No Pressure Kitchen Sink

[JIMNINA]

We have a 2003 Yellow Stone which seems to have a crazy problem. While using the fresh water tank it seems like the kitchen sink vapor locks, looses all pressure :( . To fix the problem we have to go into the bathroom and turn on the sink for a few seconds, turn off the bathroom faucet and then the kitchen faucet works correctly. The coach has one of the fancy advanced water manifold with lots of valves?

Many years ago, I had a problem with my kitchen faucet doing like yours. I removed the the screen filter from the faucet and turned on the water and flushed out what appeared to be plastic
that was plugging up the kitchen faucet. Since then never a problem.
