What causes drain problems in California?
California's climate is mostly dry summers and wet winters, though it varies widely from the foggy coast to the Central Valley and the mountains. Winter storms are when root-damaged laterals most often back up.
Expansive clay soils in parts of the state, along with seismic activity, can crack or offset buried pipe over time.
Many established neighborhoods still have original clay or cast-iron sewer laterals, and several cities and districts have rules requiring lateral inspection or repair at certain times, such as a home sale. Check local requirements.
Older homes may still have original sewer laterals, and many cities have specific rules for lateral inspection or repair. Hillside lots can mean long or steep sewer runs.
Which drain problems are most common in California?
- Root intrusion in clay sewer laterals.
- Cracked or offset pipe from ground movement.
- Grease clogs in kitchen lines.
- Slow drains from aging cast-iron pipe.
- Main line backups during heavy winter rain.
Which drain services can you reach in California?
Through one call, California residents can reach independent providers for drain cleaning, main line clearing, sewer line cleaning and repair, kitchen sink drains, bathroom, shower and toilet drains, hydro jetting, camera inspection, emergency drain cleaning. If several fixtures are backing up at once, start with main line clearing and stop using water until it's done.
Pro tipIf your main line clogs more than once a year, ask for a camera inspection. It shows whether roots, a sag or damaged pipe is the real cause.
When do drain problems peak in California?
In California, the first big rains of the wet season are a common time for backups, as water enters cracked laterals and roots that grew during the dry months. Watching for early warning signs, such as slow drains, gurgling toilets or water rising in a tub when you flush, gives you time to schedule a visit before a full backup.
What can California homeowners check before calling?
A few minutes of checking can save a visit or make it faster. Lift out pop-up stoppers and clear hair, plunge sinks and toilets with a good seal, and look for your sewer cleanout so the technician can find it quickly. Avoid renting a large drain machine for a main line, which can injure hands and arms or get stuck in the pipe.
What should you have ready when you call?
Before you call, note which drains are affected, whether water is backing up anywhere, roughly how old the home is and where the sewer cleanout is, if you know. Mention any chemical drain cleaner you've used and whether the home is on public sewer or a septic system.
