Lake Oswego, known for its scenic beauty, lush greenery, and serene lakeside views, is no stranger to rain. In fact, the region experiences an average of over 150 rainy days per year, according to the NOAA Climate Data for Portland. While residents may be accustomed to the damp climate, what many don’t realize is just how much Lake Oswego’s rainy weather impacts their home’s plumbing systems.
Whether it’s hidden leaks, sewer backups, or foundational erosion, the moisture-heavy environment can accelerate plumbing issues—leading to costly repairs if not properly addressed.
Here’s a deep dive into how Lake Oswego’s climate can wreak havoc on your plumbing and what you can do to protect your home.
☔ 1. Increased Risk of Sewer Backups
One of the most serious effects of prolonged rainfall is sewer system overflows. During heavy rainstorms, stormwater runoff can overwhelm the municipal sewer system, causing backups into homes—especially those with basement plumbing.
Older homes in Lake Oswego, particularly those built before the 1980s, are more vulnerable due to aged piping and combined sewer systems.
Prevention Tip:
Consider installing a backwater valve to prevent wastewater from reversing into your home. If you’ve experienced slow drains or gurgling toilets during storms, it’s time to schedule a sewer camera inspection with Einstein Pros Lake Oswego.
🌧️ 2. Foundation Shifts That Damage Pipes
The ground beneath your home absorbs rainwater like a sponge. When rainfall is excessive or prolonged, this can lead to soil expansion and shifting—especially in areas with clay-heavy soil, which is common in parts of Clackamas County.
This soil movement puts stress on your underground plumbing pipes, leading to cracks, joint misalignment, or even ruptures. Over time, this can cause slab leaks, hidden water damage, or unexplained high water bills.
Solution:
Invest in annual plumbing inspections and request a pressure test for your main water line if you suspect shifting may be an issue.
💦 3. Rain-Induced Basement Flooding and Sump Pump Failures
Basements are particularly vulnerable to water intrusion in Lake Oswego. A sudden downpour or slow, persistent rainfall can overwhelm sump pumps and seep into walls through microcracks, flooding the basement and causing mold growth, insulation damage, and plumbing corrosion.
If your home relies on a sump pump, be sure it’s capable of handling high-capacity drainage and has a battery backup system in case of power outages during storms.
Pro Tip:
Don’t wait for disaster to strike. Schedule a sump pump inspection or replacement with Einstein Pros before the next rainy season hits.
🪠 4. Clogged Outdoor Drains and Gutter Systems
Leaves, mud, and debris easily clog outdoor drains during fall and winter storms. If water can’t properly flow away from your home, it can pool around the foundation and seep into plumbing vent stacks or crawl spaces, leading to unseen rot and pipe decay.
Make sure your home’s storm drainage system is free from obstructions, and regularly clean gutters, downspouts, and area drains. Don’t overlook French drains or dry wells either, which may require maintenance after years of rainfall impact.
🧼 5. More Moisture Means More Mold (And Plumbing Can Be a Source)
Leaky pipes—especially in walls, ceilings, or under sinks—often go unnoticed until mold becomes visible. And Lake Oswego’s humid environment after rainstorms creates the perfect breeding ground.
Watch for musty smells, warped wood, or visible mildew, which may indicate plumbing leaks hidden behind surfaces. Mold is not only expensive to remove but also a health hazard, especially for those with respiratory issues or allergies.
Action Step:
If you suspect a leak, a non-invasive leak detection can quickly locate the issue before it becomes a mold nightmare.
