Common questions about plumbing services in Alton, IL.
Chemical drain cleaners can damage older pipes in Alton 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.
When hiring a plumber in Alton, always verify their IL 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 Illinois — call (844) 618-0753 to schedule service or get a free estimate.
Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in Alton. 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 Alton and surrounding Illinois communities.
Your main water shutoff valve in Alton 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.

Signs of a slab leak in Alton 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.
