After removing the old cartridge, look inside the empty faucet valve body. Use a clean rag, perhaps moistened with a small amount of white vinegar, to thoroughly clean the interior, removing any visible gunk, sediment, or mineral deposits. A clean surface is essential for the new cartridge to seal properly. Take the old cartridge you just removed to your local hardware or plumbing supply store. Show it to an associate to find an exact replacement part. This is the most reliable way to ensure you purchase the correct Replacement Faucet Cartridge for your specific faucet model.
This guide provides comprehensive, step-by-step instructions for fixing a common plumbing issue: a dripping two-handle bathroom faucet. The process involves shutting off the water supply, disassembling the dripping handle, identifying and replacing the worn-out internal component (typically a cartridge), cleaning the valve body, and reassembling the faucet for a leak-free result.
You'll primarily need screwdrivers (flathead and Phillips), an adjustable wrench, and possibly slip-joint or tongue-and-groove pliers for stubborn nuts. A bucket and old towels are essential for catching water. The specific brands mentioned are examples, not strict requirements.
For a beginner, this project typically takes 1-2 hours, including water shut-off and cleanup. The main cost is the replacement cartridge, which usually ranges from $10-$30 depending on your faucet's brand and model. It's a cost-effective alternative to calling a plumber.
A worn-out internal cartridge or O-rings are almost always the cause of a dripping faucet. To get the right replacement, identify your faucet's brand and model (often stamped on the faucet body) and take the old cartridge with you to the store for a direct comparison.
Always shut off the hot and cold water supply valves under the sink before starting to prevent leaks and potential flooding. Place a bucket under the faucet and have plenty of old towels on hand to manage any residual water in the lines.
