Hello all, newbie here. Not an experienced plumber, but have spent plenty of time with pipe dope on my hands. Installed a bathroom faucet on my utility sink (3 hole, 4 " on center, pretty standard). It's leaking through the center hole at the bottom. Everything is tight, aerator is snug, just thought I'd check here before returning. It's a Delta Foundations faucet. Any information would be appreciated.
