I had a leak start under the kitchen sink at 3 AM in the morning on Christmas Eve. First thing in the morning, I went to Lowe's and spent $200 on plumbing parts to do the repair as I didn't want to call a plumber. It was -7F ambient, 15 MPH wind. I fixed it in time to prevent any damage.
Good for you!
Hubby is a fixit guy too.
