I hear swirling or sloshing water while the bubbler is running.

If you’re hearing swirling or sloshing noises while the bubbler is running, try the following:

1. The 4″ Bubbler was installed too close to a wall or other feature in the pool which causes a harmonic wave to occur in the water.
   1. Angle the eyeball differently to change the water harmonics.
2. Try changing your GPM flow rate using a flow control valve.
