Cleaning my lines for spring

I did like I always do and flushed the lines Then I put in a tank of bleach treated water and then set a few hrs and ran the lines to get the bleach water out I ran it till it was empty and replaced with fresh water. I turned my by pass to fill the water heater. when running the water there was a lot of air in the lines.it took a while but all are working fine but the sink in the bathroom. It started to sputter but lots all pressure and the out side show was the same way and the shower head is below the sink.I wonder if there is still a air bubble in the lines. It works but just a trickle of water comes out. Any ideas or help would be great I have a 2011 Winnebago .

Thank for this great site.
