I've replaced hose fittings with new plastic, which I consider junk. My
new-last-year yard has taken a lot of work in landscaping and caring for
artificial pond. Our water has a huge amount of iron, and when the
outdoor connection (on hose reel) leaked a lot, the connections got
pretty nasty. I took off the reel-to-faucet connector, soaked the
fittings in CLR, and....voila! Then, for that particular PIA, I'm going
to put it on quick connects and seal them up with silicone caulk. I
have 100' of hose to haul around for various projects, and I am
meticulous in making sure I don't screw together any fittings with sand
on or in them; those don't leak.
After I get the veggie garden planted, I'll be making some concrete
stepping stones shaped like grape leaves, and put a few along the
concrete edging I make for flower beds. Google maps will think there is
a Jack-in-the-beanstalk down here ;o)
