I keep having a waterleak on the hose coming into the trailer. I have put a new washer, used teflon tape and have tightened it up as much as I can an it still leaks! Any suggestions.
Try replacing the “city water inlet” on your RV. The threads on the inlet become soft and the fresh water hose doesn’t firmly seal causing it to spray or leak. Usually, 3 screws gently pull and replace.
