A clogged drain disrupts your entire routine — standing water in the kitchen sink, a shower that won't drain, a toilet that won't flush. STL Plumbing Pros diagnoses the blockage location and clears it completely using professional cable machines and hydro jetting. For recurring clogs, a camera inspection reveals the root cause. We don't just punch a hole through the clog — we remove the buildup so it doesn't come back next month.
Common Clogged Drain Symptoms
Water pools in the sink or tub and drains very slowly — taking minutes instead of seconds.
Toilet flushes weakly or won't flush at all — water rises instead of draining.
Gurgling sounds from nearby drains when you flush a toilet or run a faucet.
Water backs up from floor drains in the basement during heavy water use.
Foul odor from drains — decomposing organic matter trapped in the line.
What Causes Clogged Drains in St. Louis?
Hair & Soap Buildup
Bathroom drains accumulate hair, soap scum, and body oils. The combination creates dense, sticky clogs that plunging alone can't clear.
Grease & Food Waste
Kitchen grease solidifies inside drain pipes. Even small amounts accumulate over months, eventually restricting the pipe diameter enough to cause backups.
Tree Root Intrusion
St. Louis's mature tree canopy means roots seek moisture in clay sewer pipes. Root intrusion is the #1 cause of main line clogs in older neighborhoods.
Pipe Scale & Corrosion
Older galvanized and cast iron pipes develop interior scale that catches debris. The rough interior surface accelerates clog formation compared to smooth PVC.
Our Clog Repair Process
Locate the Blockage
We determine whether the clog is in the fixture trap, branch line, or main sewer. This determines the right equipment and approach.
Clear Completely
Using the appropriate cable size and technique, we remove the blockage entirely. For grease or roots, hydro jetting scours the pipe walls clean.
Verify and Prevent
We test flow at full volume, check for secondary issues, and recommend preventive steps — whether that's a drain screen, regular maintenance, or a pipe repair.
