Sort of a little off topic, but I learned as far as plastic water pipe in the ground,
It is sort of a no brainer to use stainless clamps, but not all "stainless" aircraft style screw clamps are the same.
Some have metal/iron screws.
They last about 6 years in the ground before they rust/corrode and loose their grip.
It is no fun to dig up a line because the clamp screw is corroded.
I learned just because they say "stainless" on the band, does not mean they
have stainless screws also.
I now take a magnet to each and every clamp to insure they are not iron, but stainless.
