My new vanity/sink does not align with my prtap and it looks to me like everything is glued with pvc cement. Can I cut the drain pipe of my sink and install one of the short acordian pices to fix this or will it clog easily? Also my top of the pvc is 1and 1/2 inches how can I increasd the acordian pice to 1and 1/2 it is 1 and 1/4
