Product review (1 stars): I like reading reviews
I like reading reviews... but don't often write a review.  But I felt I should add this.
This connector appeared to work fine for about 4 days... no leaks, it worked great.  But last Saturday morning we woke up to a minor flood in our kitchen.  Water was spraying out of the compression side of the fitting.  The kitchen and dining room floors were all wet and water was going through the floor and dripping out of our ceiling light fixtures in the basement.  We are now looking at thousands of dollars in floor repairs.
I would not trust this part.
