Fixing a leaky Delta two handle faucet. This procedure can be applied to repair a two handle faucet from any brand whether it's leaking under the handles or from the spout. See the links below for the parts and tools I used (most Delta parts should be covered under warranty so check before buying anything):

Water collecting underneath handle = replace stem on leaky side
