Common Clogged Drain Scenarios
Stop Using the Drain
Running more water into a clogged drain can cause overflow. Stop all water use in the affected area until the clog is cleared.
Try a Plunger First
A cup plunger (not a flange plunger) works for sinks. Create a seal and plunge firmly 10-15 times. If it doesn't clear in 3 attempts, call a pro.
Skip the Chemical Drain Cleaners
Chemical drain cleaners (Drano, Liquid-Plumr) can corrode pipes and are hazardous. A plumber's snake or hydro-jet is safer and more effective.
Check Other Drains
If multiple drains are slow or backing up, the clog is in the main sewer line — not a single fixture. This is more urgent and needs professional attention.
Frequently Asked Questions
When should I call a plumber for a clogged drain?
Call a plumber if: the plunger doesn't work after 3 attempts, multiple drains are slow at once, water is backing up (not just slow), or you've had recurring clogs in the same drain. Most drain cleaning pros in Rockville can come same-day.
What causes clogged drains?
Common causes: hair and soap in bathroom drains, grease and food in kitchen drains, tree roots in main sewer lines, and mineral buildup in older pipes. In Rockville homes with mature trees, root intrusion is a frequent cause of main line clogs.
How much does it cost to fix a clogged drain in Rockville?
Drain unclogging in Rockville costs $150-$450 depending on location and severity. Kitchen and bathroom drain clogs are on the lower end. Main sewer line clogs requiring camera inspection and hydro-jetting cost $350-$900.
Can a clogged drain damage my home?
Yes — a clogged drain that causes backup can lead to water damage, mold growth, and sewage contamination. A main sewer line backup in your Rockville home is a health hazard. Don't delay getting it cleared.
