Why is my sink draining slowly even after cleaning the trap?
If your sink still drains slowly after cleaning the P-trap, the blockage is likely farther down the branch line or the vent is restricted. A stuck or misaligned pop-up, a sludge-filled disposal, or buildup and corrosion in older pipes can also reduce flow. Homes in Novato and nearby areas often need a plumber to snake the line and reset components to restore proper drainage.
Quick checks:
- Run the disposal with cold water.
- Remove and clean the pop-up and drain arm.
- Listen for gurgling, which suggests a vent issue.
Quick checks:
- Check the shut-off valves for leaks or incomplete closure.
- Look for rust or corrosion at the faucet and supply connections.
- Note squeaking handles or pressure swings when turning the tap.
