odd leak

[IHalterman]

OK, We have an odd problem.
We have a 2015 Forest River Wildwood 30QBSS.
The connection for the cold water line to the kitchen sink leaks. Now, it only leaks when the shower is in use. I've taken the fitting off and replaced the rubber compression ring/gasket, but it still leaks when the shower is running. We have a bread pan catching the water and it will stay dry until someone showers then it dumps about 1/4 inch of water into the pan.
I'm so confused. We have tried running the bathroom sink both hot and cold, nothing. Run the shower Bam! Water in the pan.

Sounds like maybe a backflow issue??

You don't say but we have to wonder why you're trying to fix something that is very likely covered under warranty?

Smh.......
Maybe he didnt want to deal with the stealership over a simple fix. Or a long drive. Thats his business....

Flair-It fitting from PEX to 1/2" thread for faucet? If so, leaking from threads?
