How to Prevent Common Kitchen and Sewer Clogs

Small habits can prevent many blocked lines. Learn what belongs in the drain and when slow flow needs professional attention.

Keep the wrong materials out

Kitchen grease cools and sticks to pipe walls. Food particles then collect on that layer until the opening narrows. Pour cooled grease into a container for disposal and scrape plates before washing them.

Toilets are designed for human waste and toilet paper. Wipes, paper towel, hygiene products and other household items can catch in the line even when packaging describes them as flushable.

  • Use sink strainers for food and hair
  • Keep grease and oil out of kitchen drains
  • Flush only waste and toilet paper
  • Address recurring slow flow instead of repeatedly using chemical cleaners

Watch for main-line warning signs

One slow fixture often points to a local branch. Several fixtures slowing or gurgling at the same time can indicate a problem farther along the system. Water appearing at a floor drain when another fixture empties is another reason to stop and investigate.

Clearing versus repairing

Many blockages can be mechanically cleared. A damaged, shifted or collapsed line is different: clearing may only provide temporary relief. The right next step depends on where the restriction is and the condition of the pipe.
