There is an easy way to test if the SWG is causing your issue, turn the SWG off, or set the percentage setting to zero percent. Then the SWG will stop producing bubbles and anything that remains is caused by something else.
When my water is borderline low and my skimmers are sucking in water, I get bubbles. It's an indicator for me to add water to the pool. Happens when I get lazy or have a busy week. That could be another cause if you're retrieving water from skimmers.
