Why Choose Whole House Repiping or Sewer Line Replacement in North Carolina and South Carolina?
Whole house repiping replaces old, failing water supply lines, while sewer line replacement addresses the main drain carrying wastewater from your home to the city sewer or septic system. Both are critical for properties built in the 1970s–1990s, when problematic materials were common.
Common signs you need repiping, sewer replacement, or drain services:
- Frequent leaks or pinhole leaks in water lines
- Multiple slow or clogged drains
- Sewage backups in toilets, tubs, or basement drains
- Foul odors inside or outside
- Low water pressure or discolored water
- Unexplained wet spots, lush yard patches, or sinkholes
- Gurgling sounds or recurring clogs
In NC and SC, tree root intrusion, aging pipes, and soil shifting are leading causes of failure.
Repiping and sewer services from Modern Plumbing and Backflow minimize disruption and deliver long-lasting results for residential and commercial properties.
Polybutylene Pipes (Quest Piping): A Common Issue in North Carolina Homes and Businesses
Polybutylene (PB) pipes, known as Quest piping, are plastic water supply lines (gray or blue) installed from 1978 to 1995. They react with chlorinated water, becoming brittle and prone to sudden leaks or bursts—often causing severe water damage. Polybutylene pipe replacement in North Carolina remains essential for many homes built in the 1980s–early 1990s, especially in Raleigh-Durham, Cary, and the Upstate SC areas of Greenville and Spartanburg.
Insurance companies often flag polybutylene pipes, leading to higher premiums or coverage issues. Proactive replacement restores insurability.
CPVC Pipes: Brittleness and Long-Term Risks
CPVC pipes, used for hot and cold water lines, become brittle over 20–30 years as plasticizers leach out. Factors like heat, chemicals, and pressure cause cracking and failures—a “ticking time bomb” in older homes. CPVC repiping prevents unexpected bursts and extensive damage in Spartanburg, Greenville, Raleigh, and Durham properties.
Sewer Line and Main Drain Replacement Services
The main sewer line (or lateral) carries all wastewater from your home. Common failures include tree root intrusion, collapsed pipes, corrosion, bellies (low spots), or blockages from grease and debris.
We offer:
- Free sewer camera inspections to accurately diagnose issues
- Trenchless sewer replacement options (pipe lining or pipe bursting) for minimal yard disruption
- Traditional excavation when needed for severe damage
- Full main drain line replacement for lasting reliability
Trenchless methods are faster and less invasive, ideal for most Raleigh-Durham and Greenville-Spartanburg homes.
