What Causes a Slow Shower Drain Without a Complete Clog?

A slow shower drain usually means a partial blockage, not a full clog. Common causes include hair and soap scum at the strainer or P-trap, mineral scale narrowing the pipe, or biofilm buildup along the line. If multiple fixtures are slow, the main line may have buildup. We can verify the cause with a FREE video camera inspection and clear it with mechanical snaking or hydro‑jetting as needed.

Quick checks:

• Remove and clean the strainer and P-trap.
• Flush with hot water.
• Note if other drains are slow (possible main line issue).
