Store Sprayer for Winter

What happens here

With the sprayer thoroughly drained and cleaned, the presenter manually moves it into a large garage, which he refers to as the "Mega Shop." He mentions a link to videos about the shop at the end. He explains that leaving all valves open will allow any remaining moisture to fully drain and prevent freezing. The sprayer is placed on a pallet jack for easy storage.

Goal: Safely store the winterized sprayer.
