Corroded Drain Pipe Replacement in Cupertino, CA
Older homes in Cupertino often have galvanized steel or cast iron drain pipes that are prone to internal corrosion and rust, leading to leaks and reduced flow. FBL Plumbing specializes in replacing these corroded sections with modern, non-corrosive PVC or ABS piping. Our process involves carefully removing the damaged sections and cleanly tying in new, long-lasting materials, restoring your drain's integrity and preventing future failures. We make sure all connections are secure and leak-proof.

Corroded Drain Replacement in Cupertino, CA
Even good-quality water can contribute to corrosion in older metal drain pipes, especially under sinks where cleaning chemicals are often used. If you notice green or blue stains, flaking metal, or persistent leaks around your drain, it's a clear sign of corrosion. We specialize in replacing corroded metal drains with modern, durable PVC or ABS plastic systems that are resistant to chemical degradation and rust, providing a long-term solution in Cupertino, CA.
Choosing Drain Material & Brands in Cupertino, CA
When replacing a sink drain, homeowners have choices in materials like PVC, ABS, and occasionally brass or chrome-plated steel. PVC and ABS are popular for their durability and corrosion resistance, while brass offers a more traditional look. FBL Plumbing works with trusted brands like Moen, Delta, Kohler, and Plumb Pak for drain assemblies and components. We'll help you select the best material and brand for your specific sink type and budget in Cupertino, CA.
Leaking Drain Assembly Repair & Replacement in Cupertino
A leaking sink drain assembly, whether from a loose connection, a cracked pipe, or failed seals, can cause significant damage to cabinets and flooring. Our plumbers are adept at diagnosing the exact source of the leak and determining if a repair is sufficient or if a full replacement of the drain components is necessary. We ensure all connections are properly tightened and sealed with plumber's putty or silicone to prevent future leaks under your Cupertino sink.
Trap Arm and Wall Drain Repair in Cupertino, CA
When a leak comes from where the drain enters the wall, the trap arm or the stub may be cracked or corroded. Older homes sometimes have galvanized drain stubs that rust from the inside. We cut back to sound pipe and transition to new PVC or ABS with approved fittings. This keeps the trap properly vented and draining.

P-Trap Replacement in Cupertino
Traps fail from cracks, corrosion and repeated clog clearing. We replace old chrome or thin plastic traps with heavy-wall PVC or polished brass that matches exposed plumbing. Each trap is sized correctly and aligned so slip joints seal without strain. A new trap is one of the most cost-effective fixes under a sink.

Generally, simple like-for-like sink drain component replacements, such as a P-trap or tailpiece, do not need a permit in Cupertino. However, if the work involves altering the main drain lines, relocating the sink, or making significant changes to the plumbing system, a permit may be necessary. Our plumbers are knowledgeable about local codes and will advise you if a permit is required.
A sewer odor usually means a dry or improperly installed trap, or a venting problem. We check the trap seal and vent when we replace any drain.
