What causes pinhole leaks in copper pipes?

Acidic water, high mineral content, or improper grounding that allows electrical current to pass through the pipes can corrode copper from the inside, creating tiny holes that spray water under pressure.

How do you locate a leak that's not visible?

Pressure testing isolates the leak to a specific zone, then tools like acoustic sensors detect the sound of water escaping under pressure, even through walls or concrete—thermal imaging also reveals temperature differences where water is saturating materials.

When does a gas line leak require evacuation?

If you smell gas strongly indoors, leave immediately without using light switches or electronics, then call the gas company and a plumber from outside the building—gas concentrations can ignite from sparks created by everyday electrical devices.

What's involved in repairing a burst pipe?

The damaged section is cut out, and a new piece is fitted and joined using soldering for copper, threading for galvanized steel, or compression fittings for flexible lines—once the repair is complete, the line is pressure-tested to confirm it holds without leaking.

Why does low water pressure sometimes indicate a hidden leak?

If only one fixture has low pressure, the issue is usually a clogged aerator or valve, but if the entire house experiences reduced pressure and the meter shows continuous usage, water is escaping through a leak before it reaches the fixtures.

Pipe/Gas Line Leaks

Water stains spreading across ceilings, the smell of gas near appliances, or water pressure that drops without explanation usually point to a leak somewhere in your plumbing or gas lines. My Cousin Vinnie provides leak detection, water pipe repairs, gas line repairs, and burst or damaged pipe repairs for residential and commercial properties in Wilmington, using pressure testing and visual inspection to locate leaks hidden behind walls, under floors, or underground. Pipes corrode from the inside as minerals and oxygen react with metal, and older homes often have galvanized steel or copper lines that develop pinhole leaks after decades of use.

The work includes water line repairs and replacements, gas line leak detection and repairs, corroded or deteriorating pipe solutions, low water pressure troubleshooting, and hidden plumbing leak troubleshooting. If a water meter continues running when all fixtures are off, water is escaping somewhere in the system—even a small leak wastes hundreds of gallons over weeks and saturates framing or insulation where it goes unnoticed.

Arrange an inspection if you notice unexplained increases in water bills, damp spots on walls or floors, or the smell of rotten eggs near gas appliances..

Leak detection begins with isolating sections of the plumbing system to determine whether the leak is in a supply line, a drain line, or a gas line, then narrowing down the location using pressure gauges, listening devices, or thermal imaging. Water leaks in pressurized supply lines spray steadily and cause visible damage quickly, while drain leaks only occur when water flows and may go unnoticed until mold or rot appears. Gas leaks require immediate attention because even small concentrations create explosion risks—natural gas is odorless, so utility companies add mercaptan to give it a sulfur-like smell that alerts occupants.

Once leaks are repaired, water pressure stabilizes across all fixtures, ceilings and walls dry out without new staining, and gas odors disappear completely because connections are sealed properly and tested for integrity. You'll also see lower water bills if a slow leak was running continuously, and indoor humidity levels drop if moisture was evaporating from hidden leaks into living spaces.

Emergency service is available for urgent leaks, and the work covers both finding the leak and making the repair, but does not include restoring drywall, flooring, or finishes damaged by water. If a gas line leak requires rerouting because the existing pipe is too corroded to patch, that's addressed during the same service call to restore safe operation..
