I know some of you got the standard kitchen sink and water faucet set, as I did. Mine has been leaking for a few months, so I finally got around to fixing it. I was surprised to find out that it's a Delta faucet and that it has a lifetime gurrantee.

I had a hard time identifying the model, but once I did, I found the toll free number, called it, and then sent me a free kit. (pretty good deal, since I can't seem to find this kit in any of the hardware stores).

The model number I have is 470 (chrome plated version of a pullout handle kitchen faucet - sells for $200).

The toll free number was 1-800-345-3358 (345-DELTA).

The kits they sent to me were:
RP 70
RP 3614
RP 32542

(with the caution to discard the O-rings in the RP 3614 kit, which don't fit.)

The really fun part was trying to figure out what brand and model the the unit was. It only has a red/blue button on it, which I thought was for HOT/COLD. It turns out, that's DELTA's colors, too!
