How To Repair Leaking Delta Kitchen Faucet With Pull Out

Dripping Delta Single Handle Kitchen Faucet

My sister's Dripping Delta Single Handle Kitchen Faucet

A few weeks ago we went visit my sister in Texas. Not long after we got there, I realized that she was having a hard time making sure that her Delta Single Handle Kitchen Faucet would not drip after closing it.

She kind of had already figured out a way to do it, but it still took longer than it should. When I asked her about it, she complained that my brother-in-law had not had time to take a look at it.

Do you have any tools? I asked her. So she found me a small box with some screwdrivers, pliers, and other small tools. That was all I needed to get the job started.

FIXING A DRIPPING DELTA SINGLE HANDLE KITCHEN FAUCET

You just need three small tools to complete a Delta single handle kitchen faucet repair. Unfortunately, though, the culprit is most likely the faucet's cartridge, which you would need to either order online or go get at the store.

All in all, it takes about ten minutes to complete the repair, and this is all you need:

Small screwdriver
Allen Wrench (1/8" in this case)
Adjustable Wrench (big enough for a 1 ¼" or so nut)
Delta RP50587 Cartridge (confirm which one you need before ordering or buying)

STEP 1: SHUT OFF THE COLD AND HOT WATER VALVES UNDER THE SINK

Before you start disassembling your Delta Faucet, shut off your cold and hot water valves under the sink. Then, it does not hurt to open the faucet to both make sure that the water is off and to release any water pressure trapped in the faucet.

STEP 2: REMOVE THE BUTTON AND SCREW THAT HOLDS THE HANDLE IN PLACE

Once you have made sure that the water is off, the first step to complete this easy repair is to remove the screw that holds the handle in place. To do that though, you first need to remove the button/cover using a very small screwdriver or similar tool.

Once you have access to the screw, use the small Allen wrench to remove it. Then remove the handle.

STEP 3: REMOVE THE CAP

After removing the handle, you can proceed to remove the cap. This piece is there to make the faucet look nice, it should not be too tight. I was able to easily remove it with by hand.

STEP 4: USE THE WRENCH TO REMOVE THE CARTRIDGE RETAINING RING

An adjustable wrench is the perfect tool to complete this step. However, to tell you the truth, I didn't use one. The only one my sister had was too small for this nut. I ended up using a small needle nose pliers, it took me a bit longer and I had to be careful so I didn't get the piece all rounded, it worked, though.

STEP 5: REMOVE THE OLD CARTRIDGE AND INSTALL THE NEW ONE

The faucet's cartridge is held in place by the retaining ring. Once the retaining ring is removed, it does not take any effort to remove the old one and install the new one.

STEP 6: RE-INSTALL THE CARTRIDGE RETAINING RING

With the new faucet cartridge in place, you can start re-assembling the faucet. Start by re-installing the cartridge retaining ring. Hand tight it first, then use the adjustable wrench to tighten it a bit more.

Do not over tighten it! As you may have noticed, the inside parts of the faucet are all plastic so you can easily break them if you do it.

At this point, you should be able to open your cold and hot water valves and check for leaks. If it is all good, you can move on to the next step.

STEP 7: RE-INSTALL CAP, HANDLE, SCREW AND BUTTON

As the title's suggests, put the faucet's cap back on and hand tighten it.
