Common drain clog warning signs
Sluggish drainage, unpleasant smells and unusual sounds are useful warning signs to report. A sink that empties more slowly than before may need attention even if it has not fully stopped. Describe when the behavior started and whether the problem changes as other fixtures are used.
If wastewater is backing up or a fixture is overflowing, stop adding water through the affected fixture and contact the team. Do not keep testing an overflowing drain. Tell us whether one fixture is involved or several, because the visible location alone does not establish where the restriction sits.
