Two-handled kitchen faucets give you separate controls over your hot and cold water inputs, which usually allows more control over the temperature of your faucet output. However, if your faucet starts leaking, you may want to know how to troubleshoot the problem and repair your Delta kitchen faucet without purchasing a new one. Depending on how your sink is set up, youll want to explore the connections and valves within the installation to test specific points.

Community Answer Spray it with PB Blaster and let set, then spray again. Make sure the Allen wrench is secure and turn outwards to the left. If you still cant remove it, then replace it. 
Community Answer Look up the information booklet/sheet for the part number. Nearly every part manufactured has its information sheets online in multiple places, and they often have the instructions for replacing and repairing parts, like the O-rings. 
Community Answer Youll need a swivel, optional size converter, and Teflon tape. The best units combine swivel, aerator, and side twist to spray, like a shower head. Note: faucets may have different sizes, a converter looks like a washer with threads inside and out. Note direction: you are usually above the faucet, looking down, so clockwise/counterclockwise orientation for tighten/loosen may appear backwards. Step 1: Remove old end, aerator (looks like a cap with a little screen), or previous swivel that broke and part is still there; carefully clean the threads. Step 2: Use one layer of Teflon tape around the outer threads. Converter first, then swivel. Hand tighten to be very snug, and do not wrench. Delta single-handle ball valve faucets are among the least troublesome to repair, although the fact the valve is spring loaded can make disassembly a little finicky. When one of these faucets starts to leak, its usually because one or both of the gaskets or springs in the valve seat are worn out. You usually can find a repair kit for your model at the hardware store, and if not, a universal repair kit often works. In some cases, the ball itself is causing the leak. If you have to replace it, you need the one for that specific model.

Considerations for Delta Kitchen Faucet Repair
When looking at a faucet repair, there are several components you need to consider. Faucets have many gaskets – circular components made out of a rubbery material. These gaskets help to insulate and control the flow of fluid from one pipe to another. However, gaskets can wear down over time, and the material breakdown can eventually cause leakage through a joint.
When you look at your Delta faucet and the connections under the sink, youll need to be able to identify which connections end up flowing to a particular designated output. Most systems allow you to check certain critical points to establish where a leak might be happening, which makes it a lot easier to address. You should also be able to identify where you can turn off the input from your water main. Identifying this location can help you troubleshoot the situation while controlling the water flowing to the questionable connections.
