Drip, drip, drip: uncover the hidden reasons behind your faucet’s constant flow

A persistent dripping tub faucet can be an annoyance, a waste of water, and even a potential source of damage. If you’re struggling to stop your tub faucet from dripping, don’t worry – you’re not alone. This common plumbing problem can have several underlying causes. In this comprehensive guide, we’ll delve into the reasons why your tub faucet won’t stop dripping and provide step-by-step solutions to help you resolve the issue effectively.

Causes of a Dripping Tub Faucet

1. Worn-Out Washer: The washer is a small rubber or plastic disk that creates a watertight seal between the faucet handle and the valve stem. Over time, the washer can wear out, causing water to leak through the faucet.
2. Faulty O-Rings: O-rings are small, rubber gaskets that seal the connections between different faucet components. If an O-ring fails or becomes damaged, water can leak from the faucet.
3. Damaged Cartridge: The cartridge is the main component that controls the flow of water in the faucet. If the cartridge becomes damaged or clogged, it can prevent the faucet from closing completely, resulting in dripping.
4. Loose Handle: A loose handle can cause the valve stem to move slightly, even when the handle is in the “off” position. This can create a small gap through which water can drip.
5. High Water Pressure: Excessive water pressure can put stress on the faucet components, causing them to wear out prematurely and leading to leaks.
6. Sediment Buildup: Minerals and sediment from the water supply can accumulate in the faucet and interfere with the proper functioning of the valve stem and cartridge.
7. Frozen Pipes: In cold climates, pipes can freeze and expand, causing the faucet to leak when they thaw.

Step-by-Step Troubleshooting Guide

1. Inspect the Washer: Remove the handle and check the washer for wear or damage. If the washer is damaged, replace it with a new one.
2. Replace O-Rings: If you suspect a faulty O-ring, remove the faucet handle and inspect the O-rings for cracks or damage. Replace any damaged O-rings with new ones.
3. Inspect the Cartridge: Remove the handle and cartridge assembly. Inspect the cartridge for damage or clogging. If the cartridge is damaged, replace it with a new one.
4. Tighten the Handle: Remove the handle and check if it is loose. Use a wrench to tighten the handle securely.
5. Reduce Water Pressure: If the water pressure is high, install a pressure-reducing valve to reduce the pressure on the faucet.
6. Clean Sediment Buildup: Remove the aerator from the faucet and soak it in vinegar to dissolve any mineral buildup. Clean the rest of the faucet with a soft brush and mild detergent.
7. Thaw Frozen Pipes: If you suspect frozen pipes, apply heat to the pipes using a heat gun or hair dryer. Do not use open flames.

Advanced Troubleshooting Tips

If the above steps do not resolve the dripping issue, consider the following advanced troubleshooting tips:

1. Replace the Valve Seat: The valve seat is a metal or plastic component that the valve stem seals against. If the valve seat is damaged or worn, it can cause water to leak.
2. Inspect the Supply Lines: Check the supply lines for leaks or damage. If a supply line is leaking, replace it with a new one.
3. Call a Plumber: If you are unable to resolve the dripping issue on your own, contact a licensed plumber for professional assistance.
