Step-by-step walkthrough

Take a photo or note what you find. If a step does not match your property or the symptom gets worse, stop and call for professional guidance.

Check whether one fixture or several are affected
Step 1

Check whether one fixture or several are affected

A single slow sink may be a local trap or branch-line issue. Toilets, tubs, sinks, or a floor drain backing up together point toward a larger line problem.

Check before continuing: Keep the area dry, controlled, and easy to observe.

Try the least aggressive safe step
Step 2

Try the least aggressive safe step

For an isolated, non-sewage slowdown, remove visible debris and use a properly sized plunger. Keep the area ventilated and follow the product label if a chemical was already used.

Check before continuing: Keep the area dry, controlled, and easy to observe.

Look for warning signs
Step 3

Look for warning signs

Gurgling, foul odors, wastewater, recurring backups, or a clog that returns quickly are reasons to stop DIY attempts. Do not open a cleanout if pressure or wastewater may be present.

Check before continuing: Keep the area dry, controlled, and easy to observe.

Share the pattern with a professional
Step 4

Share the pattern with a professional

Tell the technician which fixtures are affected, what was tried, and what the water looked or smelled like. This helps determine whether a camera inspection or cleanout is appropriate.

Check before continuing: Keep the area dry, controlled, and easy to observe.

Know your next step

When the simple check is not enough.

Share the photos, symptoms, and steps you already tried. New Flow Plumbing can help confirm the cause and recommend the appropriate repair path for your home or property.
