Had a new house built 50 weeks ago the plumber used apex piping and stubbed out with 1/2" copper. Then he used 1/4" turn compression shut off valves to supply lines. In the last 2 months I've had three out of eleven start leaking at the compression area (by the farrel rings). Trying to figure out why.

Welcome to the wonderful world of cutting corners and you can expect a lot more leaks as the system ages.

The coefficient of expansion per degree temperature change will cause major problems as these dissimilar products with (copper /plastic) is why you need to make sure the installer has a masters license (for your locality) and has enough insurance to cover the costs as the product fails and causes mold and other problems

Most highly skilled plumbers may use a compression valve BUT the compression fitting is always after the shut off not before it, unless someone is looking to get and get out and do as cheap as possible job
