So I determined that my anti-back flow valve requires replacement. However, in trouble troublr, I removed the faucet handle and damage a locking nut. So, I need to replace the faucet. The faucet is caterized to a L pipe, made of copper. The copper pipe is then attached to a plastic pipe. What's the best way to detach the copper from the plastic? Is there something else I should be doing to fix my issues?
