Answers to the most frequently asked plumbing questions from O'Fallon homeowners.
Your main water shutoff valve in O'Fallon 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.
In O'Fallon, homeowners insurance typically covers sudden and accidental plumbing damage such as a burst pipe flooding your home. The cost of repairing the pipe itself may not be covered, but the resulting water damage often is. Gradual leaks and corrosion from neglected maintenance are usually excluded. Call (844) 618-0753 if you need documentation for a claim.
Plumber rates in O'Fallon 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.
Chemical drain cleaners can damage older pipes in O'Fallon 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.
Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in O'Fallon. 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 O'Fallon and surrounding Illinois communities.
Low water pressure in O'Fallon homes is often caused by mineral deposits clogging aerators and pipes, a partially closed shutoff valve, a failing pressure regulator, or a hidden water line leak. Corroded or deteriorated pipes in older O'Fallon properties can also restrict flow significantly. A licensed plumber can diagnose the specific cause and recommend the right fix.
