Two-Handle Kitchen Sink Faucet Leak Repair

Watch on YouTube

What happens here

Take the new replacement cartridge (stem), which is a Danco 3S-9H/C Hot/Cold Stem compatible with Delta, Glacier Bay, and AquaSource faucets. Compare it visually with the old cartridge to ensure it's the correct replacement. Apply a small amount of plumber's grease to the O-rings on the new cartridge. This lubrication helps create a better seal, reduces friction during installation, and can extend the life of the O-rings. Carefully insert the new cartridge into the faucet body, making sure it is properly oriented and slides in smoothly. Then, thread the packing nut back onto the faucet body. To avoid cross-threading, turn the nut backward a few turns until you feel the threads engage, then tighten it forward by hand. Finally, use an adjustable wrench to snug the packing nut tightly, but do not overtighten, as this can damage the new O-rings or the faucet body.

Goal: Install the new faucet stem for leak-free operation.

What they say

Hide

was a little wore out. I don't know but I just know it wasn't working. Right? Okay. So with the little cartridge. So with this replacement cartridge that I bought, right? It's my Danco and it's a 3S-9HC hot water or cold water. It says it's for delta glacier bay or aquasource faucets. Right? And this is a pro source slash aquasource I guess. I'm assuming they're the same thing. Lose brand. Right? And I'm just going to orientate these to where they're the same. Right? So if you look down on that, this is the way I pulled it out and this is the way it's going to go back in. And before we put it back in, I'm just going to take a little bit of plumbers grease and stick it around that o-ring. Just get that nice and rubied up. They feel like they want to cross thread. Just make sure you go backwards, right? Start and reverse. Get it to catch and then hook it up like this. Make sure this is nice and snug. If not, it's going to leak on you.
