Water leak

I got the leak fixed. It did not require any tools. I realized that the tube coming to the hot water side came in from the side and then 90 degree turn up to the faucet. What was happening was when I was tightening it before it was preloading the pipe to want to untighten the fitting. So what I did was loosened the fitting pushed the pipe a little against the direction that you tighten the fitting then tightened the fitting now when you let go of the pipe it is trying to tighten the fitting instead of loosen it. Its kind of hard to explain it but hopefully you can picture what I'm talking about. Any way the leak is fixed. We just got back from our second trip and it would usually start leaking after 12 hours this time it never leaked.
