Short answer: If you have a soggy patch of yard, unusually green grass or a high bill with no leaks inside, the problem may be an underground water line. Leak Seekers traces buried lines and pinpoints the leak so only a small area needs to be dug.
Underground lines we check
- The main water service line from the meter to the building
- Irrigation and sprinkler supply lines
- Pool and spa plumbing between the equipment and the pool
- Lines to outbuildings, guest houses and outdoor kitchens
- Commercial service and site lines
Signs of an underground leak
- Wet, soggy or sinking areas in the yard
- A patch of grass that's greener than the rest
- Water pooling near the meter box
- Low water pressure in the house
- A high bill with no visible leaks indoors
How we locate it
Depending on the situation, that can include acoustic listening equipment that hears water escaping a pressurized line, thermal imaging that shows temperature changes caused by moisture, moisture meters, line tracing to map where pipes run, and pressure testing to isolate which line is losing water.
We mark the leak location on the ground so your plumber or irrigation contractor can dig in the right place the first time.
