Question:

We just purchased the Lippert waste management system for our new RV. Our RV has 2 outlets, gray and a black, that need 2 hoses to come together As one. Does Lippert make the camlock Y connection for this?

Expert Reply:

The setup you have with two waste valves is going to require the tanks to be drained one at a time as they do not make a wye drain hose or wye camlock fitting for the Waste Master RV Sewer Hose part # LC359724. Typically, the point at which the black and grey water tanks merge for draining occurs at the valve with a sewer wye like the Double RV Waste Valve part # T38.

I have attached a list of our sewer wye valves for you if you would like to change your setup so that the black and grey water sewer tanks can drain at the same time but if not you would just need to use the same sewer drain hose on each tank, one at a time. In order to use the Waste Master RV Sewer Hose part # LC359724 for this purpose you could need an additional Camlock Connector part # LC360578 for the grey water tank sewer valve.
