Leak Detection Sunnyvale, CA– Trusted & Timely Services

Slab Leaks

Hidden beneath the concrete base of many Sunnyvale homes, slab leaks can silently compromise structural stability if not caught early. These leaks often result from long-term pipe corrosion, soil shifting, or foundation stress, gradually weakening the home’s base. Telltale signs include rising utility bills, warm spots on floors, and unexplained mildew odors. These issues are located accurately using acoustic and electronic detection equipment operated by CPI Service, whose technicians apply non-invasive methods followed by targeted rerouting or foundation-safe repairs to prevent further damage.

Water Pipe Leaks

When water starts seeping from behind a wall or ceiling in a Sunnyvale property, the culprit is often a damaged supply line. Common causes include pressure surges, age-related corrosion, or unstable pipe joints, all of which can lead to silent but destructive leaks. If not addressed, these leaks can rot structural wood, stain interiors, and foster mold growth. Our team at CPI Service uses thermal imaging and pressure testing to identify the exact location, then performs high-precision pipe repairs that stop the leak and preserve surrounding materials.

Faucet and Fixture Leaks

Even a slow drip from a bathroom faucet or kitchen fixture can waste hundreds of gallons of water over time. These leaks typically arise from worn washers, damaged cartridges, or loose valves that degrade with use. Though often visible, their cumulative cost in water bills and fixture wear is significant. Using professional-grade replacement parts and thorough diagnostics, CPI Service ensures each repair is properly sealed and calibrated for long-term reliability.

Toilet and Shower Leaks

Silent toilet leaks and slow-draining showers are often overlooked but can lead to inflated water bills and concealed damage. Faulty flappers, leaky fill valves, or deteriorated seals in Sunnyvale homes are among the most common sources of water loss in these fixtures. Left unchecked, these leaks can promote moisture buildup behind walls or under tile. After diagnosing the source using flow rate testing and internal inspections, CPI Service completes repairs by installing upgraded parts and ensuring all connections are watertight, preventing further waste or hidden moisture buildup.

Underground Water Line Leaks

When lush patches of grass or puddling occur without explanation, it is often due to a leak in an underground water line. These issues are especially common in older Sunnyvale properties with outdated piping or expansive yards. Causes range from pipe corrosion and joint failure to root intrusion, all of which can lead to significant water waste. Through the use of tracer gas and acoustic sensors, CPI Service isolates the exact location of the breach and performs efficient trenchless or localized repairs that restore the line while preserving landscaping and hardscape features.

Drainage and Sewer Leaks

Unpleasant odors, gurgling drains, or recurring backups in Sunnyvale homes often trace back to drainage or sewer line leaks. These problems are typically caused by cracked clay pipes, corrosion, or tree root intrusion affecting the underground waste system. Such leaks pose health hazards and can lead to extensive property damage if not properly addressed. By combining video inspections with precision testing, CPI Service identifies the compromised section and offers corrective options like pipe relining, section replacement, or root removal to fully restore system function and sanitation.
