Drip, drip, drip: uncover the cause behind your persistent tub faucet

Wondering why your tub faucet continues to drip even after you’ve turned it off? You’re not alone. This common plumbing issue can be frustrating, wasting water and potentially leading to more serious problems down the road. In this comprehensive guide, we’ll explore the reasons behind this persistent drip and provide step-by-step instructions on how to fix it.

Causes of a Dripping Tub Faucet

The culprit behind a dripping tub faucet is often a worn-out washer or O-ring. These small components play a crucial role in sealing the water flow from the faucet, and over time, they can deteriorate or become damaged.

Other potential causes include:

• Faulty cartridge: The cartridge regulates the flow of water through the faucet. If it becomes faulty, it may not close completely, causing a drip.
• Damaged seat: The seat is the surface against which the washer or cartridge seals. If the seat is damaged or worn, it can prevent the faucet from closing properly.
• Loose handle: A loose handle can cause the stem to move slightly, allowing water to leak through.
• Mineral buildup: Hard water can cause mineral deposits to accumulate on the faucet components, interfering with their proper function.

Step-by-Step Repair Guide

Fixing a dripping tub faucet is a relatively simple task that can be completed in a few steps:

1. Gather your tools: You’ll need an adjustable wrench, a screwdriver, and replacement washers or O-rings.
2. Turn off the water supply: Locate the shut-off valves under the sink and turn them off.
3. Remove the handle: Use a screwdriver to remove the handle screw and lift off the handle.
4. Remove the cartridge: Use an adjustable wrench to unscrew the cartridge and pull it out.
5. Inspect the washer or O-ring: Examine the washer or O-ring for signs of damage or wear. If it’s damaged, replace it with a new one.
6. Clean the seat: Use a rag or brush to clean the seat where the washer or O-ring sits.
7. Reassemble the faucet: Insert the new washer or O-ring, then reassemble the cartridge and handle.
8. Turn on the water supply: Slowly turn on the water supply and check for leaks.

Additional Tips

• If the drip persists after replacing the washer or O-ring, check the seat for damage. You may need to replace the seat or have it resurfaced.
• If the cartridge is faulty, it’s best to replace it with a new one.
• If the handle is loose, tighten the handle screw.
• To prevent mineral buildup, use a vinegar solution to clean the faucet regularly.

By understanding the causes of this common plumbing issue and following the step-by-step repair guide, you can effectively fix the drip and restore your faucet to proper working order.
