Drain Cleaning – Cedar Hills, Beaverton OR
True Flow Plumbing provides drain cleaning throughout Cedar Hills, Beaverton's oldest established neighborhood. Cedar Hills was built primarily in the 1950s and 1960s, which means the drain lines running under these homes are cast iron pipe that's now 60-plus years old. Cast iron at that age corrodes from the inside, develops rough interior walls that trap grease and debris, and has root systems from the neighborhood's mature trees working on every joint. Recurring clogs in Cedar Hills are not a coincidence — they're what cast iron drain pipe does after six decades in the ground.
Why Cedar Hills Drains Keep Coming Back
The cast iron sewer laterals in Cedar Hills homes were installed when the neighborhood was built — the 1950s and early 1960s. Cast iron is durable pipe, but it corrodes from the inside over time. The corrosion creates a rough, pitted surface on the interior walls that grease, soap scum, and debris cling to. Sixty years of kitchen and bathroom use has built up layers of accumulation that narrows the effective diameter of the pipe and makes it progressively more prone to blockage.
At the same time, the oak, maple, and cedar trees that give Cedar Hills its name have been growing for six decades. Their root systems are fully mature and have been targeting sewer joint connections for years. Roots enter through the joints, grow inside the pipe, and create a debris-catching structure that blocks flow even after snaking cuts them back.

Frequently Asked Questions
My Cedar Hills home had the drain snaked six months ago and it's blocked again. What's going on?
On 60-year-old cast iron, a clog that returns within months after snaking almost always means root intrusion at a joint that regrows after cutting, or corroded pipe walls that immediately begin accumulating debris again after the blockage is cleared. Snaking solves the symptom; a camera and hydro jetting address the cause. At six months, the pipe is telling you something about its condition that snaking alone won't fix.
Do Cedar Hills homes need CIPP lining?
Not automatically — but more Cedar Hills homes are candidates than newer neighborhoods. When the camera shows joint damage that's allowing persistent root intrusion, CIPP lining installs a seamless new structural liner inside the existing cast iron. The old pipe becomes the form for a new interior that roots can't infiltrate. It's a permanent fix for the intrusion problem without excavating the yard. We scope first and tell you whether the pipe condition warrants it.
