Why does my kitchen drain keep clogging after I use drain cleaner?

Liquid drain cleaner burns a narrow channel through the clog and leaves most of it behind. The grease coating on the pipe wall stays put, and it traps food scraps and soap again within a few weeks. Repeated doses are also hard on older cast iron drains. A cable machine reopens the line, but jetting cleans the full wall so the clog doesn't rebuild. If water backs up into the other side of a double sink, the blockage sits past the trap and needs professional clearing.

Who should I call for a trusted plumber in Mount Pleasant, SC, today?

Call Mr. Rooter Plumbing of Greater Charleston. Our team handles drain cleaning, HydroScrub® Jetting, and trenchless sewer repair for homes and businesses needing a plumber in Mount Pleasant, SC. Tell us what's happening, and we'll give you an upfront price before any work starts. We also take on repiping, leak repair, and water heater repair or installation, backed by the Done Right Promise®. Reach out online or by phone now, and we'll schedule a time that fits your day.

Do I need a permit for plumbing work in Mount Pleasant?

Most work beyond a simple repair needs one. Water heater replacements, repiping, sewer line replacement, and fixtures added in a new location generally require a Town of Mount Pleasant permit and a final inspection. South Carolina adopts the International Plumbing Code with state modifications, and the town inspects to the edition the state has adopted. We pull the permit and coordinate the inspection for you. Unpermitted work tends to surface later, during a home sale inspection, when fixing it costs more.

Does my irrigation system need backflow testing?

In most cases, yes. An irrigation line tied to your drinking water needs a backflow preventer, so fertilizer and lawn chemicals don't siphon back into the supply. Mount Pleasant Waterworks runs a cross-connection control program, and testable assemblies are generally checked once a year by a certified tester who reports results to the utility. Neighborhoods with large irrigated lawns, like Park West and Rivertowne, have plenty of these assemblies. A hard January freeze cracks their brass bodies more often than people expect, and our plumbers repair or replace damaged units.

How does the coastal climate affect my water heater?

Salt air and summer humidity rust the tank jacket, the gas burner assembly, and the flex connectors faster than they would inland. Inside the tank, the anode rod corrodes on purpose so the steel doesn't. Once the rod is spent, the tank starts to rust through. We check the anode rod every few years and replace it before it's gone, which adds life to the tank. Most manufacturers also call for flushing sediment once a year, and we test the temperature and pressure relief valve on the same visit.

Should I test my water for lead?

Homes plumbed before 1986 carry the most risk, because federal Safe Drinking Water Act amendments that year banned lead pipe and lead solder in new plumbing. Start with the annual water quality report from Mount Pleasant Waterworks, which covers the utility's side of the system. Lead usually enters at the house, from old solder or brass fittings, so the report won't show it. A test from a state-certified lab using water from your own tap gives a real answer. Until then, run cold water for a minute or two after the pipes sit overnight, and use only cold water for drinking, cooking, and baby formula.

What areas outside Mount Pleasant does your team serve?

North of the Cooper, our crews cover Daniel Island and Hanahan for drain, leak, and water heater calls. Restaurants and older homes with grease-heavy lines count on our hydro jetting in North Charleston, SC, to clear buildup a cable machine leaves behind. The same upfront pricing and guarantee apply on every call, wherever you live. Across the rivers, we also serve James Island , West Ashley , and Summerville . Those homes see many of the same problems, from root intrusion in older clay lines to water heaters worn down by humidity. Call the same number, and the closest available crew gets dispatched.

Why do I smell sewer gas or hear gurgling after I flush?

Start with the simple check. An unused guest shower or floor drain dries out, and a dry trap lets sewer gas into the room, so pour a bucket of water into it first. Gurgling at several fixtures is a different story, because it usually means the main line isn't draining freely. Roots from live oaks and wax myrtles chase moisture, and a hairline crack in a clay or cast iron joint is enough to let them in. A camera inspection shows where the roots are and how far the damage runs. For homes in low-lying spots, we also install backwater valves that stop sewage from flowing back into the house when the municipal line surcharges during heavy rain.

How do I know if my home has polybutylene or galvanized pipe?

