How do you connect PVC to metal faucet?
Wrap plumbing tape around the threads of a MPT (Male Pipe Thread) brass or copper faucet and screw on a PVC female adapter to connect the faucet to PVC pipe. Tighten the connection by holding the faucet with slip-lock pliers while you turn the adapter with a wrench. Glue the adapter to PVC pipe with PVC cement.
How do you connect PVC conduit to metal electrical box?

How do you attach PVC conduit to metal box?
The PVC conduit is solvent welded (glued) to an adapter with male pipe threads on one end. The threaded end of the adapter is inserted into the knockout and a locknut is screwed on inside the box. If the box is a wet-location rated box with built-in threaded fittings, the adapter is threaded directly into the box.
Can you connect plastic pipe to metal pipe?
To successfully connect plastic and metal pipes, you need threaded connections. The plastic male thread must connect to the metal female thread. If you try to connect it the opposite way – a plastic female to metal male – then the connection will ultimately break or leak.
Can you cut cast iron with a Sawzall?

Do PVC threads need Teflon tape?
The right way to assemble a threaded PVC joint-Schedule 40 or 80 is finger tight plus one to two turns-no more. Two turns past finger tight plus the stress of the system pressure is within the tensile strength of one-inch PVC. Don’t use Teflon tape, Teflon paste or pipe dope. Do use a sealant.
