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.

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.
