I have to thread a PVC into a brass fitting for my main to RPR valve should I use tape and putty or one or the other I was told to tape the PVC threads (male) and putty the inside of the brass fiting(female).

Thanks
 
Melts the plastic.


By the way, the most common cause of leaks involving plastic threads is OVER-tightening. The manufacturer calls for hand tight plus about one turn by wrench. The lubrication provided by tape or dope makes it deceptively easy to overtighten.
