Dealt with this exact issue last summer at a coastal rental. Salt air destroyed the sensor contacts in under six months. Had to redo the whole setup with stainless parts, which held up perfectly. Always push for the better materials now, learned that lesson the hard way.

In my old flight club, we had a Piper Archer that needed hose clamp checks every 50 hours. Spotting one crack is good, but in my experience, you should never rush checks even without a warning sign. The checklist is there for a reason, and skipping steps can lead to bigger issues down the line. I learned that the hard way when a friend missed a fuel leak. Now I double-check everything, no exceptions.

For years, I brushed off hard water complaints as mostly hype. Then my cousin moved to a town with terrible water and her chronic redness cleared up after installing a softener. That film wadereed mentioned is real; it stops soap from rinsing clean and leaves residue. It's not everyone's issue, but for some, hard water is a big piece of the puzzle.
