Q: Since applying the supply lines to the faucet seems like the most difficult part of the job, why wouldn't someone push the supply lines through the top of the vanity and attach them to the faucet first (with plumbers tape, of course)? The plastic nuts, which secure the faucet to the vanity, could be slipped over the supply lines first for instance, and attached where they belong afterward. I ask this question, because the process I described doesn't appear to be the normal procedure.
Thank you! Bill
