Main Water Line Leak Detection in Grand Forks
The service line between your meter and house can leak underground for months, especially in older galvanized or copper lines. Wet spots in the yard, unusually green grass or a sinking area near the front of the house are clues. We use line tracers to map the pipe and ground microphones to hear the leak. That keeps excavation to a small, focused hole.

Hidden Wall and Ceiling Leak Detection in Grand Forks
Leaks inside walls and ceilings often show up as stains, bubbling paint, soft drywall or a musty smell. We use thermal cameras to spot temperature differences caused by water, then confirm with moisture meters. Acoustic tools help when the leak is on a pressurized line. Pinpointing the source lets us cut a small, neat access opening.
Pool and Spa Leak Detection in Grand Forks
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak safeguards the pool shell and the soil around it.
Slab Leak Detection in Grand Forks
Slab leaks are a common concern for homes with concrete foundations, especially where soils shift. Our technicians use dedicated acoustic equipment and thermal cameras to pinpoint leaks under your home's foundation without destructive digging. Early detection of a slab leak prevents serious structural damage and mold issues, saving you significant repair costs down the line. We can locate leaks in both hot and cold water lines under the slab.

HPN Plumbing invests in modern leak detection technology to provide accurate and efficient service.
