Water Line Repair & Replacement in Columbia, SC
Between the meter box and the foundation runs a buried pipe that carries every gallon you use. Soggy turf, a spinning dial and weak pressure all point to it.
- Meter to house
- Trench or trenchless
- Locate before digging
Signs the leak is in the service line
A service line leak behaves differently from one inside the house.
- A wet patch or sunken spot in the yard. Water finds the easiest path up, which is often near the line.
- Pressure that fades across the whole house. A large leak before the house steals pressure from every tap.
- A meter that runs after you close the main. That places the leak between the meter and the house.
- Muddy or discolored water. A break lets soil enter the pipe when pressure drops.
Pipe materials and what they mean
The material of your existing line shapes the repair.
| Material | Where it is common | Repair note |
|---|---|---|
| Galvanized steel | Older homes | Corrodes from inside, replacement is usually better than patching |
| Copper | Mid-century to newer | Repairable, check for pinholes along the run |
| Polyethylene or PEX | Newer lines | Flexible, repair with approved fittings |
| PVC | Some service lines | Rigid, repair by section |
Soggy yard and no visible leak?
Call with your meter reading and a description of the wet area.
Repair, replace or trenchless
A single break in sound pipe is a spot repair. A line that has failed more than once, or is made of corroded galvanized steel, is better replaced. Trenchless methods pull a new line through the old path with only two small pits, which suits driveways and mature landscaping.
Call 811 before any digging. The free locate marks gas, electric and water lines. In South Carolina, the one-call center is the first step on any excavation.
Who owns which part of the line
The utility generally owns the main and the connection to the meter. The homeowner generally owns the line from the meter to the house. Policies vary by utility, so confirm yours.
Cayce and West Columbia run their own water systems, and the Town of Lexington buys water from the City of West Columbia. The utility that supplies your tap is the one to call about the street side.
Pressure and the water heater
A service line problem can show up at the water heater first. Pressure spikes can trip the relief valve, and low pressure can starve a tankless unit. If your heater misbehaves along with the faucets, read our page on water heater repair after the line is checked.
Reading your meter and checking your pressure
Most meters have a flow indicator that spins when any water moves. Find it before you need it, and note the reading at night and again in the morning. If the number changes while no one used water, you have a leak.
A pressure regulator near the main keeps house pressure in a safe range. Water pressure above 80 pounds per square inch is above what the International Plumbing Code (IPC) allows at fixtures, and below about 40 feels weak. A cheap gauge on an outdoor spigot gives you a number.
The meter is the line between you and the utility
Columbia Water owns the main and the meter, and the pipe to your house is yours. If the leak is near the street, call (803) 545-3300 first. In Cayce and West Columbia, the city utility plays that role, and some Lexington County homes use private wells with no utility meter at all. The Broad River Diversion Canal and Lake Murray feed Columbia Water, so street-side water problems go to its customer care line.
Long service lines in Hopkins, Chapin and Blythewood
Acreage lots in Hopkins and Blythewood and the sloped lots around Chapin mean a long run between the meter and the house. A leak on that run shows up as a soft patch, a high bill or low pressure long before water surfaces.
In Chapin, the town owns water lines only in part of town and the City of Columbia operates the rest, so who fixes the street side depends on the address.
What changes the price of a water line repair
Service line work is priced by length, depth and surface.
Some insurers and utilities offer optional service line coverage. Ask yours before paying for a large repair.
Want your real number? Call (844) 981-1691 and mention length and depth and surface above the line.
If the water line problem is bigger
To confirm the leak first, use the meter test on our leak detection page. If the whole house is old, a new service line may pair with repiping.
Water line questions
The meter is usually in a ground box near the street. The main shutoff may be at the meter or where the line enters the house.
Generally the line from the meter to the house is yours. The utility handles the main and the meter connection.
Many take a day or two, depending on length, depth and method.
A growing leak or a failing pressure regulator can cause intermittent drops. Check the meter and the regulator.
