Had my Carver 405 now for 14 years and love it. As always I have something to fix. It seems the floor is getting wet below the steps going into the aft bedroom. Using an endoscope and looking under the hanging closet , I did find water coming in when the shower is running. It has to be a DRAIN LEAK as the shower is all sealed fine. I’m thinking the only thing to do is unseal the floor drain and see if there is a connection issue. Anyone else have this problem.
