High-definition sewer camera inspection for residential and commercial properties. Our plumbers document the condition of your sewer line and provide a copy of the footage with our professional assessment.

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.

Gas Leak Detection

Accurate gas leak detection before small leaks become emergencies. We test your entire gas system using professional detection equipment and pressure gauges, identify any leaks, and perform safe code-compliant repairs.

Garbage Disposal

Garbage disposal repair, replacement, and installation for kitchen sinks. We fix jammed, leaking, and failed units — or install new disposals with proper P-trap and dishwasher connections.

Slab leaks are hidden under your concrete foundation and can cause thousands in damage if left untreated. Our licensed plumbers locate and repair slab leaks quickly with minimal disruption to your home.

Sewer Line Repair

Sewer line repair and replacement for cracked, collapsed, root-infiltrated, and offset pipes. We use camera inspection to diagnose the problem and recommend spot repairs, pipe lining, or full replacement.

Frequently Asked Questions

Common questions about plumbing services in San Marcos, TX.

What plumbing emergencies require immediate service in San Marcos?

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 Texas communities.

How much does a plumber cost in San Marcos, TX?

Plumber rates in San Marcos typically range from $100 to $250 per hour depending on the type of work and time of day. Common jobs like drain cleaning run $150 to $300, while slab leak repair and repiping projects cost significantly more. Magnet Plumbing provides free estimates so you know the full cost before any work begins.

How do I shut off my water in a plumbing emergency in San Marcos?

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. If you cannot find your shutoff or it is stuck, call Magnet Plumbing immediately — our emergency crew can help locate and operate the valve to stop water damage.

How long does a plumbing repair take in San Marcos, TX?

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.

Is it safe to use chemical drain cleaners in my San Marcos home?

Chemical drain cleaners can damage older pipes in San Marcos homes, especially PVC, brass, or aging galvanized plumbing. The caustic chemicals can eat through pipe walls over time and are hazardous if they splash on skin or eyes. A professional drain cleaning by Magnet Plumbing is safer, more effective, and prevents pipe damage — costing less in the long run.

What is trenchless sewer repair and is it right for my San Marcos home?

Trenchless sewer repair in San Marcos replaces damaged sewer lines using pipe lining or pipe bursting methods — without digging up your yard, driveway, or landscaping. It works for most sewer line problems including cracks, root intrusion, and offset joints. Magnet Plumbing uses camera inspection to confirm trenchless repair is the right approach for your specific line condition.
