Your water service line is the single pipe that carries fresh water from the city main (or your well) into your home — and when it leaks or fails, the signs are a soggy strip across the yard, dropping water pressure, a rising water bill, or discolored water. Cogan Plumbing repairs and replaces water lines across Central Arkansas, with trenchless options where the site allows. We’re a licensed, insured, family-owned company with flat upfront pricing, no overtime charges, and 24/7 emergency service. Call (501) 317-0637.
The water line is the lifeline of your plumbing
Every drop of water you use enters the house through one pipe: the water service line, running underground from the city water main at the street — or from your well in outlying areas — to your home. It’s out of sight, so it’s easy to forget about. But when it develops a leak or fails outright, it affects the whole house, and because it’s buried, the repair involves locating and accessing the line correctly.
Cogan Plumbing repairs and replaces water service lines for homeowners across Pulaski, Saline, Faulkner and Lonoke counties — Little Rock, North Little Rock, Sherwood, Maumelle, Jacksonville, Conway, Cabot, Benton, Bryant and surrounding towns. We diagnose the problem accurately, then recommend the repair that actually fits it.
Signs your water line is failing
- A wet, soggy or sunken strip in the yard, often running from the street toward the house — a buried line leaking up to the surface.
- Water pressure that has dropped throughout the home, sometimes gradually.
- A water bill that climbs with no change in usage — water escaping the line still gets metered.
- Discolored, rusty or gritty water — a sign of a corroding metal line or soil entering through a breach.
- The sound of running water with no fixtures on.
- An unusually green or fast-growing patch of grass over the line’s path.
- Air sputtering from faucets, which can indicate a compromised line drawing in air.
Why water lines fail in Central Arkansas
- Aging pipe materials. Older Little Rock homes — including Hillcrest and the Heights — may still have galvanized steel service lines that corrode shut and develop leaks from the inside, or polybutylene lines that crack and fail unexpectedly. Both are past their reliable service life.
- Clay soil movement. The expansive clay soil common across the region swells when wet and contracts when dry. That constant ground movement stresses buried pipe, cracks rigid lines and pulls joints apart over the years.
- Corrosion. Soil chemistry and hard water both work against metal pipe over decades.
- Tree roots. Roots from mature trees can crush, wrap or breach a water line as they grow.
- Freeze damage. A shallow or poorly protected line can crack during a hard Central Arkansas winter freeze.
- Age, simply. Every buried line has a service life. Decades in the ground eventually catch up with any material.
Repair or replace your water line?
When the damage is a single break in an otherwise sound line — say, a line that’s relatively modern and just cracked from soil movement — a targeted repair often makes sense. When the line is old galvanized steel or polybutylene, has leaked before, or is corroded along its length, replacement is usually the better value: repairing one weak spot on a failing pipe tends to be a down payment on the next repair. We’ll tell you honestly which situation you’re in after we’ve assessed the line.
Trenchless water line replacement
Replacing a water line once meant a trench dug across the entire yard. Today, where the site and the existing line allow, trenchless methods can replace a service line through small access points at each end — sparing your lawn, driveway, walkways and landscaping from a full excavation. It’s faster to restore the site and far less disruptive. Not every line qualifies; the path, the depth, the pipe condition and what’s above ground all factor in. We’ll tell you whether trenchless is an option for your home, or whether a conventional dig is the more reliable route.
City water and well water in our service area
Inside the cities — Little Rock, North Little Rock, Conway, Benton and the rest — the service line runs from the public main, and the homeowner is typically responsible for the line from the meter to the house. In outlying towns such as Greenbrier, Vilonia, Ward, Lonoke and Haskell, some homes run on well water, where the line carries water from the well and pump system instead. The repair principles are the same, but the layout differs, and well systems bring their own pump and pressure-tank considerations. Either way, we’ll work with what your property has.

Frequently asked questions about water line repair
How do I know if my water line is leaking?
Common signs are a soggy or sunken strip in the yard, water pressure dropping throughout the house, a water bill rising without more usage, discolored water, and the sound of running water when nothing is on. An unusually green or fast-growing patch of grass over the line’s path is another tell. If you notice these, have the line assessed.
Who is responsible for the water line, me or the city?
In most cases the city or utility maintains the main and the portion up to the meter, while the homeowner is responsible for the service line from the meter to the house. The exact dividing point can vary by municipality, so it’s worth confirming with your local utility. We can help you understand which section your problem falls in.
What is trenchless water line replacement?
Trenchless replacement installs a new service line through small access points at each end, rather than digging a trench across the whole yard. It spares your lawn, driveway and landscaping and is quicker to restore. Not every line qualifies — the path, depth and pipe condition all matter — so we assess the site before recommending it.
Should I repair or replace my water line?
If the line is otherwise sound and the damage is a single break, a targeted repair often makes sense. If the line is old galvanized steel or polybutylene, has leaked before, or is corroded along its length, replacement is usually the better long-term value, since repairing one weak spot on a failing pipe often just delays the next repair. We’ll give you an honest assessment.
How long does a water line replacement take?
It depends on the method, the length of the line, and the site. A trenchless replacement is often completed faster and with far less site restoration than a traditional excavation. Once we’ve assessed your line and you’ve chosen an approach, we’ll give you a realistic timeline and a flat price.
Why does my older Little Rock home keep having water line trouble?
Older neighborhoods such as Hillcrest and the Heights often still have galvanized steel or polybutylene service lines. Galvanized corrodes and clogs from the inside and develops leaks; polybutylene becomes brittle and can fail without warning. Combined with clay soil movement, these aging materials make repeat water-line trouble common in older homes.
Is a broken water line an emergency?
It can be. A major break can leave your home with little or no water and can flood the yard or undermine paving. If you’ve lost water or have water surfacing in the yard, shut off your main valve if you can and call our 24/7 emergency line. We’ll get the line diagnosed and your water restored.
