Hi all - we had our trailer winterized by the dealer last winter, and we just went to dewinterize it to take it camping. After we flushed the antifreeze and went to test the hot water heater, we turned off the bypass and hooked up the hose through the city water connection, but then water was spewing out of the brass valve at the bottom (shown in picture). I assume this is supposed to have a valve plug, and the dealership just forgot to give us the brass valve plug when we picked up the unit after they winterized it? Any insight would be appreciated!

Unit is a coachmen Catalina 154RDX. The water heater is “on demand”
