Why I Believe 1 2 Pex To 3 8 Compression is Necessary

I recently had to replace a section of my plumbing system and I was faced with the decision of what type of connection to use. After doing some research and consulting with experts, I decided to go with 1/2 inch Pex tubing connected to 3/8 inch compression fittings.
