Hanahan homes, decade by decade
Hanahan was incorporated in 1973, and its population grew from 8,376 in 1970 to 13,224 in 1980. A lot of those households moved into houses built in the 1970s, which means many Hanahan homes now carry plumbing that has been in service for around half a century.
Permit and inspection rules vary by jurisdiction, and plumbing codes adopted locally can differ across the line between towns. Ask the correct building office for your address which standards and permits apply before a larger repair begins.
That age shows up in a few predictable places. Tank water heaters from that era have usually been replaced once or twice, shutoff valves under sinks may no longer close completely, and older supply lines can weep at fittings. When you call, tell us roughly when the house was built, and consider a water heater replacement before a tank fails on its own schedule at midnight.
Hidden leaks: the call that comes in most
The most common Hanahan problem is also the quietest. The water bill climbs, a meter keeps turning with every tap off, or a utility notice says there may be a leak. Nothing is visibly wet, so owners often wait, and the leak runs the whole time.
You can run the first test yourself. Turn off every fixture and appliance that uses water, then watch the meter for a few minutes. If the dial or low-flow indicator still moves, water is escaping somewhere, and leak detection can trace it with acoustic listening gear and tracer methods before anyone cuts into a wall or digs up a driveway.
Hanahan has been described as mostly a bedroom community for Charleston, which has a practical meaning. Many households are empty for eight or ten hours a day, so a small leak can run unnoticed until evening. A quick meter check when you get home, and shutting the main valve before a long trip, catches problems early.
Hanahan symptoms and the usual next step
| What you notice | What it often points to | Where it goes |
|---|---|---|
| Meter moves with all fixtures off | A leak between meter and house, or a running toilet | Leak detection |
| Warm patch or dampness on a concrete floor | A hot water line under the slab | Slab leak repair |
| Wet lawn strip between meter and house | A failing water service line | Water service line repair |
| Gurgling at several drains at once | A partial blockage in the main drain | Drain cleaning or sewer line cleaning |
| Sewer smell with a dry trap or cracked pipe | A damaged drain or sewer lateral | Sewer line repair |
A floor that feels warm underfoot or a damp patch near the foundation usually means a pressurized line under the concrete. That is the territory of slab leak repair, where the pipe is pinpointed first so the opening in the floor is as small as possible. A soggy strip of lawn between the meter and the house tells a similar story for the buried line, handled by water service line repair.
Drains, sewers and knowing which pipe is yours
The Highland Park Fire and Water District became a public service district in 1946, with sanitary and storm sewer powers. Districts and providers matter to you for one reason: they usually maintain the main in the street, and you maintain the lateral that runs from your house to it. Confirm your own water and sewer provider with your bill before you assume who owns a problem.
A simple rule helps. If the backup shows up inside your house in a tub, shower or floor drain, the blockage is often on your side and a plumber can clear it. Drain cleaning handles the sink, tub and branch lines.
When the line fills up again within weeks, hydro jetting cleans the pipe wall, and when a camera finds a crack or a sag, sewer line repair fixes that section. If wastewater is coming out of a manhole in the street, leave it alone and report it to your sewer provider.
The reservoir, the water plant and your own meter
Hanahan has a long relationship with public water. The Goose Creek Reservoir was built in the 1930s and was later developed into a 100-acre park, and the main water plant of the Charleston Public Works Commission, now Charleston Water System, is in town. A 23-mile pipeline from the Edisto River was built in 1936 to supply it.
It would be easy to read that history as proof that every Hanahan address has trouble-free water, but it says nothing about the pipes inside your walls. Your leak is on your side of the meter no matter how big the plant down the road is. Treat the plant as a reason to know your own shutoff valve, not as a sign that your lines are fine.
The city's name comes from J. Ross Hanahan, the first chairman of the Charleston public waterworks. The community was called Saxon until 1917, when the post office required a new name. If you are tracing an old property record that mentions Saxon, ask your title company, because the plumbing in the house is the same no matter what the paperwork says.
Before we arrive: burst pipe or active leak
- Shut off the main water valveTurn it clockwise until it stops. If it will not move, do not force it with tools, since a broken valve makes things worse. Tell the dispatcher so the plumber brings the right parts.
- Open a low faucetOpening one tap on the lowest floor drains the pressure still in the pipes and slows the flow from the break.
- Cut power near the waterSwitch off breakers for wet rooms only if the panel is dry and you can reach it without standing in water. If water touches outlets, stay out and call.
- Move belongings and take photosLift rugs, electronics and papers out of the wet area. Photograph the damage for your insurer before cleanup begins.
- Call the 24/7 lineDescribe where the water is and what you have shut off. Same-day appointments are offered when available, and nights and weekends are handled like any other hour.

☎ Call (855) 575-2890A twelve-square-mile city on the I-26 corridor
Hanahan covers about 12 square miles in lower Berkeley County, with access to I-26. For plumbing calls that means dispatch works by address, not by neighborhood name. Give the street and the nearest cross street, and say which side of any highway you are on, because the route to your door depends on it.
Businesses along the corridor use the same line. A clogged floor drain, a restroom backup or a failed water heater in a shop is a commercial plumbing call, and it helps to say whether the building has a grease trap, a flushometer toilet or a tank-style heater. Sewer problems in older buildings often need a camera sewer inspection before anyone proposes a repair.
Hanahan services, in the order we hear about them
Leak detection and slab leaks come first, followed by service line problems and clogged drains. Next come water heaters and the fixtures that fail at night: a toilet that will not stop running through toilet repair, a valve that will not shut through faucet repair, and a jammed unit under the sink through garbage disposal repair.
If a pipe has actually burst, burst pipe repair is the right page to read, and a house with repeated pinhole leaks may be a candidate for repiping. Planned work such as a new fixture or hookup can be scheduled for daytime hours. Goose Creek next door has the same menu, and the full services page lists everything.

The only ZIP code we have verified for Hanahan is 29410, and that is the one this page is built around. Neighboring ZIP areas are handled by the Goose Creek line on request, so call with your address and we will confirm coverage before sending anyone. We do not list ZIP codes we have not verified.
Yes. The line is open 24/7, including nights, weekends and holidays. Same-day appointments are offered when available, and the plumber explains the cause and gives a clear price before work begins. If gas is involved, leave the building and call the gas utility or 911 first.
Start with the meter test: turn everything off and see whether it still moves. Then listen for a running toilet, check outdoor spigots and look at any irrigation. If the meter keeps turning, the leak may be buried, and leak detection can trace it without random digging.
If sewage rises inside the house in a tub, shower or floor drain, the blockage is often on your lateral. If it shows up in the street at a manhole, call the sewer provider. Check your bill for the provider name and ask a plumber to run a camera if you are still unsure.
Not automatically. A tank that has been in service for a long time and shows rust at the seams, damp insulation or pooled water deserves replacement planning. A plumber can check the relief valve and fittings first, and tell you honestly whether repair or replacement makes sense.
Yes. Say it is a commercial building when you call and describe the problem, such as a floor drain, restroom or water heater. We send a licensed plumber who handles commercial work, and we recommend asking about after-hours access to the building.
Yes. The reservoir park sits inside Hanahan, so addresses nearby are handled like any other Hanahan call. Give the street and nearest cross street, and the dispatcher will confirm coverage for your exact location.
