Matt,
No. You can bypass the holding tank and allow just gray water to escape through your sewer hose. Mr Johnson brings up a good point & that is why I run the water through the holding tank. But if you were going to do a lot of washing you could utilize the tank bypass valve.

***this is how my coach works....................remember not all Newells are the same, but I would guess that Tom & Patti's coach has this capability.
