Repairing a Delta single-lever kitchen faucet

Delta single lever kitchen faucet1 Repairing a Delta single lever kitchen faucetThe most common kitchen faucet in America for the past 50 years or so has without a doubt been the Delta single lever kitchen faucet. I have seen and repaired more of these faucets by far than any other faucet. If you know what you are doing, the repair is quit easy and this guide will show you how to repair a delta single handle faucet.

If you have to fix a dripping, leaking Delta faucet, just follow these directions. Unfortunately, many amateurs seem to have problems installing the new parts and end up calling a plumber anyway. This article will illustrate, step-by-step, how to disassemble, and re-assemble the key parts to make your Delta single-lever kitchen faucet work like new again.

Step 1) Turn off the water shutoff valves for the hot and cold underneath the sink, and turn on the faucet to relieve the pressure. If the faucet doesnt stop dripping, then you have a bad shutoff valve(s) and need to address that before continuing.

Step 2) Remove the handle by loosening the setscrew using an Allen key. The setscrew is located on the front of the handle, underneath a small cover.

Step 3) Loosen and remove the assembly cap using a pair of pliers in counter-clockwise torque.

Step 4) Remove the plastic cap, the rubber cap, the lever ball, and the 2 rubber cup washers and springs.

Step 5) Remove the swivel spout by pulling up and twisting it off of the faucet body.

Step 6) Remove the two rubber o-rings on the faucet body.

Installing the springs and washers is where many amateurs make mistakes. The springs go in the recessed holes first, with the narrow part of the spring facing up. Then the rubber cup washers go on top of the springs, with the cupped female side down surrounding the springs. It helps to use a small Phillips screwdriver or an Allen key to hold the springs and washers in place.

Next, install the lever ball, the black compression washer and the plastic cap. This also takes finesse. The ball must be installed so that the small metal tab in the faucet body is inserted into the rectangular pocket in the lever ball. The rubber must be pushed down and the plastic cap carefully centered and installed with the small tab inserted into its recessed spot on the top of the faucet body.

Finally, while holding pressure down to keep the ball, rubber and plastic cap in place, screw the metal cap back on the top and re-install the handle and fasten it with the setscrew.

Turn on the water, and test it out. If you have any leak, simply start over and carefully check which part is not installed correctly.
