Why Gresham homes need these repairs

Gresham is Portland's eastern neighbor, with many 1960s–90s homes and apartments. In 2026 it switched its main supply from Portland's Bull Run water to its own deep Cascade groundwater wells, and wet winters, older laterals and crawlspace moisture drive most calls.

Gresham's water supply and your plumbing

In spring 2026 Gresham switched its primary source from Bull Run water to Cascade Groundwater, keeping Bull Run and Columbia South Shore water as backups. [1]

Nine wells pump water from the Sand and Gravel Aquifer more than 600 feet below ground, the oldest and deepest aquifer in the Portland basin. [2]

Polybutylene-era homes in Gresham: leaks and repiping

The median home in Gresham was built in 1982, and 46% of homes predate 1980. Homes from that era were typically built with copper or CPVC supply, plastic drains, and in some homes gray polybutylene supply pipe, which is where leaks, low pressure and drain problems usually start as they age.

Median home: 1982
1900195020002025
  • Galvanized steel supply (1900–1960)
  • Copper supply (1950–2000)
  • Polybutylene (some homes) (1978–1996)
  • PEX / CPVC (1995–today)
Typical supply-pipe materials by construction year. Many older homes have been partly repiped since.

Gresham plumbing questions

Can recurring clogs in Gresham mean a sewer line problem?

Yes. When several drains back up together, the main sewer line is the likely cause, and a camera inspection shows whether it's roots, a sag or a break. Why it comes up in Gresham: Older laterals under big trees crack and take in roots.

When is a leaking water heater an emergency in Gresham?

A leak from the tank itself won't stop and usually means replacement; turn off the gas or power and the cold-water valve, then call. Why it comes up in Gresham: Tanks in 1970s–90s homes reach end of life.

Did Gresham stop using Bull Run water?

As its main source, yes. Since spring 2026 Gresham relies on Cascade groundwater, with Bull Run as a backup.

Will Gresham's groundwater change my plumbing?

Groundwater is a bit harder than Bull Run water, so you may notice more spotting; most homes don't need changes.

Is Rockwood on Gresham water?

Rockwood Water PUD serves part of the area and partners with Gresham in the Cascade Groundwater Alliance. Your bill names the provider.

Why is my Gresham crawlspace damp every winter?

Heavy rain raises groundwater. A sump and good drainage keep water off pipes and insulation.
