bathroom sink water leak

My 2012 Montana 3585 5th wheeler has developed a leak under the bathroom sink, but it only leaks when I turn on either hot or cold water at the faucet in the water hook up bay from outside the coach. I didn't think to drain that outside faucet when winterizing, so I am assuming something froze.

Would seem like a good idea to get under the sink and tighten the connections to the spigots. On my kitchen sink, they were so loose they were slightly dripping when I got it. I believe they are plastic and just a snug with some channel locks did the trick. My drain has a large nut that keeps the plumbing tight under the sink and it was very loose as well.

Is your outside faucet part of the plumbing on the inside under the sink?

leak bathroom sink

It must be tied in there as it does not leak unless the outside faucet is turned on, and it leaks if either the hot or the cold water is turned on. I should note it doesn't leak if the bathroom faucet is turned on.
