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 accumulation that a jetter removes better than a snake, grease or residue narrowing the pipe, a small foreign object lodged in the line, early root intrusion in the main, or a vent pipe blockage. Our plumbers use video camera inspections to pinpoint hidden problems and can repair damaged piping after inspection.

Quick checks:

• Remove and clean the drain strainer for hair.
• Schedule annual professional drain cleaning; larger families may need it more often.
