Hello I wanted to ask a question about a project im working on at my house. I have a water line that is in the basement at the ground and my copper was damaged. I am deciding to start from the ground with pex and run it to my water heater and leave copper from the heater to the rest of the house. The problem im having is figuring out what kind of fitting I would need. I've looked only need and at the stores but haven't figured it out yet. I am a truck driver and am away from home for few months at a time and would like to get this project done next time I come home. I've included a picture of the ground joint and the elbow that was originally put in. Can you guys help me find what kind of fitting I would need to put in to this type of grounding house that I can use to connect directly to the pex and on. Thanks.
