stopped up sink.
I have a 2007 Montana Mountaineer fifth wheel. The sink will not drain and the problem lies between the p trap and the gray tank. How do I get this in plugged.

A friend of ours had his galley tank plugged up......he took it to the shop and they found it was caked with old dish soap. He was using the cheapest dish soap he could find and they told him to use Dawn dish soap to stop that problem.
