Shower Drain Leak 2012 16' Sport

[debrunyon]

When I use the shower (and only when I use the shower), water leaks out the bottom of the trailer right behind the right wheel. I thought it would be straightforward to access the area under the shower pan but "heck no"! I removed the belly pan only to discover that it only exposes the waste tank. Any advice on how to access the shower drain line between the shower darin and tank would be greatly appreciated.

Wow, that's two posts today, same issue. First, make sure it's the drain. Pour a bucket of water in the shower to see if it leaks. If not, then it is likely a bad fitting leak at the shower control valve or where the handheld hose goes in behind the wall. If the bucket test passes, run the shower with the wand in a bucket...if leak occurs, then yep it's not the drain it's somewhere in the supply.

Thanks for the suggestion. I did confirm that the leak is in the shower drain line. Looks like a real PITA to access the line. My guess is that I will end up cutting an access panel in the belly skin (not belly pan as I have already removed it). Airstream should have made this area accessible since even replacement of the shower drain requires access to the area under the shower. I have an e-mail submitted to Airstream USA to get advice. Hoping to do this myself as I live 2-1/2 hrs from the dealer.

How did you end up accessing the drain line? Did you cut an access panel? Did Airstream respond? I have the same issue and would like access ideas.
