Align the spout and push it firmly back into the faucet body. You should feel it seat properly. Once in place, use the Allen key to tighten the grub screw clockwise until it is snug, securing the spout. Turn the water supply back on and test the faucet by turning on the water and swiveling the spout left and right. Check carefully for any leaks around the base. The repair is complete when no water leaks out.

Goal: To finalize the repair and confirm that the leak has been resolved.

FAQs

How can I tell if my single-handle faucet is a ball-valve type before buying a repair kit?

Ball-valve faucets typically have a single handle that pivots and rotates on top of a dome-shaped cap. When you remove the handle, you'll usually see a cap secured by screws, covering a plastic or metal ball. If your faucet has a cartridge (a cylinder with O-rings) or two separate handles, it's a different type and requires a different repair kit.

Do I really need all the specific tools listed, or can I use alternatives for this repair?

While the listed tools are ideal, the most crucial are an adjustable wrench, various screwdrivers (especially a flathead for prying), and a hex key if your handle has a set screw. A good pair of pliers is also very helpful. You might be able to substitute some specialty tools with basic equivalents, but ensuring you have the right sizes will prevent frustration and potential damage.

What are the most important safety precautions I should take before starting this project?

The absolute most critical step is to shut off the water supply to the faucet, either at the supply lines underneath the sink or the main house shut-off. Always double-check by turning on the faucet. Also, protect your work area with rags or towels to catch any residual water, and wear gloves if handling old, potentially corroded parts.

How much does a typical faucet repair kit cost, and is 2 hours a realistic timeframe for a beginner?

A standard ball-valve faucet repair kit usually costs between $5 and $20, making it a very affordable repair. For a beginner, 2 hours is a reasonable estimate, but allow yourself extra time, perhaps 3-4 hours, for unexpected challenges like stuck parts or identifying the correct repair kit. Rushing can lead to mistakes or damage.

Then we just want to put the spelt back in and reverse order. Actually that's a lot more tight. It feels stiffer. It definitely feels better. I'm not going to use the new screw because it's already in there. It seems to be tightening up fine. If it's been rounded off or anything you have got that spare there or if you've lost it then you've... Then you've got that there. Then we want to tighten it back up where is it? Actually better to use this one because of the spin it. I'm going the wrong way. You can spin it all the way around. I'm not sure that's enough. One other thing I forgot to mention when you're doing this. When you're doing it you've got the split of the rubber here, of the plastic. That gap there is for the screw to go in. You want to be lining that plastic up roughly where the hole of the screw is. That should be it. See if we've done it. Now we've got no leaks coming out of there like we did before. Get the grease on there. I think it feels a lot stiffer. It's a nice new rubber. Thanks for watching.
