Why Is My Bathtub Faucet Dripping

## Why Is My Bathtub Faucet Dripping?

A dripping bathtub faucet can be a nuisance, wasting water and driving up your utility bills. But don't worry, it's usually a relatively easy fix. In this article, we'll explore the common causes of a dripping bathtub faucet and provide step-by-step instructions on how to repair it.

### Common Causes of a Dripping Bathtub Faucet * **Worn washer:** The washer is a rubber or plastic seal that creates a tight seal between the faucet stem and the body of the faucet. Over time, the washer can become worn or damaged, allowing water to leak through. * **Damaged O-ring:** The O-ring is a rubber seal that prevents water from leaking around the base of the faucet handle. Similar to the washer, the O-ring can deteriorate over time or become damaged, causing the faucet to drip. * **Loose or damaged cartridge:** The cartridge is the assembly that controls the flow of water through the faucet. If the cartridge becomes loose or damaged, it can allow water to leak past it, causing a drip. * **Mineral buildup:** Mineral deposits can accumulate on the faucet's internal components, restricting water flow and causing the faucet to drip. ### Step-by-Step Repair Instructions **1. Identify the source of the drip:** Determine whether the water is leaking from the handle, the spout, or the base of the faucet. This will help you identify the likely cause of the drip. **2. Gather tools and materials:** You will need a wrench, pliers, a screwdriver, and replacement parts (washer, O-ring, cartridge) as needed. **3. Turn off the water supply:** Locate the water supply valves under the sink and turn them off. **4. Remove the faucet handle:** For most faucets, you can remove the handle by pulling it straight up. If the handle is stuck, you may need to use a screwdriver to loosen the set screw holding it in place. **5. Remove the faucet stem:** Once the handle is removed, you will see the faucet stem. Use a wrench to loosen the packing nut and pull out the stem. **6. Replace the washer or O-ring:** Inspect the washer and O-ring on the faucet stem. If they are worn or damaged, replace them with new ones. **7. Lubricate the faucet stem:** Apply a small amount of plumber's grease to the washer and O-ring to help prevent future leaks. **8. Reassemble the faucet:** Slide the faucet stem back into the body of the faucet and tighten the packing nut. Replace the faucet handle and tighten the set screw. **9. Turn on the water supply:** Slowly turn on the water supply valves under the sink and check for leaks. **10. Adjust the cartridge (if necessary):** If the drip persists after replacing the washer and O-ring, you may need to adjust or replace the cartridge. Consult the manufacturer's instructions for specific steps on adjusting or replacing the cartridge. ### Prevention Tips * Regular cleaning and maintenance can help prevent bathtub faucet drips. Use a vinegar solution to remove mineral buildup and lubricate the faucet's moving parts. * Avoid using harsh chemicals or abrasive cleaners on the faucet, as these can damage the finish and seals.
