How can I use with 2 sewer ports (one black and gray, the other black only) separated by approx 15-ft? Thanks!
Have a 2015 Newmar Canyon Star with bath-and-a-half. Mid-coach water bay has one sewer port for both gray and black, each with its own pull valve. The rear bath has its own sewer port below the rear bay. Could I use one of the portable Sanicon to work with both if I can set up electrical in each bay?
