Begin reassembling the faucet by screwing the retaining nut back on by hand. Use pliers to give it a final snug turn, but do not overtighten. Place the handle back over the stem and screw the handle base on clockwise. Hand-tighten it, then use the rubber wrench for a final quarter turn to secure it.

FAQs

What should I do if I can't locate or turn off the hot and cold water supply lines under the sink?

If the shut-off valves under your sink are inaccessible or seized, you must locate and turn off the main water supply to your entire house before proceeding. Never attempt faucet disassembly with the water supply still on, as this can lead to significant flooding and water damage. Once the main supply is off, open a lower-level faucet to drain the remaining water from the pipes.

Are the specified tools (Adjustable Wrench, Phillips head screwdriver) the only ones I'll need, or should I have others on hand?

While the adjustable wrench and Phillips head screwdriver are essential, it's also helpful to have a small flathead screwdriver or utility knife for prying off decorative caps. A set of O-ring picks can make removing old O-rings easier, and a wire brush can be useful for cleaning mineral deposits on internal components. Having a rag or small bucket ready for drips is also a good idea.

My faucet is still leaking after I've followed all the steps and reassembled it. What should I check next?

If the leak persists, carefully re-tighten all connections, ensuring they are snug but not overtightened, which can damage parts. Double-check that the new O-rings and washers are correctly sized, seated properly, and that plumber's grease was applied. Sometimes, the faucet seat itself might be worn or corroded, requiring a specific seat wrench for repair or replacement.

How do I ensure I get the correct replacement O-rings and washers for my specific faucet model?

The best way to get the correct replacement parts is to take the old O-rings and washers with you to a hardware store to match them for size and material. Alternatively, if you know your faucet's brand and model number, you can often find a repair kit or parts list online. Always apply plumber's grease to new O-rings for a better seal and extended life.

as the original cartridge was so the handle will go on seamlessly. Now you can put the nut back on just hand tighten it and then once it's pretty snug, you can do the last turn with the pair of pliers or the wrench. Here's a closer look of what I was talking about. You see that the white piece has a flat part and a round part and then you look at the handle and it matches that. You just kind of want to slide it in there so it fits snug. Once you put the handle on, give it a jiggle so it fits in there and then hand tighten the round part. Once that's tight enough, you can break out the rubber wrench and give it one last quarter turn.
