Greetings:

I have an '06 Marathon conversion. I will be in a situation this summer where I will have to have my tanks pumped out rather than dumping in the usual manner. I have heard stories of people have had their tanks collapse during the pumping process. I was told that the key to to make sure that your "toilet" valve is open during the pumping. Not sure if this is even necessary or how to "hold the toilet valve open".

I am looking for advice on the proper way to pump the tanks.

Thanks in advance.

John Emmett
