That's all there is to it.

I've been tying up this assembly too. However, I don't see how it could possibly fall over. The hoses are so thick and stiff you would need a crowbar to bend them.

The only reason I decided to replace the hoses is because I figured they might be getting brittle with age and could leak (and I had the galley off anyway).

I considered a seacock. But, then I would worry about if I remembered to close it when I left the boat.

The green water hose looks like it's just common garden hose. I thought about replacing that, but not much water is drank on my boat. Not the beverage of choice
