Slab Leak Repair & Detection

Because the vast majority of single-family homes throughout Ontario, Rancho Cucamonga, and Chino are built on monolithic slab-on-grade concrete foundations, water supply lines were installed directly in the gravel bed beneath the concrete during initial construction. Over decades, aggressive mineral scale from local hard water combined with expansive clay soil friction creates pinhole leaks in buried copper. AVS Plumbing connects Inland Empire property owners with specialized slab leak detection and repair contractors equipped with thermal imaging and electronic acoustic listening gear.

Drain Cleaning & Clog Clearing

A slow or backed-up drain disrupts your entire household routine. In Ontario and the West Valley, drains suffer not only from everyday grease and hair accumulation, but also from heavy calcium scale narrowing pipe diameters and invasive tree roots penetrating exterior lines. AVS Plumbing connects property owners with local drain clearing specialists who utilize professional motorized cable augers and high-velocity hydro-jetters to clear blockages safely without harsh chemical damage.

Sewer Line Repair & Replacement

A damaged sewer lateral is one of the most stressful and unsanitary plumbing failures a homeowner can experience. In older neighborhoods across Ontario, Upland, and Pomona, original vitrified clay and cast iron sewer laterals installed decades ago have suffered mortar joint failure, root intrusion, and ground settling. AVS Plumbing connects property owners with sewer repair and trenchless replacement contractors who use fiber-optic video cameras, trenchless pipe bursting, and structural epoxy lining to fix sewer laterals with minimal landscape disruption.

Water Heater Repair & Replacement

Losing hot water halts laundry, dishwashing, and daily showers. In Ontario and across the Inland Empire, water heaters face aggressive operational strain from local tap water that averages 138 ppm CaCO₃ mineral hardness. Calcium carbonate precipitates at the bottom of storage tanks, creating insulating sediment blankets that overheat tank bottoms and corrode steel seams. AVS Plumbing connects property owners with local water heater repair and replacement pros for standard gas tanks, electric models, and high-efficiency tankless water heaters.

Repiping & Burst Pipe Repair

If your home is experiencing recurring pinhole leaks, rusty discolored water, or severe water pressure drops when two faucets are used at once, your plumbing infrastructure has reached the end of its useful lifespan. Older residences in Ontario, Pomona, and Upland still rely on deteriorating post-war galvanized steel or early-generation copper lines corroded by local hard water. AVS Plumbing connects property owners with repiping and burst pipe repair specialists who replace failing pipe networks with modern, flexible PEX-A or rigid Type L copper.

Gas Line Repair & Installation

Natural gas powers water heaters, furnaces, cooktops, and dryers across Ontario and the Inland Empire. However, a damaged gas line poses an immediate life-safety risk of explosion and carbon monoxide poisoning. If you suspect an active leak, evacuate immediately and notify emergency services or SoCalGas. For code-compliant repairs, seismic shutoff valve installations, and new gas line extensions for outdoor living spaces, AVS Plumbing connects property owners with qualified plumbing and pipeline contractors.
