Toilet Drain Clogged? Here’s What Might Be Causing It

An open toilet bowl

If your toilet isn’t flushing with the same power it used to—or worse, not flushing at all—you’re likely dealing with a clog. While some blockages are easy to clear, others may point to a more serious problem with your plumbing system.

At Radiant, we’ve seen (and cleared) just about every kind of clog out there. Here are the most common reasons your toilet drain might be clogged—and when it’s time to call in a pro.

Common Causes of Toilet Drain Clogs

1. Too Much Toilet Paper

Toilet paper is one of the most common reasons drains get clogged. Modern brands are thicker and more durable, which is great for comfort—but not always ideal for older or narrow sewer lines. Over time, paper can build up and create a blockage that water simply can’t push through.

2. Tree Root Intrusion

One often-overlooked cause of toilet clogs is tree roots. Roots naturally seek out moisture and can infiltrate your sewer line through even the tiniest crack. As they grow, they expand the damage—eventually forming a major obstruction that slows or completely blocks drainage.

For this kind of clog, professional equipment is required. Hydro jetting, which uses high-pressure water to blast through roots and buildup, is one of the most effective solutions.

Don’t Let a Toilet Clog Disrupt Your Day

If your toilet isn’t flushing properly, don’t wait for it to turn into a backup emergency. Whether it’s a buildup of paper or a root-related obstruction, Radiant’s licensed plumbers can diagnose the issue and clear the line safely and thoroughly.
