How to Prevent Clogged Drains — A Room-by-Room Guide

Washing machine drains see lint, detergent residue, and occasionally small items that slip through pockets. Over time, detergent buildup — especially from powder detergent or fabric softener — can coat the inside of a standpipe drain the same way grease coats a kitchen line.

• ✓Clean the washing machine’s lint filter or trap regularly if it has one
• ✓Switch to liquid detergent if you notice slow laundry drainage, since powder residue builds up more
• ✓Check pockets before washing to keep small items out of the drain line

Exterior drains and the sewer lateral running from your home to the street face a different set of risks — leaves and yard debris in surface drains, and tree root intrusion in the sewer line itself. Mature trees common in older Miami neighborhoods send roots toward the moisture inside sewer laterals, entering through small cracks or joint separations in aging clay or cast-iron pipe.

• ✓Keep outdoor drain grates clear of leaves and yard debris, especially before storms
• ✓Be mindful of where large trees are planted relative to your sewer lateral
• ✓If you have mature trees and a history of slow drains, ask about an annual hydro-jet cleaning

Good habits prevent most single-fixture clogs, but recurring clogs, multiple slow drains at once, or gurgling from one fixture when another is used usually point to something prevention alone can’t fix — often a main line issue that needs professional drain cleaning or a camera inspection to diagnose properly.
