Frequently Asked Questions

Have questions about plumbing in Duncan? We have answers.

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

Chemical drain cleaners can damage older pipes in Duncan 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.

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

Your main water shutoff valve in Duncan 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 do I find a licensed plumber in Duncan, SC?

When hiring a plumber in Duncan, always verify their SC 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 South Carolina — call (844) 618-0753 to schedule service or get a free estimate.

How often should I have my drains cleaned in Duncan?

Most Duncan homeowners benefit from professional drain cleaning every 1 to 2 years as preventive maintenance. Homes with large families, frequent cooking, or older plumbing may need service more often. Tree roots, grease buildup, and hair are the most common causes of drain problems in Duncan. Magnet Plumbing uses hydro-jetting and snaking to thoroughly clear all drain types.

What plumbing emergencies require immediate service in Duncan?

Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in Duncan. 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 Duncan and surrounding South Carolina communities.

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

Trenchless sewer repair in Duncan replaces damaged sewer lines using pipe lining or pipe bursting methods — without digging up your yard, driveway, or landscaping.
