Slow-draining shower

What this symptom usually tells you

The most useful clue is whether the problem is isolated or appears elsewhere. Mechanical hair removal is normally the clearest first step because it extracts rather than disperses the obstruction.

• Lift and clean the removable cover
• Check the basin and bath
• Listen for gurgling
• Note how quickly the tray fills

Choose the next step, not the strongest option

Start with visible debris and the least aggressive suitable manual method. A repeat blockage, sewage backup or several affected fixtures needs diagnosis rather than another product.

• Check every nearby fixture
• Identify anything already poured into the drain
• Keep a note of gurgling, odour and water-level changes
• Stop before wastewater overflows
