Drain Cleaning – Bull Mountain, Tigard OR
True Flow Plumbing provides drain cleaning throughout Bull Mountain in Tigard. Bull Mountain's 1980s and 1990s hillside homes have ABS and PVC drain lines that are 25 to 40 years old — on sloped lots, those lines are subject to pipe belly as hillside soil shifts over time. Combined with 30-plus years of grease accumulation inside the pipe and maturing landscape trees finding lateral joints, drain problems on Bull Mountain often have a specific cause that a camera identifies before any clearing starts. We find the cause first.
Hillside Pipe Belly: Bull Mountain's Most Common Recurring Drain Cause
As soil shifts on Bull Mountain's sloped lots over 30 to 40 years, sections of sewer lateral sag slightly below intended grade. Debris and water pool in the low spot instead of flowing through. A snake clears the accumulated debris — flow returns, debris builds up again in the same low spot, and the cycle repeats at a predictable interval. The camera locates the belly and confirms how significant it is. Targeted repair of the sagged section is the permanent fix.

Frequently Asked Questions
My Bull Mountain drain backs up every few months, gets cleared, then backs up again. What's causing it?
That pattern — recurring backup on a predictable cycle — points to either pipe belly or root intrusion. Both allow debris to accumulate in the same spot repeatedly. A snake clears it; the low spot or the root mass catches debris again the next season or two. The camera tells you which it is and where, so the fix addresses the actual problem rather than just reopening the pipe until next time.
