Water Heater Installation & Replacement
Tank and tankless replacement, sized to your household and your gas or electric supply.
Burst pipe at midnight, sewage in the tub, no hot water on a Sunday. Call at any hour, describe what is happening, and hear the price before any work begins.

Shut off the main valve, then call. Every hour, every day.
An emergency plumber is the person you call when a pipe, drain or water heater fails and waiting until Monday would cost you a floor, a ceiling or a night without water. In Columbia, SC that call can come from a 1950s brick ranch in Forest Acres, a rental near Five Points or a newer house off Lake Murray, and the failure is rarely the same twice.
Columbia 24/7 Plumbing takes calls every hour of every day, including weekends and holidays, for homes and businesses in Columbia, Forest Acres, Cayce, West Columbia, Irmo, Lexington, Blythewood, Chapin and Hopkins. Call (844) 981-1691, say what you are seeing, and get a clear price before anyone starts work.
Some problems can wait for a weekday appointment. These cannot. A burst pipe can put hundreds of gallons into a house in an hour, so shutting off the main and calling a 24/7 emergency plumber comes first. Sewage coming up through a floor drain or tub means the main line is blocked, and drain cleaning or a camera look at the sewer line cannot wait.
A water heater that is leaking from the tank, not from a fitting, is usually finished, and a same-day water heater replacement is often the faster fix than repeated water heater repair visits. A sump pump that has stopped during heavy rain, a gas smell near an appliance, or water running under a slab with no visible source all deserve a call right away.
If you smell gas, leave the house and call 911 and the gas utility first. Then call us for the plumbing side.
Emergency calls are the front door, but most Columbia homeowners also need planned work. The most requested jobs in the area are below, and each has its own page with local detail and what affects the price.
Tank and tankless replacement, sized to your household and your gas or electric supply.
No hot water, lukewarm water, leaks at the fittings and strange noises.
Kitchen, bath and main line clogs cleared, with a camera look when it keeps coming back.
Flushing, error codes and replacement for on-demand units.
Drainage, sump systems and moisture control for below-grade spaces.
Root intrusion, cracked clay and failed joints found on camera and fixed.
The full list also covers leak detection, slab leaks, toilet repair, garbage disposals, gas lines, water softeners and commercial plumbing. See every service on the all services page. If water damage has already spread past the pipe, we also take calls for water damage restoration.
Permanent repairs follow the South Carolina Plumbing Code, which is the International Plumbing Code (IPC) with state modifications. Larger jobs such as a water heater replacement, a rerouted drain or a new gas line may also need a permit from the city or county building department, and the work should be inspected where the local rules require it.
Columbia Water draws from two sources, the Broad River Diversion Canal and Lake Murray, and treats the water at two plants. The utility describes its water as 1 to 2 grains per gallon, which is on the soft side. That matters because many online guides blame hard water scale for every Columbia plumbing problem. With city water, scale is rarely the main culprit. Age and material usually are.
Chloramine is the other local factor. Columbia Water has used it as a disinfectant since the mid-1960s at the Canal plant and since 1982 at the Lake Murray plant. Chloramine is harder on some rubber parts than chlorine alone, so a toilet flapper, supply hose or water heater gasket that fails early is worth replacing with chloramine-resistant parts instead of the cheapest ones on the shelf.
Use the table below as a quick guide to what is probably behind a leak or a slow drain in your house. It is a starting point, not a diagnosis, and a technician confirms the real cause on site.
| Home built | Common pipe materials | What usually fails first |
|---|---|---|
| Before 1960 | Galvanized steel supply, cast iron or clay drains | Rusted supply lines, root-clogged clay sewer |
| 1960s to 1970s | Galvanized or early copper supply, cast iron drains | Low pressure, pinhole leaks, slow main drain |
| 1978 to 1995 | Copper, with gray polybutylene in some builds | Fitting failures at joints and connectors |
| After 1995 | Copper, CPVC or PEX supply, PVC drains | Water heater age, fixture seals, supply hoses |
Forest Acres is a good example of the first two rows. The city incorporated in 1935 and had water lines in place by 1939, and much of its housing is mid-century brick.
