I have a cozy cove with a knob the lets air in the lines to create bubbles. Well today I noticed some water around that area and went to investigate. When my pump is at its highest setting water starts coming out of the air line. When on speed 1,2,3 it doesn't come out. This has never happened before, pool is only 10 months old. What could cause this? Also water comes out of all jets equally so I would think a line could be pinched. All PVC is rigged except for what came on the cozy cove already. Here is a few pics.
