Hello. I am installing a new vanity, sink, and faucet. The existing p trap is metal and the center of trap opening is 8" off wall. The new sink drain center will be 9" off wall and the drain is plastic. How do I connect the sink drain to the trap despite the difference in materials and the offset? I have read that I should connect metal to metal but I am hoping there is some way. Otherwise, I could use the metal drain off the sink that is being replaced, but the 1" offset is still an issue. Looks to me like the straight end of the existing trap is sweated over a copper stub that is secured with compression washer and nut to Sched 40 pvc drain pipe so I suppose that one solution is to connect a 1" longer new pvc trap to the drain pipe. Any other way? I would like to avoid opening up the wall to get to the nut and vertical pipe. Any guidance is appreciated. Thanks.
