Frequently Asked Questions About Plumbers in 94403 (San Mateo)

First, locate and turn off your property's main water shutoff valve (usually situated in the basement, utility closet, or near the water meter) to stop active water flow. Next, open a low-level faucet to relieve residual water line pressure. Turn off electrical power to any flooded areas at the breaker panel, avoid using plumbing fixtures, and call 877-410-0321 for live safety instructions while our technician is en route.
Yes, whole-home repiping is one of our specialties. Galvanized iron pipes naturally rust from the inside out, restricting water flow and causing brown or metallic-tasting water. Our plumbers replace old supply systems with flexible, corrosion-proof PEX or durable copper tubing, completing most residential repipes with minimal drywall disruption in just 1 to 2 days.
Yes, we use advanced waterproof, self-leveling sewer inspection cameras equipped with radio sondes. We feed the camera down your main cleanout to visually inspect the interior condition of your sewer line, identifying cracked joints, pipe bellies, and invasive tree roots, and pin-pointing the exact depth and location from above ground.
Yes. Standard chemical drain cleaners often damage pipes and provide only temporary relief. Our plumbers in San Mateo utilize professional mechanical augers and high-velocity hydro-jetting equipment generating up to 4,000 PSI to pulverize grease, mineral scale, sludge, and tree root intrusions, restoring full pipe diameter permanently.
Turn the disposal switch off immediately to prevent motor burnout. A humming noise typically indicates that a foreign object or bone is jamming the impeller plate. Never place your hand into the disposal hopper. You can try pressing the red overload reset button on the bottom of the unit, or call 877-410-0321 to have a plumber in San Mateo safely unjam or replace the unit.