Homes like that often still have original galvanized supply pipe, which commonly runs out of life after 40 to 50 years. If you are seeing brown water or weak pressure, ask about repiping before you pay for several separate repairs. For hidden wet spots, leak detection finds the source without opening walls first.
In early October 2015, record rain hit the Columbia area. One gauge on Gills Creek in Forest Acres logged 10.64 inches in four hours, dams in the Gills Creek watershed failed, and the Columbia Canal breached, which led to a citywide boil-water advisory. Saturated ground pushes water into sump pits and sewer lines, and homes in low-lying spots feel it first.
The practical takeaway is cheap compared with the damage. If your home sits near Gills Creek, Rocky Branch or the Congaree floodplain, have a sump pump tested before storm season and ask whether a backwater valve belongs on your sewer line. Annual backflow testing matters too if you irrigate or run a commercial property.
Homeowners policies often cover sudden events like a burst supply line and often exclude slow leaks that went unnoticed for months. Your policy language decides, so keep the photos and ask your insurer before you assume either way.
Dial (844) 981-1691 any hour. Describe the problem and tell us where your shutoff valve is.
You hear the price before work starts. Non-emergency estimates are free.
The first job is containing the water, the backup or the leak.
If a permanent repair needs parts or a second visit, you get a plan, not a surprise.
We answer plumbing emergencies across Richland and Lexington counties. In the city of Columbia that includes ZIP codes 29203, 29210, 29223 and 29229. Forest Acres in 29206 and 29204 is mostly mid-century housing, so galvanized supply lines and cast iron drains are the usual suspects there. Irmo and the Lake Murray shoreline in 29063 and 29212 straddle the Richland and Lexington county line, which affects who handles permits and utilities from one street to the next.
Across the Congaree we cover Cayce in 29033 and 29172 and West Columbia in 29169 and 29170. Farther west, Lexington in 29072 and 29073 is a short drive for most calls. Each town has its own page covering its housing age, ground conditions and the plumbing problems that fit them.
North and east of the city we cover Blythewood in 29016 and 29229 and Northeast Columbia in 29223 and 29203. Out toward Lake Murray, Chapin in 29036 and 29075 is on the same route, and Hopkins in 29061, 29209, 29052 and 29044 anchors the Lower Richland side.
Inside the city, plumbing changes with the neighborhood. Shandon grew from the 1890s along an electric streetcar line and is full of Craftsman bungalows and American Foursquares. Earlewood dates to 1910 and Elmwood Park to a 1905 land auction, so both hold early 1900s pipe.
The Congaree Vista is a former warehouse district between downtown and the river that is now restaurants, shops and hotels, and Five Points, the city's first neighborhood shopping district, serves Shandon and the University of South Carolina side of town.
Landmarks help dispatch find you quickly. Tell us if you are near Williams-Brice Stadium at George Rogers Boulevard and Bluff Road, Riverbanks Zoo on the Saluda River or Fort Jackson, and we build the route from there.
Yes. Call (844) 981-1691 at any hour, including nights, weekends and holidays. Say if water is actively flowing so the first step is stopping it.
The price depends on the problem, the parts, how hard the pipe is to reach and the time of day. You hear the price before work starts, so there is no surprise at the end of the visit.
For non-emergency work, yes. In an emergency you get the price up front, and you decide whether to go ahead.
Columbia Water reports about 1 to 2 grains per gallon, which is soft. Heavy scale is unusual on city water. If you are on a private well outside the city system, hardness can be very different and is worth testing.
Shut off the main water valve, keep clear of standing water near electrics, switch off the water heater if it is leaking, and take photos for insurance. If you smell gas, leave and call 911 first.
Yes. We take calls in Forest Acres, Cayce, West Columbia, Irmo, Lexington, Blythewood, Northeast Columbia, Chapin and Hopkins, and nearby ZIP codes in Richland and Lexington counties.
A 24/7 emergency plumber is one call away. Tell us what is happening and hear the price first.
