Hi all. I see this subject has come up a few times over the years and some solutions have been proposed and other questions unanswered, so I’m hoping to rehash the topic and hopefully get some fresh thoughts on a solution. I have a new build with a bubbler that intermittently spins. Covering it fixes the problem momentarily and it persists no matter how much pressure I send to it from the valve. I’m hoping there’s a quick fix I can do myself before having to get the builder involved as a warranty item. Thanks!
