Every homeowner has dealt with a slow or clogged drain at some point. While a plunger or drain cleaner may provide temporary relief, recurring clogs are often a sign of a bigger plumbing issue. Understanding what causes your drains to clog can help you avoid costly repairs and keep your plumbing system flowing properly.
1. Hair Buildup
Hair is one of the biggest causes of bathroom drain clogs. Over time, hair combines with soap residue and forms thick blockages inside the pipes.
Prevention Tip:
- Install a hair catcher over shower and sink drains.
- Clean the catcher weekly.
2. Grease and Cooking Oil
Many homeowners pour grease down the kitchen sink, thinking hot water will wash it away. Unfortunately, grease cools and hardens inside your pipes, trapping food particles and creating stubborn blockages.
Never Pour Down the Drain:
- Bacon grease
- Cooking oil
- Butter
- Fat from meats
Instead, allow grease to cool and dispose of it in the trash.
3. Soap Scum
Traditional bar soaps contain fats that combine with minerals in water, creating soap scum that coats the inside of your plumbing.
Over time, this narrows the pipe and slows water flow.
4. "Flushable" Wipes
Despite the label, most flushable wipes do not break down like toilet paper. They frequently become lodged in sewer lines and are one of the leading causes of residential sewer backups.
Only flush:
- Toilet paper
- Human waste
Everything else belongs in the trash.
5. Tree Root Intrusion
Tree roots naturally seek moisture and can invade tiny cracks in underground sewer pipes. Once inside, the roots continue growing and eventually block the entire sewer line.
Warning signs include:
- Multiple drains backing up
- Gurgling toilets
- Sewage odors
- Water backing up into tubs or showers
6. Mineral Buildup
Homes with hard water often experience mineral deposits that slowly build inside water lines and drains.
These deposits reduce water flow and increase the likelihood of recurring clogs.
7. Broken or Collapsed Pipes
Older plumbing systems can develop cracks, offsets, or collapsed sections that catch debris and repeatedly clog.
A professional sewer camera inspection can quickly identify these hidden problems without unnecessary digging.
