Think Your Water Line Is Leaking?

A few quick checks tell you whether the leak is likely in the main line.

1. Check the Meter

Turn off every faucet and appliance and watch the meter's leak indicator. If it keeps moving, water is escaping somewhere.

2. Close the House Valve

Close the main shut-off inside the house. If the meter still moves, the leak is likely between the meter or curb and the house.

3. Call (610) 489-2717

Tell us what you found. We locate the leak, explain the repair and schedule it as soon as possible.

Water Line Leak Repair

The water service line is the pipe that carries water from the curb stop or meter into your home. Age, ground movement, frost, corrosion and tree roots can crack it, and a leak underground can run for weeks before you see it.

We locate the leak first so the excavation is as small as possible, then repair the damaged section and test the line before backfilling.

Low Water Pressure

Pressure drops throughout the house.

Wet or Sinking Yard

Soggy ground between the street and the house.

High Water Bill

Usage jumps with no change in habits.

Discolored Water

Rust or dirt from a damaged or aging line.

A wet spot in the yard that never dries, or grass that stays greener along a straight line toward the street, often marks a leaking water line.

Main Water Line Replacement

Older homes often still have galvanized steel or old copper service lines, and some have polybutylene. When a line has leaked more than once or is badly corroded, replacing it is usually the better value than repeated repairs.

We replace the line from the curb or meter to the house, connect it to a new main shut-off valve where needed, and restore the yard as closely as possible to how we found it.

Old Galvanized Lines

Corroded steel that restricts flow and leaks.

Repeat Leaks

Lines that have failed more than once.

New Shut-Off Valve

Reliable quarter-turn main valve inside.

Permits and Utilities

Utility mark-out and required permits handled.

If you are replacing an old service line, it is a good time to replace an old, hard-to-turn main shut-off valve with a quarter-turn ball valve.

Signs of a Main Water Line Problem

A leak in the main water line wastes water around the clock and can soften the ground around your foundation. The sooner it is found, the smaller the repair.

Call us if you notice any of these.

Water Line FAQs

In most areas the water company owns the main under the street and the homeowner is responsible for the service line from the curb stop or meter to the house. Your water supplier can confirm where your responsibility starts.

We start with meter and pressure tests to confirm the leak, then narrow down its location before digging, so the excavation is as small as possible.

A single leak in a newer line can usually be repaired. If the line is old galvanized steel or has leaked more than once, replacement is often the better long-term value. We explain both options first.

Most water line work needs some excavation. We keep it as small as possible and restore the area afterward.

A large leak can flood a yard or basement and should be handled right away. Close the main shut-off valve and call (610) 489-2717 any time.
