Q&A for How to Repair a Delta Brand Kitchen Faucet

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 can't remove it, then replace it.

Look up the information booklet/sheet for the part number. Nearly every part manufactured has it's information sheets online in multiple places, and they often have the instructions for replacing and repairing parts, like the O-rings.

You'll 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.

Shut the water off below the sink or at the main valve, most likely in the basement or lower level. There is a knurled area just below the pivot of the handle that needs to unscrew to access the cartridge below it. You can get the replacement cartridge from any big box hardware store.

These are proprietary Delta quick connectors. You should be able to squeeze in on the edges of the 2 halves of plastic connector (farthest away end) and then rock it back and forth to remove. If it won’t remove, there is a thin oval-shaped spring wire that slides in a groove at a 45 degree angle around the two halves of plastic connectors. Take needle nosed pliers and grab wire in the middle (lowest portion) and pull down at the same angle to slide the wire off. The connector will fall apart, and can be reassembled once it has been disconnected. Hold the two halves in place on end of hose, slide wire back on in the grooves.
