Living in beautiful Lake Oswego, Oregon, comes with its perks—tree-lined streets, quiet neighborhoods, and access to some of the cleanest water in the state. But many local homeowners face an all-too-common and frustrating issue: low water pressure. Whether you’re trying to take a shower, run a dishwasher, or water the garden, low pressure can quickly become a daily annoyance.
In this post, we’ll explore the common causes of low water pressure in Lake Oswego homes, how it affects your plumbing system, and most importantly—how you can fix it.
🚿 What Is Considered “Low” Water Pressure?
According to the EPA’s WaterSense program, optimal water pressure in a household should be between 40 to 60 PSI (pounds per square inch). Anything below 40 PSI is considered low and can affect appliance performance and personal comfort.
If you notice:
- Weak flow from faucets
- Long fill times for washing machines or toilets
- Shower heads dribbling instead of spraying
…you’re likely dealing with a water pressure issue.
🔍 Why Lake Oswego Homes Often Experience Low Water Pressure
1. Aging Infrastructure
Some homes in Lake Oswego, especially those built in the 1950s–1970s, may still rely on galvanized steel pipes, which corrode over time. As rust builds up inside the pipes, it reduces internal diameter, restricting water flow.
2. Municipal Water Supply Variables
Lake Oswego receives its water from the Clackamas River through the Lake Oswego-Tigard Water Partnership. During periods of high demand or maintenance, pressure may dip temporarily. If your neighbors also experience pressure issues, the problem may be on the city’s end.
3. Pressure-Reducing Valves (PRVs)
Most modern homes have a pressure-reducing valve installed at the main water line. If this device malfunctions or is improperly set, it can cause widespread low pressure throughout the home.
4. Clogged Fixtures or Aerators
Sometimes, the issue is hyper-local—just one bathroom sink or one shower head. In that case, buildup of mineral deposits (especially if your home has hard water) may be the culprit.
Tip: Unscrew faucet aerators and clean them every 6–12 months to improve flow.
5. Hidden Leaks
A water leak in the slab, basement, or walls can silently reduce your pressure and raise your water bill. Keep an eye out for:
- Unexplained dampness
- Spiking utility costs
- Hissing or dripping sounds behind walls
🛠️ How to Fix Low Water Pressure in Your Lake Oswego Home
✅ 1. Check Your PRV and Main Shut-Off Valve
Ensure your main shut-off valve is fully open. Then, locate your PRV—usually found where the main line enters the home—and adjust it. If you’re unsure, it’s best to call a licensed plumber.

✅ 2. Inspect Fixtures and Aerators
Remove and clean aerators and shower heads using a vinegar soak to remove mineral buildup. If fixtures are outdated, consider upgrading to WaterSense-labeled products, which are designed for both efficiency and consistent pressure.

✅ 3. Repipe with PEX or Copper
If corroded galvanized pipes are the issue, it might be time for a whole-house repipe using PEX or copper. This is especially recommended for homes older than 50 years.
✅ 4. Install a Booster Pump
For homes at higher elevation or at the end of the city water line, a pressure booster pump can dramatically improve flow. These systems are compact, efficient, and customizable to your home’s needs.
✅ 5. Schedule a Full Plumbing Inspection
Still not sure what’s causing the issue? A professional plumbing inspection from a trusted local expert will help identify the root cause—whether it’s underground leaks, municipal pressure changes, or aging hardware.
