Common Causes of Clogged Drains
Almost every clogged drain has a specific, identifiable cause. Knowing the common culprits makes it easier to prevent the next one.
Kitchen Drains
- Grease and cooking oil that solidifies inside the pipe
- Food scraps, especially starchy or fibrous foods that expand or tangle
- Coffee grounds, which don’t break down and build up over time
Bathroom Drains
- Hair, the single most common bathroom clog cause
- Soap scum buildup narrowing the pipe over time
- Small objects accidentally dropped into the drain
Main Line Clogs
- Tree root intrusion in older sewer lines
- A buildup of years of smaller debris finally restricting flow
- Structural pipe damage creating a spot where debris catches
Prevention Tips
- Use drain covers to catch hair and food debris
- Avoid pouring grease down the drain, let it cool and throw it away instead
- Run hot water after using the kitchen sink to help clear residue
- Get main lines professionally cleaned periodically, especially with mature trees nearby

Why do drains keep clogging?
A recurring clog usually means material remains in the line, the wrong cleaning method was used, habits keep reintroducing debris, or the pipe has a defect such as poor slope, corrosion, offset joints, root entry, or a belly.
Homes with long runs, older materials, mature trees, septic connections, or remodeled kitchens and bathrooms around Grants Pass may need a different approach than a simple fixture trap cleaning.
