Not all plumbing leaks announce themselves with dramatic flooding. Often, the most damaging water leaks are slow, silent pinholes concealed inside wall cavities, ceiling floor joists, or under crawlspaces. Over weeks and months, continuous moisture rots framing studs, fosters toxic black mold, and compromises the structural integrity of your Portland home.
United Plumbing PDX utilizes advanced non-destructive electronic leak detection equipment to locate hidden leaks quickly without turning your living room into a demolition zone. Once found, our licensed plumbers repair the damaged piping cleanly, restoring your peace of mind and stopping water waste.

Signs of a Hidden Plumbing Leak in Your Home
Check your water meter: Make sure no water is running inside or outside. Look at your water meter register—if the small red or blue flow indicator triangle is spinning, water is escaping somewhere in your system.
Inspect wall baseboards: Look for peeling paint, bubbling wallpaper, or baseboards that have pulled away from drywall. These are classic indicators of moisture wicking through wall studs.
Pinhole Leaks in Vintage Portland Copper Plumbing
Homes built in the 1960s through 1980s often feature thin-walled Type M copper piping. Due to chloramine water treatment and natural flow turbulence, internal pitting corrosion produces microscopic pinhole leaks that spray fine, pressurized mist inside walls for months before staining surfaces.
Transparent Pricing & Cost Factors
Pricing depends on whether the leak is exposed under a sink or concealed behind bathroom tile, deep in crawlspaces, or underneath concrete.
- Concealment level (exposed under vanity vs. behind tiled shower or in unconditioned crawlspace)
- Equipment required (FLIR thermal imaging, acoustic listening, pipe locator sondes)
- Pipe composition (vintage copper pinhole leak vs. PEX fitting vs. cracked cast-iron drain)
- Accessibility and restoration requirements

Frequently Asked Questions
How do you find a leak behind a wall without cutting drywall?
We use infrared thermal imaging cameras that detect microscopic temperature differentials caused by escaping moisture, alongside acoustic microphones that amplify the high-frequency hissing of pressurized water escaping tiny fissures.
Can a slow leak cause black mold in Portland?
Yes. In our humid Pacific Northwest climate, mold spores germinate on wet drywall and wood framing within 24 to 48 hours of moisture exposure, making rapid leak repair essential.
Will the city credit my water bill if I had a hidden leak?
Yes. The Portland Water Bureau has an underground/hidden leak adjustment policy. After we complete the repair, we provide a formal repair invoice stating the leak was fixed, which you can submit for a partial utility credit.
What is the difference between a supply line leak and a drain leak?
A supply line leak is under constant pressure (50 to 80 PSI), so it leaks continuously whether fixtures are in use or not, turning the water meter dial. A drain pipe leak only releases wastewater intermittently when a sink, tub, or toilet above it is actively draining.
How do you test if a leak is coming from an upstairs bathroom shower pan?
We perform an isolated shower pan flood test by temporarily plugging the shower drain throat and filling the pan with 2 inches of water for 30 to 45 minutes. If water drips into the ceiling below, the pan membrane or drain flange seal has failed.
