How do I know if I have an underground water line leak?

An unexplained spike in your water bill - without any change in usage - is the most reliable indicator. Other signs include one area of the yard that stays wet or produces unusually lush grass, a drop in household water pressure, or the meter dial spinning slowly with all fixtures off. Low-grade leaks can go unnoticed for months.

What causes underground water line leaks?

In Collin County, the two main causes are corrosion in aging galvanized steel lines (common in homes built before 1980) and soil movement. North Texas clay soil shrinks in drought and expands with rain, which stresses fittings and joints over years. Tree root intrusion near the water service line is also common in established neighborhoods.

Do you have to dig up my yard to fix a water line leak?

We do need to reach the pipe to repair it, but once the leak is located we open a small, targeted access point - usually a 2-4 foot dig or short tunnel rather than a trench across the yard. For older galvanized lines with corrosion throughout, we often recommend replacing the run at the same time to avoid a second dig later.

Water Line Leak Repair in Collin County

Your main water line runs from the meter at the street to the point where it enters your home. A break anywhere along that run loses water underground - you won’t see a puddle inside, but you will see it on your water bill.

The Meter Test

Turn off every fixture in your home. Go to the water meter and watch the indicator dial or sweep hand. If it’s moving, water is flowing somewhere it shouldn’t be. This is the first step we walk every customer through over the phone before dispatching.

Reaching the Leak

Once the leak has been located, we open a small, targeted access point - usually a 2-4 foot dig or a short tunnel - instead of trenching across the yard. Precise access means less soil disturbance, a faster repair, and a yard that recovers quickly.

After the Repair

We pressure test the line before backfilling to confirm the repair holds. For older galvanized service lines, we provide a written assessment of remaining pipe condition so you can plan ahead.
