Has any other owner of the Aliner E3 experienced the galley sink leakage, warpage issues? After the first year of ownership I saw the sink plumbing begin to leak. I discovered the drain that is installed in the plastic basin was mounted incorrectly, I reversed the gasket, added plumbers putty to the inside of the basin and was good for a while. But now the sink is warping due to it being plastic, because of the way it is folded into storage adds pressure from the drain hose. I am thinking of finding a metal or ceramic sink in similar size but then I worry the hose may break as it needs some flexibility during the transition from the up to down position and visa versa. At a loss. Can anyone offer some suggestions, mod kits, or DIY advice?
