Air in water lines

Interesting. I ran all water (every faucets). The spitting stopped in all faucets except kitchen. I need to find the pump and look to see whats happening there. A couple of things that I'm doing now to the trailer are that I just power washed the roof, now when it stops raining I'm going to scrape the mess of silicone and all the other **** off. It is a royal mess. Then I need to coat the roof. I need to replace the top vents as a couple of them are broke. I have a screen that was off when i got the camper, but it is just not going in. Just one of the many projects before putting it on the road. I've cleaned the camper from top to bottom with Lysol and hot water. The camper sat for more then 15 years and the mice had great parties in there. I've sealed all holes and properly cleaned it. Now I need to get mouse mix and place that all over. One more thing. I need to put air shocks or air bags in my truck to help when towing, but that will be one of the last things I do. I'm getting long winded and random here so I'll stop here. Talk to you all soon and thanks for all the great great advice!
