Frequently Asked Questions

Common questions about plumbing services in San Antonio, TX.

How do I prevent frozen pipes in San Antonio, TX?

To prevent frozen pipes in San Antonio, 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.

What plumbing emergencies require immediate service in San Antonio?

Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in San Antonio. 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 Antonio and surrounding Texas communities.

How do I find a licensed plumber in San Antonio, TX?

When hiring a plumber in San Antonio, always verify their TX license and insurance. A licensed plumber must pass state examinations and carry liability coverage that protects your property.

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

Common jobs like drain cleaning run $150 to $300, while slab leak repair and repiping projects cost significantly more.

How can I tell if I have a slab leak in my San Antonio home?

Signs of a slab leak in San Antonio homes include unexplained increases in your water bill, warm or wet spots on the floor, the sound of running water when all fixtures are off, cracks in the foundation or walls, and low water pressure. If you notice these symptoms, call a plumber for professional slab leak detection before the damage worsens.

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

Your main water shutoff valve in San Antonio 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.
