Water Leak Detection & Repair in Tigard, Oregon
A hidden water leak can run for months before you see any visible damage — and by then, the mold, rot, and structural damage are already well underway. True Flow Plumbing locates and repairs leaks in Tigard homes using pressure testing and acoustic detection, without tearing your house apart to find it.
Leak Detection for Tigard Homes
Tigard's predominant construction era — the 1970s and 1980s — put a lot of copper water lines in the ground that are now 40–50 years old. Copper doesn't last forever, especially in areas with aggressive water chemistry. Pinhole leaks in copper pipes behind walls and under slabs are the most common leak calls we get in Tigard. Metzger and Summerfield also have older galvanized plumbing from the 1950s and 1960s that develops leaks at joints and fittings. We locate the source before we open anything.
🔍 Hidden Pipe Leaks
Supply line leaks inside walls, under floors, or in crawl spaces — found with pressure testing and acoustic equipment, not guesswork.
🏠 Slab Leaks
Pipes that fail beneath a concrete slab are one of the most damaging leaks in any home. We locate the exact spot before we touch the concrete.
📍 Pinhole Leaks
Pinhole leaks in copper and galvanized steel are common in 1970s and 1980s construction. They weep slowly — barely noticeable until the drywall is soaked or mold appears.
🚿 Fixture & Supply Line Leaks
Leaks at shutoff valves, supply lines under sinks and toilets, and fixture connections — diagnosed and repaired in one visit in most cases.
💧 Main Line Leaks
A leak in the service line between the street and your house can go undetected for months. Signs: wet yard, high water bills, low pressure everywhere.
🌡️ Thermal & Acoustic Detection
We use acoustic listening equipment and thermal imaging to find leaks without invasive opening of walls or floors before we know where the problem is.

Frequently Asked Questions
How do you find a hidden water leak in a Tigard home?
We start with a pressure test to confirm an active leak in the supply system, then use acoustic listening equipment to narrow down the location without opening walls or floors until we know exactly where to cut. This saves you from unnecessary demolition and repair costs.
What are the signs of a hidden pipe leak in Tigard?
A water bill that jumped without a change in usage, the sound of running water when everything is off, wet spots on walls or ceilings, a mold smell without visible water, and unexplained low pressure are the most common signs. Any one of these is worth a call.
Do you repair the leak the same day you find it?
In most cases yes — we come prepared to both locate and repair. Simple pipe repairs and fitting replacements are handled the same visit. More involved slab leak repairs may require a follow-up, but we'll tell you exactly what you're looking at before we schedule anything.
Does homeowner's insurance cover leak detection and repair in Tigard?
Most policies cover sudden and accidental pipe failures, including the cost of accessing the leak (opening walls, cutting into a slab). They typically don't cover gradual leaks that went unreported. Document everything and call your insurance company as soon as you discover a leak — we can provide a written report of our findings if needed.
