Drain Cleaning – Bethany, Beaverton OR
True Flow Plumbing provides drain cleaning throughout Bethany, the hillside community on Beaverton's northwest edge. Bethany homes from the 1990s and early 2000s have PVC drain lines — more durable than the cast iron in Cedar Hills or ABS in Oak Hills, but that doesn't mean drain-problem-free. Bethany's lots were carved out of hillside land with established Douglas fir cover, and those root systems didn't stop growing when the neighborhood was built. Twenty to thirty years later, fir roots have worked their way to lateral joints throughout the neighborhood. That — not pipe material failure — is the main driver of recurring drain problems in Bethany.
The Douglas Fir Root Problem in Bethany
When Bethany's hillside subdivisions were graded in the 1990s, some of the existing Douglas fir stand was cleared and some was retained — on property lines, in greenways, and on neighboring lots. Douglas fir root systems extend well beyond the drip line of the tree and continue growing aggressively after the tree is established. Those roots find moisture sources, and sewer lateral joints are exactly what they're looking for.
Warning Signs
- Main line backing up — all fixtures slow or gurgling at the same time
- Toilet bubbling when the washer drains or the tub is used
- Kitchen sink draining slowly despite no obvious clog
- Sewage odor in the yard, especially near the lateral route
- A clog that was cleared a few months ago and has returned
- Slow drains in a home that's only 20–30 years old — the house isn't too old, but the trees are

Frequently Asked Questions
My Bethany home is only from 2001. Why do I keep having drain problems?
The home is 20-plus years old — newer than Cedar Hills but not new. More importantly, the Douglas fir root systems around Bethany's hillside lots have had 20-plus years to extend toward your lateral. PVC is a great pipe material, but joint connections are still the vulnerable point. A camera inspection will show you exactly where the intrusion is entering and how much of the pipe is affected.
Do you serve the hillside streets in Bethany?
Yes — all of the Bethany hillside subdivisions including the streets along Springville Road, NW 185th, and the residential streets throughout the Bethany community. We also serve Cedar Mill, Oak Hills, and all surrounding northwest Beaverton neighborhoods.
Can CIPP lining fix root intrusion permanently?
Yes — for the joints that are lined. CIPP installs a seamless structural liner inside the existing PVC that covers and seals the joint. Roots can no longer enter at that point. It's the permanent solution for recurring root intrusion without excavating the yard or replacing the pipe.
