Is there a fitting, or a way, that will both convert a pipe from PVC/CVPC to copper and reduce the size?I have old copper pipes that continually spring leaks. These pipes run along the basement ceiling which are easily accessible. I am planning on leaving the copper pipes that come off the main lines and go up into the house to the faucets.I am planning to replace the main pipes with PVC/CPVC. The main lines are one inch and the copper pipes being left are a half inch.My question is, is there a fitting or a way, that will both convert the pipe from PVC/CVPC to copper and reduce the pipe from one inch to a half inch.Thank you
Copper female adapter to plastic male adapter. To reduce size use two reducing couplings, 1 to 3/4, then a 3/4 to 1/2. You may have have trouble finding a 1 to 1/2 reducing coupling. You might find a 3/4 to 1/2 reducing bushing, so you won't need a short piece of 3/4 pipe.
In the plastic, put on a slip x thread adapter- one side is the glue fit, the other is female pipe threaded. Then put a copper threaded adapter into the threaded side of the plastic. Do the reduction with plastic fittings to keep it simple. It you want to split the line so that you don't reduce the total volume drastically, put a tee on the 1 plastic and reduce each end of the tee to make two copper connection points.
cpvc, copper and pex pipe have the same outside diameter. You can run the mains (hot and cold) in cpvc, use reducing couplings or tee fittings to get to 1/2 or 3/4. From there you can use sharkbite couplings to connect the cpvc to copper.
