Possessed Sink

[Clog Pro]

A customer called today saying their sink is possessed, haha.

They said that the kitchen sink will just spew out water for about 3 seconds a few times a day without anyone actually turning on the sink.

Anybody encountered this before?

Is this in a condo or an apartment?

Or is it from an air gap, when the dishwasher runs?

Water spewing out of WHERE?
