Sudden drain backups are usually caused by a blockage that has been building for a while, such as grease, hair, wipes, or food scraps, that finally closes the pipe. Foreign objects, tree roots in the sewer line, and a collapsed or sagging pipe can also cause backups that seem to appear overnight.
Buildup That Finally Closes the Pipe
Most drains narrow slowly. Grease cools and sticks to pipe walls, and soap and hair collect in bathroom drains. Water still gets through for a while, so you may not notice. Then one more item catches on the buildup and the drain stops completely.
Things That Should Not Be Flushed
Wipes, even those labeled flushable, do not break apart like toilet paper. Paper towels, cotton swabs, dental floss, and hygiene products also cause clogs. In homes with young children, small toys and other objects can end up in the toilet and block the drain.
Problems in the Sewer Line
If the backup affects more than one fixture, the main line may be the issue. Tree roots can grow into older pipes through small cracks. Pipes can also sag over time, creating low spots where waste collects. Heavy rain can sometimes slow drainage into city sewers as well.
What You Can Do Right Away
- Stop running water in the affected fixtures
- Try a plunger on a single clogged sink or toilet
- Avoid chemical drain cleaners, which can damage pipes
- Do not run the washing machine or dishwasher until it is fixed
If one drain is slow, you may be able to clear it with a plunger. If several are backing up, or the clog keeps returning, clearing the blockage and finding the cause is the safer option. Backups are also a reminder to keep the rest of your drains in good shape with simple habits and occasional service. Call JPR Plumbing at (833) 603-1840.
