Drain Cleaning – Metzger, Tigard OR
True Flow Plumbing provides drain cleaning throughout Metzger in unincorporated Washington County. Metzger's 1950s and 1960s homes have cast iron drain lines inside the house that are 60 to 70 years old — interior corrosion has been reducing the usable diameter for decades, creating rough walls that catch grease and paper much more readily than new pipe. The sewer lateral in the yard is typically clay tile with open bell-and-spigot joints: the preferred entry point for mature tree roots. We camera before we clear, because knowing what you're dealing with changes the right approach entirely.
Cast Iron Interior Corrosion — Why Metzger Drains Get Slow Over Time
Cast iron from the 1950s and 1960s is vulnerable to internal oxidation over decades of use. The interior surface roughens and gradually narrows — grease and soap deposits stick to the corroded walls faster than they would in smooth new pipe. The result is a drain that gets slower and more clog-prone over time even with no single dramatic blockage event. The camera shows remaining interior diameter and whether clearing will help or whether the pipe's working life has reached its natural end.
Warning Signs
- Multiple drains slowing at the same time
- Clogs recurring at the same spot
- Main line backup — water backing up at floor drains or tub
- Gurgling from the toilet when other fixtures drain
- Sewage odor from a cleanout or drain
- Drains getting progressively slower despite regular clearing

Frequently Asked Questions
My Metzger drain clears fine with a snake but backs up again in a few weeks. Why?
On cast iron this age, that pattern typically means interior corrosion has created a restriction that catches debris faster than smooth pipe would. The snake punches through the accumulated clog — but doesn't restore the interior diameter or surface smoothness that was there 40 years ago. The camera shows how much restriction exists and whether hydro jetting will meaningfully restore flow or whether the pipe is at the end of its useful life.
