What's the one tool you never service a porta potty without?
I'm new to driving a vacuum truck and servicing portable toilets. My route covers construction sites, weekend events, and long-term rentals. I've learned that having the right tools makes a huge difference when you're facing 40 to 60 stops a day. Some days it's a standard unit on level ground with easy truck access, other days it's a deluxe unit with a flushing bowl and sink tucked behind a food vendor at a festival, or an ADA-compliant unit on a muddy construction site where the truck can barely reach. I keep my basics covered: gloves, hose, deodorizer, and paper. But I want to know from experienced drivers, what's the one tool you never service a porta potty without? Is it something for unclogging, leveling, or dealing with frozen tanks in winter?
