Only time I ever ran out of water was when I got lazy and just connected my hose to the 100 ft of hose the customer already had at the spigot. I realized pretty quickly what all that additional length and smaller diameter do to flow rate…
I now run with 100’ and 50’ sections. But I would do away with 50’ and go with 75’ as rarely will 50’ be able to do the job. Maybe a spare 25’ or two.
