If you mess about a lot with hoses, you can save a lot of time with quick couplers. I’ve only used these brass ones with zero problems, and there are plastic versions which may be just durable. In my case, where I’m more or less hand irrigating a couple of acres, dragging around and joining 100′ hoses, and attaching a variety of sprinklers and shut-off valves, they’re a luxury. I do wonder if I’m significantly reducing water flow by having several inline, haven’t figured that part out yet, but there’s no obvious noticeable difference. The couplers also come in handy for changing nozzles on a single hose, like in the greenhouse, where I regularly use a gun-type nozzle, water breaker, fan head and watering wand. In this application, an inline mini shutoff valve placed between the hose and the female fitting completes the convenience. They come in pairs, but you probably need way more male fittings. I get mine at Lee Valley (click the link), where you can get singles. I’ve seen the same ones at hardware stores. Get extra step washers as well!
