Marylhurst is a riverfront community on OR-43 between Lake Oswego and West Linn, home to the former Marylhurst University campus. Most of it was annexed into the City of Lake Oswego, so the great majority of homes are on Lake Oswego city water and sewer, though a few fringe riverfront parcels may remain unincorporated. The housing is a mix of mid-century homes near the old campus, newer infill, and high-end riverfront and hillside estates along the Willamette.
What this means for emergency plumbing in Marylhurst. In the pre-1970 homes we pull galvanized-steel supply — failing here from age, not hard water, since the city water is soft — plus cast-iron and clay laterals. The 1978-1995 homes carry polybutylene (PB) that splits without warning, and copper of any era can develop pinhole leaks. The estates bring multi-bath, tankless, and backflow complexity. Along the river, the high water table drives sump and backwater work.
We work the Marylhurst, Lake Oswego, and West Linn corridor regularly — and it’s one of our closest service areas. Stocked trucks carry PB-to-PEX transition fittings, copper repair couplings, battery-backup sump pumps and backwater valves, no-hub couplings, common Bradford White and AO Smith water heaters for same-day swap, and a full hydro-jet-and-camera kit for the hillside laterals.

The neighborhoods around the former Marylhurst University campus and Our Lady of the Lake — mid-century homes, galvanized and polybutylene supply. We cover all of it, live 24/7.
The riverfront estates and low lots along the Willamette — high water table, sump-pump load, and backwater-valve needs.
The hillside lots along Highway 43 — long, steep sewer laterals prone to root intrusion and offsets, any hour.
The Glenmorrie-area homes toward Lake Oswego — a mix of city-served and legacy-septic lots, any hour, day or night.
The wooded lots near Mary S. Young State Park toward West Linn — riverfront high groundwater and hillside laterals.
The high-end multi-bath homes on the slopes — tankless, pressure-zone, and backflow complexity, plus copper pinhole leaks.
Most of Marylhurst is annexed into Lake Oswego, so city water comes from the Lake Oswego system — sourced from the Clackamas River and treated at the Lake Oswego–Tigard plant in West Linn — and it is soft (around 25 ppm), so galvanized-pipe failures here are age-driven, not hard-water scale. Sewer is Lake Oswego sanitary for annexed parcels; the area was historically on septic, and failing septics drove much of the annexation, so a few legacy septic systems may persist on unsewered riverfront or hillside lots. Any truly unincorporated parcel falls to Clackamas County and the regional Tri-City treatment system. We service city-water, sewer, and legacy-septic properties.
Because most Marylhurst parcels are inside Lake Oswego, plumbing permits go through the City of Lake Oswego Building Division (380 A Avenue, 503-635-0290) via Oregon’s ePermitting (Accela) portal; any unincorporated riverfront pocket falls to the Clackamas County Building Codes Division (503-742-4240). Under Oregon’s emergency-repair rule (OAR 918-780-0035) a licensed plumber can repair freeze-damaged or leaking pipe up to 5 feet of new pipe per structure without a permit; beyond 5 feet, and for water-heater swaps and underground work, a permit is required.
Stocked trucks dispatched from SE Portland for all of 97036.
Sump Pump & Riverfront Flood Plumbing. The Willamette riverfront and low lots carry a high water table in the wet season, pushing water into crawlspaces and basements. We install and repair battery-backup sump pumps and backwater valves — the standard protection for riverfront Marylhurst homes.
Sewer Line & Hillside Laterals. The steep OR-43 hillside lots run long downhill sewer laterals that belly and draw roots, and older sections have clay and cast-iron lines. We camera-scope first, then hydro-jet, spot-repair, or trenchless-line the lateral.
Burst Pipe & Repipe. Galvanized end-of-life in the pre-1970 homes (age-driven, not hard water), polybutylene fitting failures in the 1978-1995 stock, and copper pinhole leaks. We isolate the leak, restore water, and lay out a repipe scope to PEX or copper.
Leak Detection. Acoustic, thermal-imaging, and pressure-isolation testing find hidden slab, wall, and concealed copper-pinhole leaks in the estates without random tear-out. We open as little as possible.
Water Heater & Fixture Service. Tank and tankless — common 40- and 50-gallon Bradford White, AO Smith, and Rheem units stocked for same-day swap; Rinnai and Navien tankless — plus pressure-regulator, backflow, and multi-bath fixture work for the estate homes.

Replacement of concealed piping exceeding 5 ft requires a permit; under Oregon’s emergency rule a licensed plumber can repair freeze-damaged or leaking pipe up to 5 ft of new pipe right away.
