Inspect the base of the removed spout. You will see two black O-rings. Carefully remove the old, worn O-rings. If they are brittle or stuck, you can use a small flathead screwdriver or a pick to gently pry them off. After removing them, clean the spout base with a rag or tissue. Take the new O-rings, apply a small amount of plumber's grease to them, and slide them into the grooves on the spout base.

FAQs

How difficult is this repair for a beginner, and how long should it take?

This repair is rated beginner-friendly, but requires patience and attention to detail. For a first-timer, expect to spend 1-2 hours from start to finish, including gathering tools and testing. The cost is usually just the repair kit, which is significantly cheaper than replacing the entire faucet.

How can I tell if my leaky faucet is a 'ball-valve type' and ensure I buy the correct repair kit?

Ball-valve faucets typically have a single handle that rotates and tilts to control both temperature and flow. To confirm, carefully remove the handle; if you see a cap underneath that unscrews to reveal a metal or plastic ball, seats, and springs, it's a ball-valve type. Always check your faucet's brand and model (often Delta) to find the exact replacement kit, like the 'DANCO Repair Kit for Delta W/212SS Ball 86971'.

What should I do if I can't find the water shut-off valves under my sink, or if they're stuck?

If you can't locate the hot and cold shut-off valves under the sink, you'll need to turn off the main water supply to your entire house, usually located in the basement or near the water meter. If the under-sink valves are stuck, try gently using an adjustable wrench to turn them, but avoid excessive force to prevent damage. If they still won't budge, it's safer to use the main shut-off or call a professional.

I replaced the parts, but my faucet is still leaking. What could be the issue?

First, double-check that all components, especially the new springs, seats, and the ball, are installed correctly and oriented properly according to the repair kit instructions. Ensure the new O-rings are lubricated with plumber's grease and seated perfectly without any twists or pinches. Sometimes, either over-tightening or under-tightening the cap can cause leaks, so adjust carefully.

water, but no mains. But you pull it out. Okay. Then you're going to slide this piece up that you unscrewed and you're going to have two O-rings, one here and one down here. On this particular faucet, I had two. This is what you call a retainer. Excuse me, my lost grip on my phone. This is what you call a retainer ring. And this wheel just slip off. But you're going to take your O-rings, slip off and replace them. And what they did, I called Delta, told them what my problem was. And they sent me three O-rings, which are right here. And there are RP20049. Actually, they sent me three of them, but I only have to use two. And so what I did is I just, I slipped these off. And they'll just, mine were so worn, they were so loose that you didn't even have to pry them off. They just, they just slipped off. Normally, you would need a flathead screwdriver, something to kind of kind of pick that up and pull it off, but not in, not in this case, men were so loose, they just slid right off. So what I did is I took me a clean ax, I wiped up my, after I got the O-rings off, I wiped this up, cleaned it up. I put my new O-rings on, I slid them on, put this one on first. And then the other one just slides over it and goes right on up to the top, and it's spot. And then I took a little bit of just a little tiny, little tiny bit of plumbers grease, faucet grease, little bit, and just smeared it around my O-ring on both places. Just smeared that plumbers grease around there. Then I took my faucet back over to my sink.
