Reassemble the faucet by following the disassembly steps in reverse. First, screw on the cartridge retaining nut by hand, then use pliers to tighten it until snug. Next, screw on the large brass retaining nut and tighten it by gently tapping with the screwdriver and hammer. Place the handle back onto the valve stem, tighten the set screw with the Allen wrench, and press the decorative cap back into place.

Goal: Securely reassemble the faucet components.

  • Do not overtighten the nuts or the set screw, as this can damage the parts.

FAQs

What specific replacement parts will I need for both the faucet and water intake, and what's the typical cost?

You'll likely need new O-rings, washers, plumber's grease for the faucet, and Teflon tape for the water intake connections. These parts are generally inexpensive, typically costing under $20-$30 total for a basic repair kit or individual items. It's wise to have a small assortment of common O-ring sizes on hand before starting.

What's the absolute most critical safety step before starting, and what if I can't locate the shut-off valves?

Always turn off both hot and cold water supplies to the faucet using the shut-off valves under the sink to prevent flooding. If you can't find or operate these valves, or they fail to stop the water, you must shut off the main water supply to your house before proceeding with any repair.

After replacing O-rings and washers, why might my faucet still be leaking, and what should I check next?

If your faucet still leaks, first re-check that the new O-rings and washers are seated correctly and are the right size for your specific faucet model. The leak might also be coming from the valve seat, or the water intake leak might be the primary issue, so thoroughly inspect all connections for tightness. Sometimes, the faucet body itself can be cracked, though this is less common.

Is the estimated 3-hour repair time realistic for a beginner, and what should I do if I get stuck during disassembly?

Three hours is a reasonable estimate for a beginner, allowing time for identification, careful disassembly, part replacement, and meticulous reassembly. If you get stuck, refer to your faucet's specific manual or the manufacturer's website for detailed diagrams. The photos you take during disassembly will also be invaluable for guiding reassembly.