Check where the water line enters the house, near the water heater, and under sinks. Polybutylene is flexible plastic, usually gray, often stamped PB2110, with copper or aluminum crimp rings at the fittings. Galvanized steel is dull gray metal with threaded joints, and a magnet will stick to it. Rust-tinted water on the first draw, pinhole leaks, and falling pressure all point toward a repipe. Our plumbers inspect exposed runs and test pressure at several fixtures before recommending a full or partial repipe.

Why is my water pressure low, or why do my pipes bang when a faucet shuts off?

Low pressure at one fixture usually points to a clogged aerator or a worn cartridge. Weak pressure through the whole house points to a failing pressure-reducing valve, a partly closed main valve, or corroded galvanized pipe. High pressure causes its own damage, and banging pipes are often the first sign. The International Plumbing Code requires a pressure-reducing valve when static pressure passes 80 psi, since pressure above that wears out toilet fill valves, water heater relief valves, and washing machine hoses. We test static pressure at a hose bib with a gauge and replace the regulator if it's out of range.

Plumbing Services for Mount Pleasant Homes and Businesses

Drain Cleaning and Unclogging

A cable machine clears a hair clog in a bathroom sink in a few minutes. Kitchen lines are a different problem, because grease coats the pipe wall and catches everything that follows it. We clear those with HydroScrub® Jetting, which sends high-pressure water through the line to strip grease, scale, and sand back to bare pipe. Our crews bring the same hydro-scrubbing equipment to North Charleston, SC, where older restaurant and warehouse lines see heavy grease loads.

Trenchless Sewer Repair

Many Old Village homes still drain through cast iron or clay sewer lines laid generations ago. Roots find the joints, and cast iron rusts from the inside until the bottom of the pipe gives way. Pipe relining sets a resin-coated liner inside the old line and cures it in place, so your driveway and yard stay intact. For a collapsed section, pipe bursting pulls new HDPE pipe through the path of the old one from two small access pits. We will be happy to walk you through your trenchless repair.

Repiping

Homes built between 1978 and 1995 often used polybutylene, a gray plastic supply pipe that breaks down from the chlorine in treated water. Snee Farm and other neighborhoods from that era still have plenty of it behind the drywall. We replace polybutylene and corroded galvanized lines with PEX or copper. Our plumbers plan the route of the new lines to keep wall openings to a minimum during your home’s repiping.

Water Heater Repair and Installation

We repair and replace tank and tankless units, from a failed heating element or thermocouple to a full swap. On a replacement, we size the water heater unit to your household, check the venting, and add a thermal expansion tank where a closed system calls for one. Tankless units need regular descaling, and we handle that service too.

Leak Repair and Faucet Work

A water meter that keeps spinning with every fixture off tells us water is escaping somewhere. We track slab and in-wall leaks with acoustic listening equipment before we open anything. Faucet repair and installation covers cartridge replacement, new supply lines, and full kitchen or bath fixture upgrades.

Why Mount Pleasant Homeowners Call Mr. Rooter Plumbing

Mr. Rooter Plumbing of Greater Charleston opened in 2002, years before the first homes went up in Carolina Park. Since then, our team has worked on 1920s cottages in the Old Village and newer builds in Dunes West. That history tells us which pipe we'll likely find behind a wall before we open it. It also means we know how local soil, tides, and trees affect a sewer line over 30 or 40 years.

Every job starts with a written, upfront price. You approve it before work begins, and the number doesn't change if the repair runs long. We never add overtime charges for nights, weekends, or holidays. Emergency calls get answered 24/7, and that includes a burst pipe at 2 a.m. on a Sunday.

Each plumber on our team passes a background check and arrives in uniform at the time you booked. Our crews protect the work area and clean up before they leave. Our work is backed by the Done Right Promise®, along with a parts-and-workmanship guarantee. If something isn't right, we come back and fix it at no extra cost.

Business owners get the same crews and the same pricing rules. Commercial kitchens around Shem Creek and offices along Coleman Blvd call us for grease line jetting, restroom fixture repair, and commercial water heater service. We schedule that work around your hours so your doors stay open. When you want a plumber in Mount Pleasant, SC, who shows up with a plan and a price, that's the visit we deliver.
