Located on US-321 in York—along the York-Clover corridor—Doan Sun Plumbing LLC is the 5-star professional partner that York County homeowners trust for flawless plumbing and sewer line health. Whether you are dealing with a backup in Clover, a slow drain in Sharon, or need a new mainline in McConnells, we provide the precision service necessary to keep your home’s waste systems flowing. We specialize in the critical plumbing infrastructure that fuels your septic system—ensuring waste leaves your house cleanly and reaches your tank without the line obstructions, breaks, or root intrusion that cause both indoor disasters and outdoor septic failures.
York County’s predominantly septic-fed households face a unique plumbing reality: indoor plumbing problems don’t just create inconvenience—they threaten entire septic systems. A broken sewer line leaking into your yard, tree roots invading the main line and creating backups, or chronic slow drains forcing septic tanks to work harder all accelerate system failures that cost $15,000-$30,000 to repair. Doan Sun Plumbing LLC understands this critical connection between indoor plumbing and outdoor septic health. We provide the professional sewer line repair, drain cleaning, and diagnostic services that prevent indoor plumbing disasters from becoming outdoor septic nightmares—protecting both your home’s functionality and your property’s most expensive infrastructure investment.
The Link Between Your Pipes and Your Septic Tank
A septic system is only as good as the pipes leading to it. The mainline sewer pipe running from your house to your septic tank is the “main artery” of your home’s waste system—when this line breaks, develops root intrusion, or becomes chronically clogged, it doesn’t matter how well-maintained your septic tank is. Waste can’t reach the tank properly, creating backups into your home, leaks into your yard, and hydraulic stress on your septic system that accelerates drainfield failure. We ensure your indoor plumbing and outdoor septic system work in harmony through professional sewer line maintenance and repair that keeps waste flowing where it should—not backing up into your home or leaking into your property.
- Professional Sewer Line Repair & Replacement — The mainline sewer pipe connecting your house to your septic tank faces persistent threats: tree roots seeking water that crack pipes and create blockages, clay soil movement that stresses and breaks rigid pipe materials, aging cast iron or clay pipes that deteriorate over decades, and settling that creates low spots where waste accumulates. When sewer lines fail, we provide both traditional excavation repair and trenchless solutions depending on damage severity and site conditions. Traditional repair involves excavating the damaged section, replacing broken pipe, and properly backfilling with compacted material. Trenchless repair uses pipe bursting or slip-lining techniques that minimize excavation—pulling new pipe through the old line or lining it with epoxy materials. We diagnose which approach suits your specific situation, providing honest recommendations based on cost-effectiveness and long-term reliability rather than upselling expensive solutions for problems requiring simple repairs.
- High-Power Drain Cleaning & Clog Removal — Slow drains throughout your house indicate developing clogs in main lines—problems that stress septic systems by forcing tanks to process water more slowly than designed. We provide professional drain cleaning using high-power equipment that removes clogs completely—not just poke holes through them like amateur attempts. Our cleaning services handle kitchen drains accumulating grease, bathroom drains blocked by hair and soap buildup, main line clogs from flushed debris, and partial obstructions reducing flow capacity. Professional drain cleaning prevents the recurring backups that homeowners attempt to solve with chemical drain cleaners—caustic products that damage pipes, harm septic bacteria, and provide only temporary relief before clogs return.
- Septic Line Clearing & Root Removal — The pipe section between your house and septic tank attracts tree roots seeking water—roots that invade through tiny cracks, grow inside the pipe, and eventually create complete blockages. When roots invade septic lines, simple drain cleaning won’t solve the problem permanently. We use specialized cutting equipment that removes roots from pipe interiors, restoring full flow capacity. For severe root intrusion, we provide pipe replacement or root barrier installation that prevents recurrence. Clearing septic lines of root invasion protects your entire septic system from the hydraulic stress that occurs when waste can’t reach the tank efficiently.
