Go back to the shut-off valve and slowly turn the water supply back on. Return to the filter and carefully inspect both connections for any signs of dripping or leaking. If a leak is detected, use the adjustable wrench to tighten the leaking connection slightly until the leak stops.

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.

There you go. Everything's connected. Go turn the cold water back on. Once the water's running, check both connections to see if there are any small leaks. If you see something, just give it another turn with the wrench to tighten it up.
