Q. What's the difference between 5/8 and 3/4 garden hose?

Answer

Water pressure is proportional to the hose's diameter and length, therefore a smaller hose (5/8 inch vs. 3/4 inch) would deliver a narrower stream of water. The 5/8-inch hose will not let the stream surge out in large torrents when you water the yard, leading to puddles and flooding. The broader 3/4-inch hose, on the other hand, allows for a greater quantity of water to be delivered per unit of time. There are a number of length options for both 5/8- and 3/4-inch hoses. It's up to you to decide what's best for your situation.
