How To: Dump the Tanks
Included with all starter kits at Happy Campers RV Rentals is a sewage hose. The first step is to ensure that both of the wastegates are completely shut. Once completed, connect the wastewater hose to the tanks via the bayonet cap. You will want to dump the black tank first so that the gray tank can help wash out any leftover residue. You will switch to the gray tank once the flow from the bank tanks ceases.
