Your local plumbing experts in San Marcos, CA. From emergency response to full repiping, we handle it all.
Our licensed California plumbers provide a complete range of plumbing services for San Marcos homeowners and businesses.
Gas leaks are a serious safety hazard. Our licensed plumbers use professional gas detection equipment to find leaks in supply lines, fittings, appliances, and meters — and recommend immediate repairs to protect your family.
Professional sump pump repair for residential and commercial properties. We diagnose electrical, mechanical, and float switch failures and return your pump to full working order with quality replacement parts.
Expert faucet repair and installation for dripping, leaking, and hard-to-turn faucets in kitchens, bathrooms, and utility areas. We repair or replace cartridges, O-rings, seats, and stems — or install new fixtures.
Around-the-clock emergency plumbing for burst pipes, slab leaks, sewer backups, gas leaks, and water heater failures. Our licensed emergency plumbers respond fast to stop damage and restore your plumbing.
A running or leaking toilet wastes thousands of gallons and drives up your water bill. Our plumbers fix flappers, fill valves, wax rings, flush handles, and other toilet components — or install new toilets.
Professional tankless water heater installation including new setups and tank-to-tankless conversions. We handle sizing, venting, gas supply upgrades, and permitting for code-compliant installations throughout the country.
Trenchless sewer repair replaces damaged sewer lines without digging up your yard, driveway, or landscaping. We use pipe lining and pipe bursting methods to save time, money, and the mess of conventional excavation.
Boiler repair and installation for residential and commercial hydronic heating systems. We service gas, oil, and electric boilers for reliable winter heating — diagnosing pressure, circulation, and combustion issues.
Professional grease trap cleaning for commercial kitchens of all sizes. Reliable schedules, full compliance paperwork, and a clean trap every time — keeping your operation running and inspection-ready.
Professional gas line repair performed by licensed plumbers who understand gas system safety. We find the leak, repair or replace the damaged section, and pressure test the line before restoring gas service.
Expert water line repair using trenchless and conventional methods. We locate the break, recommend the most cost-effective repair approach, and restore your water service with minimal disruption to your property.
Professional commercial plumbing services for all business types. From emergency repairs that keep your doors open to scheduled maintenance that prevents downtime, we protect your business operations.
Professional sewer line repair that diagnoses the actual problem before recommending solutions. Camera inspection shows us exactly what is wrong so we can perform the least invasive, most cost-effective repair.
Thorough drain cleaning that goes beyond surface blockages. We use video inspection and high-pressure water jetting to clear obstructions completely, leaving your drains flowing freely and reducing future buildup.
Whole-home and partial repiping to replace aging galvanized, polybutylene, or deteriorated pipes with modern long-lasting materials. Repiping eliminates chronic leaks, low pressure, and discolored water permanently.
No hot water? Our licensed plumbers diagnose and repair water heater problems on the first visit whenever possible. We service all major tank and tankless brands and carry common repair parts on our service vehicles.
Video sewer inspection reveals exactly what is happening inside your sewer line — no guesswork, no unnecessary excavation. Essential for pre-purchase inspections and diagnosing recurring sewer problems.
Professional slab leak repair from detection through restoration. We use acoustic listening devices and thermal cameras to find the leak precisely, then repair or reroute the line to solve the problem permanently.
Advanced leak detection using thermal imaging, electronic sensors, and pressure testing to find hidden leaks in walls, floors, and underground. Accurate detection prevents costly water damage and unnecessary demolition.
Protect your basement before the next storm. Our plumbers install sump pumps with float switches, check valves, and battery backup systems — ready to keep groundwater out of your home reliably.
Hydro jetting service using high-pressure water to scour the interior of your drain and sewer lines. Removes grease, scale, tree roots, and years of buildup that mechanical snaking cannot reach.
Reliable pipe repair throughout your home — from pinhole leaks in copper supply lines to cracked drain pipes and corroded fittings. We diagnose the root cause and fix the problem at the source.
Professional garbage disposal installation and repair. We handle electrical connections, mounting flange replacement, and drain line connections for reliable, leak-free kitchen sink drainage.
Backflow testing is required annually in many jurisdictions. We test your preventer, document the results, and submit paperwork to your local water authority — keeping you in compliance and your drinking water safe.
Water heater replacement with same-day or next-day installation in most areas. We remove your old unit, recommend the right size and model for your needs, and install your new water heater to code.

Your main water shutoff valve in San Marcos is typically located near the water meter, near the front foundation, or in the basement or utility room. Turn the valve clockwise to close it.

Simple repairs like faucet replacement, toilet repair, or drain clearing in San Marcos often take 1 to 2 hours. More complex jobs like slab leak repair, water line replacement, or water heater installation typically take a half to a full day. Whole-home repiping can take 2 to 4 days. Magnet Plumbing provides a clear time estimate before starting any job.
Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in San Marcos. A burst pipe can release hundreds of gallons per hour, and gas leaks pose fire and explosion risks. Magnet Plumbing provides 24/7 emergency plumbing service throughout San Marcos and surrounding California communities.
When hiring a plumber in San Marcos, always verify their CA license and insurance. A licensed plumber must pass state examinations and carry liability coverage that protects your property. Magnet Plumbing employs licensed, background-checked plumbers throughout California — call (844) 618-0753 to schedule service or get a free estimate.
Most tank water heaters last 8 to 12 years. Consider replacement when your unit is over 10 years old, produces rusty or discolored water, makes rumbling or popping noises, or requires frequent repairs. Magnet Plumbing offers free water heater assessments to help San Marcos homeowners decide between repair and replacement.
To prevent frozen pipes in San Marcos, insulate exposed pipes in unheated areas like garages, crawl spaces, and attics. Keep cabinet doors under sinks open during cold snaps. Let faucets drip slightly during freezing temperatures. If a pipe does freeze, call Magnet Plumbing immediately rather than attempting to thaw it yourself to avoid a burst.
