Reno3 - Had a similar situation on my previous motorhome. Apparently the winter freeze/thaw had loosened the connection on the under side of my faucets. Drained the antifreeze, filled tank with fresh water and turned on the pump. Fortunately, heard the spraying water, shut off the pump and did not have any real damage except wet carpet under the sink. Taught me to shut off the pump except when using the water.
Looks like that is a design flaw in the 211, no shielding above the converter and it is located right under the kitchen faucets. A simple plastic shield would divert the water elsewhere. I am making a trip to Nappanee, Indiana this week-end and hope to go North to Elkhart to see the R-Vision factory. Will try to remember to mention that to them. I would not go back to that dealer, might even tell the story to some of my friends.
