You can try a few safe DIY steps before calling a plumber.
- Plunge the fixture with a sink plunger.
- Remove and clean the P-trap if accessible.
- Run a handheld drain snake to break the blockage.
- Use an enzymatic cleaner like Bio-Clean overnight. Stop and call if multiple drains back up, you smell foul odors, or hear gurgling. Those signs can mean a main sewer issue. We clear severe clogs with rooter service, hydro-jetting, and video camera inspection in Boulder and Denver.
