Spring in Sacramento is a beautiful time of year. The days get longer, the flowers bloom, and our iconic Valley Oaks and London Plane trees start waking up from their winter slumber. But while we enjoy the greenery, something is happening underground that could be wreaking havoc on your plumbing.
As the soil begins to dry out from our limited winter rains, tree roots go searching for moisture. Unfortunately, the warm, moist environment inside your sewer line is the perfect target. If you have large trees like Valley Oaks, Interior Live Oaks, or London Plane trees near your property line, your pipes might be in the crosshairs.
Here is what you need to know about spring root intrusion and how to spot the trouble before it becomes a major mess.
Why March Is "Root Season"
During the winter, soil is usually damp, so roots stay plump and happy where they are. But as March arrives and the ground starts to dry, roots grow aggressively toward any source of water. They are drawn to the vapor escaping from tiny cracks in your aging clay or cast iron pipes. Once they find a small gap, they force their way inside. Over time, those hair-like roots expand into dense mats that catch debris and block waste.
3 Warning Signs Your Sewer Line is Fighting Tree Roots
Because these intrusions happen slowly underground, you might not notice them until they cause a backup. Based on what we see in Sacramento homes every spring, here are the top indicators that roots have invaded your line:
- Gurgling Toilets: If you flush the toilet and it responds with a strange bubbling sound, that means air is trapped in the line due to a blockage downstream.
- Slow-Moving Drains: This is usually the first sign. If your sink takes forever to empty, or if your shower water lingers around your ankles, it’s often a sign that the main line is struggling to push water past the root mass.
- Water Backing Up: This is probably the most alarming sign. If you flush the toilet and water rises in the shower drain or another tub, your sewer line is likely clogged. This is a critical moment where you need professional help immediately to prevent a home-wide backup.
What To Do (And Not Do)
If you notice these signs, please do not reach for a chemical drain cleaner. Pouring harsh chemicals down a slow drain can actually kill the roots inside the pipe, but it leaves a dead, mushy mass that can still cause a clog; not to mention that it’s terrible for the environment.
A professional video camera inspection is the best way to confirm root intrusion. We can snake the line to see exactly where the roots are and whether they have cracked the pipe.
Can You Prevent Roots in Sewer Lines?
While you can't control where a 100-year-old Valley Oak grows, you can be proactive:
- Schedule a Spring Inspection: March is the perfect time for a routine sewer scope. Catching roots early means we can often cut them away before they cause a complete backup.
- Be Mindful of Planting: If you are landscaping, avoid planting water-loving trees like willows or London Plane trees directly over your sewer lateral.
