I’ve been fighting with a Fleck 5600SXT that’s introducing air to my plumbing each time it regenerates. This obviously makes horrible noise in the morning when people first open most faucets or flush toilets. I’ve replaced the air check valve and float assembly (twice actually, most recently preinstalled with a whole brine tank replacement) and the clear brine tubing. I saw someone else on here had an air draw issue that ended up being caused by a hairline crack on the injector assembly. I’ve looked closely at mine but didn’t see any cracks, and I’m assuming that because I see air traveling up the brine tube to the injector assembly (during brine draw) that the leak must be upstream (one of the connections inside the brine tank). Is my assumption correct? If the air check is working properly and there are no leaks, shouldn’t the brine tubing only ever have water in it and no air? Or am I misunderstanding something? I just can’t imagine which connection could possibly be bad down there, given the replacements I’ve done and things I’ve carefully checked.
