On my BayStar Sport the duckbill drain is on driver side just aft of the rear tires. On some models mine included, the overflow pipe will siphon out water from the fresh water tank as Newmar did not plumb it correctly. One or more threads on this. Some people have solved this my putting a clamp on the duckbill to prevent the water escaping. They will remove the clamp when filling the tank then clamp if off again for travel.

I have not done this “fix” mainly cause we don’t dry camp and less than a full tank upon arrival is ok by me.

How about purchasing a flow meter off of Amazon.. about $25. I have one for filling black tank for a good flush and one on my fresh water feed off of my water softener to monitor how many gallons we use between regenerations.

Good to know.... Thanks for the info...
