Im dropping my Civic soon, and Im also looking for one. Is this good? Its made by KD tools but looks exactly the same as the Snap-On one.

It is not PEX, it is PVC, an inch in diameter and baby blue in color. Very common in the Phil. It cannot handle hot water thats why they use galvanized pipes for hot water.
