I live in South Orange County, CA (Southern California). My home was built in 2001 and it has suffered two pinhole leaks in the same area of piping about 2 years apart. My home has copper M. All the newer developments from 2001 and beyond in South Orange County, CA were build with Copper M piping. Pinhole leaks in all the newer communities is extremely common. Even homes much newer than mine are suffering multiple pinhole leaks and since the piping is run in the slab it can be quite an issue. Most of the repipe companies in the area are saying the pinhole leaks are being caused by the use of copper M combined with the water companies addition of Cholormine to the water. I obviously would like to prevent repiping. I am wondering I could get long-term results by installing a whole home Water Filtration system. The system I am considering would have Backwashing Catalytic Carbon Filter for removing Cholormine and a softener to prevent hard water. Can a whole home water filtration system help he get longevity out of my copper M plumbing system without future pinhole leaks? Thanks in advance for your suggestions.

I have a new construction home with a water softener loop plumbed with 1/2 in (I think) pex. I purchased a water softener that has 1 in male threaded connectors. I was going to use shark bite fittings and pex to make the connections but can't find 1/2 in push to 1 in female so I'm not sure the best way to proceed . Any advice is appreciated .
