So I can't seem to get any traction from people on this and I'm really not interested in calling a plumber for $150/hr to do something that I can do. I need to replace this valve with a ball valve or some type of key valve like at the water meter. I'm getting mixed up as to how I remove this valve and what type of joints I should use for the next. I'd like to avoid soldering, preferably.
Any help? Anything special to connect the PEX to one end? I don't want to tear it and not be ready to put the new one on, then have no water. Looks like they soldered a stub into the valve and then on one end has a fitting to screw into the PEX and the other solders right onto the copper.
