How to Fix a Leaking Bathroom Sink

Leaking bathroom sinks are a common plumbing problem that can be annoying and lead to water damage if not fixed promptly. While some leaks may require professional attention, many can be easily fixed with a few simple steps. ### Identifying the Source of the Leak Before attempting to fix the leak, it is important to identify its source. Check the following areas: -

Faucet base:

The base of the faucet where it meets the sink is a common spot for leaks. -

Drain:

The drain stopper or gasket may be loose or damaged, causing water to leak around the drain. -

Supply lines:

The flexible or braided lines that supply water to the faucet can become worn or cracked, leading to leaks. -

P-trap:

The curved pipe underneath the sink can become loose or clogged, causing water to leak at the connections. -

Sink basin:

In rare cases, the sink basin itself may have a crack or hole, allowing water to leak out. ### Step-by-Step Guide to Fixing a Leaking Sink

1. Gather Materials:

- Adjustable wrench - Phillips screwdriver - Plumber's putty - New washers or gaskets (if needed)

2. Turn Off Water Supply:

- Locate the shutoff valves under the sink and turn them clockwise to close the water supply.

3. Disassemble the Faucet:

- If the leak is coming from the faucet base, remove the aerator (if present) and use an adjustable wrench to loosen the mounting nut. Carefully lift the faucet assembly off the sink.

4. Replace Washers or Gaskets:

- If the leak is caused by worn-out washers or gaskets, replace them with new ones. Apply a small amount of plumber's putty to the gasket or washer before installing it.

5. Reinstall the Faucet:

- Position the faucet back onto the sink and tighten the mounting nut with an adjustable wrench.

6. Check Drain Gasket or Stopper:

- If the leak is coming from the drain, tighten the drain stopper or replace the gasket.

7. Fix Loose Supply Lines:

- If the leak is from a supply line, tighten the connection at the faucet and the shutoff valve. If the line is damaged, replace it with a new one.

8. Check P-Trap Connections:

- Inspect the P-trap for any loose connections or clogs. Tighten the nuts or clean out any debris.

9. Inspect Sink Basin:

- If the basin is cracked or has a hole, you will need to replace the sink.

10. Test for Leaks:

- Turn on the water supply and check for any leaks. If the leak persists, double-check the connections and tighten them as necessary. ### Additional Tips - Use non-abrasive cleaners to avoid damaging the sink or fixtures. - Check your bathroom sink regularly for any signs of leaks or water damage. - If the leak is significant or you are unsure about how to fix it, call a professional plumber.
