Leak under the kitchen sink

We're back to fix problems in our own house now.

There was apparently some leak under the kitchen sink. It's been there for years! We finally had it fixed this time. As it turned out, the caulks around the sink was dried out over the years to allow water to seep through when flooded. Exactly the same problem occurred several years back around the tub upstairs, showing up as water coming down the ceiling in the guest bedroom downstairs, when someone took a shower. Alas! How we don't usually learn and remember from our own lessons!

Also the flex-plastic-pipe coming down from the sink to the garbage disposal needed a bit straightening up, since its elbow was a bit too long for it to connect downward in a proper 90-degree angle. Propane gun was used to heat the pipe elbow slightly in order to change its shape as needed.

Come to think of it, this slow leak condition over the years could've also caused the small section of the wall in the dining room to peel off, as the kitchen sink is on the same side of the wall about 10-15 feet away.
