just finished replacing my kitchen sink yesterday... had to make a new drain pipe for it, and also do some minor repair to the countertop (had a hidden chip) anyway I got everything hooked up, turned on the water, and... what a mess! my new faucet was leaking water everywhere. It was a new Moen single handle deal with the spray nozzle, and it appeared to be leaking down the hose to the spray nozzle. This faucet uses an unusual method of connecting the hose to the faucet, instead of the usual threaded connection it pushes into a plastic clip and seals with O-rings. I suspect the plastic clip. Anyway, I'll be returning it and getting another faucet. Do Delta faucets use a more conventional method of connecting the sprayer nozzle hose? I put the old Delta faucet back in and it is working fine, it's just that the girlie wants a new faucet with a sprayer nozzle and this one doesn't have one.
Additionally, there was some serious foul-smelling black muck in the drain pipe when I disconnected the part I was replacing. This is an older house with cast iron drains, and it appeared that this muck was only in the cast iron pipes, not the newer pvc stub out to the fixture. Coincidence? Or should I think about having the pipes snaked out? There was a pretty serious plug right at the 45 degree elbow going out to the sink; probably 3/4 of the pipe was blocked. I knocked most of it out with a screwdriver and the sink appears to be working OK now. (it would occasionally drain slow before.)
