While that math all looks great on paper, in the real world there are more practical limits to hose lengths.
For example, there are few scenarios in which more than 100 to 200 feet of hose would be appropriate. Investing in the additional length of hose for infrequent use would be cost prohibitive when your Hotsy pressure washer has wheels and can easily be moved from one end of even a large warehouse building to the other.
In addition, more hose length also means more hose weight. Dragging an extra 50 or 100 feet of hose, filled with water, adds a burden of weight to operations. Let’s roughly estimate that every 100 feet of hose contains one gallon of water and, for the sake of simplicity, let’s say that with the weight of the hose that totals 30 pounds. That means if you add another 100 feet, you now have a hose weighing 60 pounds to drag around the job site. That’s not a ton, but it brings us to the third issue with increased hose lengths – wear.
With more hose being used, more hose also ends up lying on the ground. That means that as you move, you drag the hose across the terrain which can wear at the exterior of the hose and lead to premature failure. Longer lengths may also reach across access areas like driveways or vehicle bay entrances, increasing the possibility of a vehicle driving over and damaging a hose.
