Why Sinks Get Clogged in the First Place
Before you try to fix a clogged sink, it’s important to understand what causes it. Sink clogs rarely happen overnight—they build up gradually.
Common causes of sink clogs:
Understanding the cause helps you choose the safest and most effective fix.
First Signs Your Sink Is Getting Clogged
Most sink clogs give warning signs before completely blocking the drain. Watch for:
Addressing these early can prevent a full blockage.
How to Fix a Clogged Sink: Step-by-Step
Step 1: Stop Using the Sink
If water is draining slowly or backing up, stop running water immediately. Continued use can worsen the clog and cause overflows.
Step 2: Try Boiling Water (Best for Grease Clogs)
Boiling water can dissolve grease and soap buildup in kitchen sinks.
How to do it:
- Boil a kettle or pot of water.
- Slowly pour it directly into the drain in stages.
- Wait a few minutes and test drainage.
Avoid this method if you have PVC pipes, as extreme heat may soften joints.
Step 3: Use a Plunger Correctly
A sink plunger can dislodge clogs near the drain opening.
How to plunge a sink properly:
This works best for partial clogs.
A slow drain usually means buildup deeper in your pipes—not just surface debris. Call Dovis Plumbing at (954) 516-1078 to clear the clog before it turns into a full backup.
Step 4: Remove and Clean the P-Trap
The P-trap is the curved pipe under your sink—and a common clog location.
Steps:
- Place a bucket under the trap.
- Unscrew the slip nuts by hand.
- Remove the trap and clear debris.
- Rinse thoroughly and reinstall.
This step often resolves bathroom sink clogs caused by hair and soap.
Step 5: Use a Drain Snake or Hand Auger
If the clog is deeper, a drain snake can break it up.
Best practices:
Avoid long power snakes unless you have experience—they can damage pipes.
Best Tools to Fix a Clogged Sink
