water leak 92 Sovereign

[dikku@mac.com]

Please Help!
We just purchased a 92 Sovereign 21 foot Airstream. My wife hooked up the water line with a hose and cleaned out the shower. She left the water hooked up all night. This morning I noticed that the floor adjacent to the shower was wet and there was a steady drip below this area on the underside of the trailer.
Does this indicate a burst pipe? We could hear a steady drip with the water attached and turned on, while we sat in the bathroom. This disappeared when we turned the water off.
Thanks,

Sounds like a loose fitting more than a burst pipe. If the Pipe was burst the interior would be more like a swimming pool It could be a cracked fitting, the Grey pex is known for that.

Since the water is showing up in the bathroom, I would start with the fittings under the sink, they are the easiest to get to. Second would be the fittings on the rear of the toilet. These sometimes leak after an improper winterizing, or just from age. Last would be the backside of the shower fixture. I am not familiar with your trailer so I cannot offer a "how to" on getting to the back of the shower faucets.

I disconnected the supply hose with the pressure regulator and the drip stopped. I turned on the water pump and then the shower and no leak. I assume the leak must be in the plumbing in from the external water supply.
I am having trouble looking behind the toilet due to the confined space.

You would think so

But that is only really telling you that the leak shows when under full 45 PSI pressure. The pump cuts out at 30-35 PSI in most cases.

If you can get to where you can see the plumbing that comes in from the city water connection I would check it too. These water system leaks happen in the strangest places.
