Plumbing in South Carolina corrodes on the coast and clogs or hides inland. Salt air eats water-heater jackets, supply valves, and outdoor bibs on island and peninsula houses. Older towns still have galvanized lines and cast-iron drains that scale and split. Midlands slabs leak under a warm spot on the floor or announce themselves with a meter that spins while every tap is closed. The Upstate adds a freeze risk to crawl-space lines that the Lowcountry barely considers. Wells and septic tanks cover a lot of rural lots. Say if that is you.
Stop the water if you can. Know whether the main turns, because a painted-shut valve is a discovery you do not want during a burst. Say supply or drain. A dripping lavatory valve is not an attic heater that just emptied through a ceiling. A slow tub is not automatically a broken sewer. Gurgling across several fixtures when a washer dumps may be the building drain or a dry vent. That difference belongs in the first minute.
A cable clears a blockage and leaves a crushed or root-filled pipe where it was. Ask which outcome you are scheduling, and ask whether a camera comes out if the stoppage returns. Coastal high water can complicate a yard line that inland clay does not. Water-heater replacement should name fuel, tank or tankless, a pan, a shutoff, discharge piping, and haul-away. Near salt air, the pan and the condition of the flue or the electrical whip matter because corrosion gets there first. Small fixture jobs should be called small.
Thaw a frozen Upstate line without an open flame in a crawl space. After a tropical rain, a floor drain that burps storm water is a symptom to describe, not a reason to pretend the ocean is a plumbing part. Outdoor showers on coastal houses leak at the valve and rot the siding behind them. Say so if that wall is soft. Rural septic calls are not city-sewer calls. The truck and the diagnosis both change.
Tell them leak, drain, or heater, and whether you have already stopped the flow. Plumbing in South Carolina starts with shutoff, salt or clay, and a clear symptom. Call the number on this page.
