Drain cleaning and sewer service in Tigard, Oregon
Tigard is a compact, largely 1970s–1990s suburb built across rolling terrain, and that topography matters more than its age. Homes on the low side of a slope inherit their uphill neighbours' groundwater, and the resulting crawlspace and sump problems are the most common drain problems here.

What goes wrong with Tigard plumbing
Downslope groundwater accumulation
Tigard's rolling terrain over clay concentrates winter groundwater at the bottom of each slope. Homes in those positions run sump pumps continuously from November to March, and pump failure here means water in the crawlspace within hours rather than days.
ABS pipe fittings from the 1970s
Some 1970s ABS installations used solvent-weld fittings that have become brittle. The failure shows up as a leak at a joint rather than a clog, often discovered only when a crawlspace inspection finds long-standing moisture.
Fanno Creek floodplain properties
Properties near Fanno Creek and its tributaries deal with a seasonally high water table that drives lateral infiltration and puts sustained demand on sump systems.
Housing stock and pipe materials
Housing: Overwhelmingly 1970 onward, with a small older core near downtown Tigard and Main Street.
Likely pipe materials: ABS and cast iron on 1970s stock, PVC from the 1980s on.

Tigard plumbing questions
Why does my Tigard sump pump run constantly in winter?
Tigard's rolling terrain over clay concentrates groundwater at the bottom of each slope, so if you are on the low side of a hill you are receiving your uphill neighbours' water as well as your own. Continuous winter running is normal here. Continuous running in dry summer weather is not, and usually means a failed check valve letting discharge water fall back into the basin.
I have a leak but no clog — what is going on?
On 1970s Tigard homes this is frequently a solvent-weld ABS fitting that has become brittle with age. It leaks at the joint rather than blocking flow, so there is no drainage symptom at all and it is often discovered only when someone finally looks in the crawlspace and finds long-standing moisture.
Are properties near Fanno Creek higher risk?
Yes, for groundwater rather than pipe condition. The Fanno Creek corridor and its tributaries carry a seasonally high water table, which drives infiltration into any lateral with open joints and puts sustained load on sump systems. It does not make your pipe fail faster, but it makes an existing defect matter much sooner.
