Manufactured Home Poly Replacement in Mount Pleasant, SC
Manufactured homes from the poly era often have polybutylene lines in the floor or belly. We replace these lines with PEX sized for manufactured homes and secure them properly underneath. We also check heat tape and insulation on exposed lines where winter freezes occur. Pipes in crawlspaces, exterior walls and unheated garages are the ones most likely to burst during a South Carolina cold snap, since many homes were built with little insulation around them. The result is a dependable, modern supply system.
Detecting Polybutylene Leaks in Mount Pleasant
Even small, hidden leaks from polybutylene pipes can cause significant damage to your Mount Pleasant home's foundation or interior. Our technicians use modern leak detection equipment, including acoustic sensors and thermal imaging, to pinpoint the exact location of leaks without destructive guesswork. We can identify leaks in walls, under slabs, and behind appliances, providing an honest assessment before any replacement work begins. Early detection is key to preventing widespread water damage and costly repairs in South Carolina homes.
Understanding Polybutylene Failure in Mount Pleasant
Polybutylene's inherent weakness stems from its chemical reaction with oxidants like chlorine, commonly used in municipal water treatment. Over time, this reaction causes the pipes and their plastic fittings to become brittle, leading to hairline cracks and eventual rupture. Most municipal water in South Carolina comes from rivers and reservoirs, so it tends to run fairly soft and leaves less scale than in many other states. Hard water can also add stress to pipe that is already breaking down. Understanding this failure mechanism is important for diagnosing issues and recommending the most effective and permanent replacement strategy for your home.
Polybutylene Identification and Inspection in Mount Pleasant
Polybutylene is usually gray, though it can be white, blue or black, and is often stamped PB2110. You may see it at the water heater, under sinks or near the main shutoff. We inspect visible lines, check the stamps and trace runs through the attic. You get a clear answer and a written replacement estimate.