- Hydro-Jetting for Stubborn Blockages — When conventional drain cleaning fails to clear stubborn clogs—hardened grease accumulations, mineral buildup, or compacted debris—hydro-jetting provides the solution. We use high-pressure water jets (up to 4,000 PSI) that scour pipe interiors completely clean, removing not just clogs but the buildup that causes recurring problems. Hydro-jetting is particularly effective for septic-fed homes because it cleans pipes thoroughly without chemicals that harm septic bacteria or leave residue that accelerates new clog formation. This comprehensive cleaning restores pipes to near-new flow capacity, preventing the chronic slow drainage that stresses septic systems.
- Main Line Camera Inspection & Problem Diagnosis — Finding sewer line problems traditionally required expensive excavation—digging trenches hoping to locate breaks, root intrusion, or blockages. Our camera inspection service eliminates this guesswork by sending video cameras through sewer lines, revealing exact problem locations and conditions. We identify breaks and their severity, locate root intrusion points, find areas of pipe deterioration, document blockages and their composition, and assess overall line condition. This diagnostic precision allows targeted repairs—excavating only where necessary rather than digging entire line lengths hoping to find problems. Camera inspections also provide documentation for real estate transactions, showing buyers exact sewer line condition and helping sellers address issues proactively.
- Water Heater Service & Plumbing Repairs — Beyond sewer line specialization, we provide comprehensive plumbing services that York County homeowners need: water heater installation, repair, and replacement for tank and tankless systems; fixture repairs and replacements for leaking faucets, running toilets, and worn components; leak detection and repair for hidden water waste; and general plumbing maintenance that prevents small problems from becoming expensive emergencies. We’re the single plumbing contractor York County trusts for everything from routine repairs to critical sewer line work.

Why York County Chooses Doan Sun Plumbing LLC (5.0 Stars)
Perfect 5.0-Star Rating Built on Elite Professionalism — Our perfect rating is built on clean work, honest pricing, and the technical skill to handle the complex sewer issues other plumbers avoid. We don’t leave properties damaged from unnecessary excavation, we don’t upsell pipe replacement for problems requiring simple repairs, and we don’t disappear after payment leaving homeowners to deal with warranty issues. We complete jobs professionally—protecting landscaping during excavation, cleaning work areas thoroughly, testing repairs before considering work complete, and standing behind our work with legitimate warranties backed by a company that will be here when you need us.
Technical Expertise Other Plumbers Avoid — Sewer line work requires specialized equipment, diagnostic capability, and experience that general plumbers often lack. Many contractors avoid sewer line jobs entirely or attempt them with inadequate equipment and limited expertise—leaving homeowners with temporary fixes that fail quickly or unnecessary excavation that costs thousands more than targeted repairs. We specialize in sewer line work using professional camera inspection equipment that pinpoints problems, hydro-jetting capability that clears stubborn blockages, pipe repair expertise for both traditional and trenchless solutions, and the diagnostic skill to recommend appropriate repairs based on actual conditions rather than maximizing invoice totals.
Protecting Your Septic System Through Proper Plumbing — We understand the critical connection between indoor plumbing and outdoor septic health because we work on both daily. A broken sewer line doesn’t just create yard problems—it forces septic tanks to receive waste improperly, accelerates drainfield saturation, and causes hydraulic overload that destroys systems prematurely. We prevent these cascading failures by maintaining sewer line integrity, clearing drains before they create septic stress, removing root intrusion before it causes complete blockages, and identifying problems early through camera inspections before they require emergency repairs.
Honest Diagnosis & Transparent Pricing — When we camera inspect your sewer line, we show you exactly what we find—providing video documentation of problems rather than verbal descriptions you must trust without verification. When we quote repairs, we explain what work is necessary, what’s optional, and what can wait—giving you the information to make informed decisions rather than pressuring immediate approval of maximum-scope work. This transparency builds the trust that earns perfect ratings: homeowners appreciate contractors who treat them like intelligent adults capable of understanding their own plumbing problems and making appropriate repair decisions.
