[Market-farming] Leaking Hose

I have volunteers who do work for me, sometimes using hoses. I've discovered
some of them do things that will result in leaks in hose connections.
Sometimes they don't like the way the watering wand is positioned, so
they'll take it off and put it back on. They will sometimes cross the
threads and there is no seal. Water leaks all over. Then, hoses today often
come with plastic hose-end fittings. Once you cross them, they are hard to
fit properly. They want to follow the new track created by the crossing of
the threads. After time you just have to cut off the old fittings and buy
replacements. Then you run into the situation where the replacement fitting
isn't installed properly and it leaks. I find my self repairing repair jobs
sometimes. Then there are those folks who like to kink the hose to stop
water flow. It's easy! But it results in the hose wall breaking down and
breaking open at the sharp points of the kinks. Sometimes this happens
accidently, but when it is repeated the hose breaks down. There's also the
issue of letting pressure build up in those hoses. Often this happens when
they are kinked or when the little swivel valves are put on the hose ends,
just before a nozzle or wand. It is convenient to "turn off" the water right
there. But then if it's left that way for who knows how long, the pressure
in the hose works on the fittings. If they've been kinked or if pressure is
high, the integrity of seals just starts to break down.
When I was an undergrad I had a couple of projects in the University
greenhouse. The greenhouse manager was a "drill sergeant" about how folks
handled hoses. I didn't like it but later I appreciated how important good
hoses were and how good habits made a huge difference in how they worked and
how long they lasted. Water under pressure is incredibly capable of
discovering and exploiting weak points.

" leaks behind the couplings of garden hoses?"
Are you meaning where rubber hose meets metal hose end, or
where the swivil part of the female end meets the metal end?
