Why Your West Linn Home Has Low Water Pressure—And How to Fix It

Low water pressure in your West Linn home can be frustrating—whether it’s a trickle in the shower or a slow-filling washing machine. This seemingly small issue could point to deeper plumbing problems. In this guide, we’ll explore why water pressure dropshow to identify the cause, and how to fix it, so you can restore proper water flow and protect your plumbing system long-term.


🚿 Common Causes of Low Water Pressure in West Linn

There are a variety of factors that can contribute to reduced water pressure in homes across West Linn. Here are the most common:

1. Old or Corroded Pipes

Many homes in West Linn were built decades ago and may still rely on galvanized steel pipes. Over time, these pipes corrode internally, restricting water flow.

⚠️ Tip: Corroded pipes may also affect water color and taste. If your water looks rusty or smells metallic, it’s time to inspect your plumbing.

2. Partially Closed Shut-Off Valves

Sometimes, a shut-off valve is not fully opened after repairs, restricting pressure throughout the house.

3. Clogged Faucet Aerators or Showerheads

Mineral deposits from Oregon’s water supply—especially in homes with hard water—can clog aerators and showerheads, reducing flow at specific fixtures.

4. Leaking or Broken Pipes

Hidden leaks reduce water pressure significantly and can cause costly water damage if not addressed early.

5. Faulty Pressure Regulator

Homes with pressure regulators may experience sudden drops in pressure if the regulator malfunctions.

6. Municipal Water Supply Issues

Sometimes, the issue isn’t your plumbing. The City of West Linn’s water supply system may undergo maintenance or experience temporary drops in pressure.


🔍 How to Diagnose Low Water Pressure

Step 1: Check Multiple Fixtures

Is the issue isolated to one sink or shower? If yes, the fixture may be clogged. If pressure is low throughout your home, the problem is likely within the plumbing system.

Step 2: Inspect the Main Shut-Off Valve

Make sure the main valve is fully open. It’s typically located near your water meter or where the main line enters your home.

Step 3: Use a Pressure Gauge

Install a water pressure gauge on an outdoor spigot. Ideal home water pressure ranges between 40–60 PSI. Anything below 40 PSI may indicate a systemic issue.

Step 4: Look for Signs of Leaks

Inspect ceilings, basements, and under sinks for damp spots, mildew, or unexpected water usage spikes.
