Headscratcher

I have a 2022 coachmen freedom express 252RBS. The issue is when connected to city water there are no leaks, but when using the fresh water with pump there’s a leak under the bathroom sink. I’ve had it back to the dealership twice for repair to no avail. Hopefully someone can help?

It must be a loose connection some where. I had a similar problem on a fifth wheel years back. Found the loose connection and made the repair. The best time to make repairs is when we are on a trip, has been for me and often it has to be repaired.

As mentioned in another thread, check all the connections as they come from the factory only hand tight. Maybe your pump puts out higher pressure than your city water connection and that's why it leaks with one but not the other?

Finally after 5 visits for service, the leaks are fixed. The biggest leak was where connected to black tank flush. A pex clamp was being used on flexible tubing. They tell me it can’t be crimped tight enough on flex tubing
