2 years ago when blowing out the trailer, I forgot to reduce the pressure from my compressor and accidentally hooked up with 125psi, rather than closer to 60psi. I didn't have any damage other than the valve of the toilet was the first thing to blow and shoot water everywhere. Had to pull the toilet, order the new valve ($25 I believe), replace and reinstall. Wasn't too bad, but what a big mistake I'll never make again.
