Welcome, glad you figured out the water valve issue. I have a 2018, 30ft Thor 4 Winds, used, and they buried the on /off valves so far down into the compartment, which was under the bed, It took me looking 5 times looking to see them at the bottom of the space. Could they have made the levers any smaller, i don't know....
The answer to your question is, store your broom in the shower.
Jeanie, a happy camper
