The faucet cartridge or faucet stem is found on most styles of two-handle kitchen and bath faucets. This is the part that regulates the flow of hot and cold water. 

Now that you have inspected the cartridge or stem and identified it as the source of your leaking kitchen faucet or dripping bathroom faucet, you will need to replace it.

Cartridges and stems come in many shapes and sizes, and the easiest way to find the right replacement part is to know the faucet manufacturer’s name and faucet model number. If you’re not sure, take the old cartridge or rod you’re replacing to a shop so you can use a reference guide to match it to the exact cartridge you need.

To fix a leaky faucet, first shut off the water to your faucet by turning the valve under the sink. If there is no valve, turn off the water supply to your entire home. Open the faucet to empty the water from the pipes and close the drain so that nothing falls out while working. If there is a set screw behind the faucet handle, use an Allen wrench to remove it, then remove the handle. Alternatively, if there is a top screw cover on the handle, remove it with a flathead screwdriver, then loosen the screw underneath and remove the handle. With the handle removed, use a wrench to loosen and remove the nut from the handle assembly. Pull the handle cartridge up and out of the sink. Use a rag to wipe off any loose parts and the area around the handle. If the O-ring looks old or damaged, replace it. Obtain a compatible replacement for the old cartridge, then reinsert the new cartridge into the sink. Now tighten the nut in place with the wrench and reattach the handle. Finally, turn the water back on and check that your faucet is no longer leaking. If you need to learn how to repair a compression faucet or cartridge, read on! Our Moen high arc kitchen faucet started leaking around the base of the high spout. We’ve had the Moen Monticello 7700 series single handle faucet for 8 years and it still looks great, it just developed a leak around the base of the spout. Looking at the instruction manual for the Moen Monticello 7700 series faucet, this kitchen faucet has a lifetime home owners warranty and there is an o-ring (#25 on the parts diagram) that is most likely the source of the leak. Use the exploded view on page 2 of the manual to get the part numbers in the rest of the article.

The high arc faucet will leak around the base for several hours after it is turned off. It was mouthwatering after the faucet was turned off.

I called the 800 number at 1-800-289-6636 and asked for an O-ring kit for the faucet (I think ours is a model 7730). They shipped it for free in about 10 days. It included the leaky O-ring, the plastic ring that holds the faucet in place, and a pack of silicone grease to lubricate it during reassembly.

How To Fix A Leaky Faucet

To avoid hitting or scratching the faucet when I took it apart, I used a pair of strap wrenches that I bought at Menards ($3 a pair). They worked very well because the calcium build-up made the faucet threads very tight. Using the strap wrenches I was able to grip the chrome without scratching the chrome surface. When I first removed the nut, I had to use the small and large wrench to loosen the spigot nut (#26) without turning the spigot bridge ring (#30).

The rest of the faucet repair process is captured on video (below). It literally took me about 5 minutes from the time I got the free replacement parts from Moen to fix the leaky faucet.

On this same Moen faucet, I had to replace the cartridge. It started to leak a little and the single handle was hard to move. If you have a similar problem, check out my video on replacing the Moen 1225 cartridge found in the main handle of this faucet. It’s also quite simple to do yourself.

Is the Moen single handle kitchen faucet hard to use or leaking around the handle? If so, the 1225 cartridge can easily be oiled or replaced with a faucet.
