Sounds like the the bypass valve may have been disturbed and so water is coming out of the air bleed hole.

I suggest you turn off the pump, remove the bypass valve cover (clear part that quater turns off bayonet style), extract the red valve (careful not to lose spring), rub some pertoleum jelly (vaseline) around the seal of the red valve, replace spring, red valve, press the red valve a few times to ensure it returns, replace clear cover and turn pump back on.

This should ensure the valve is working.
