Water sprays out between handle and hose
The typical hose end (female) also includes a rubber washer that mates with the inside of the fitting and th end of the handle. They wear, they age, they get lost. (should I have used semicolons? That's another SE)

Easily determined to be missing. Look into the hose end. If you see the washer, replace it. If you don't see the washer, hop over to the hardware store of choice and ask for a hose end washer.



The washers are going to be varied in color and some may not have the tiny ears that allow them to listen to water flow. Not really, the ears keep them from falling out, as they will push beyond the threads and hold the washer in place. You probably have to buy three or four or five, use one and lose the rest in the clutter when you need them again. No, wait. That's me.
