Have questions about plumbing in Knollwood? We have answers.
Chemical drain cleaners can damage older pipes in Knollwood 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 Knollwood. 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 Knollwood and surrounding Illinois communities.
Your main water shutoff valve in Knollwood 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.
To prevent frozen pipes in Knollwood, 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.
Signs of a slab leak in Knollwood 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.
In Knollwood, 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.

"Our older boiler was making banging noises and losing pressure. The technician diagnosed a failed expansion tank, replaced it, and the system has been silent ever since. Reasonable rate and quick turnaround."
"Amazing work. Good people. Reliable. On time and efficient. And prices are definitely hard to beat! HIGHLY RECOMMEND!"
"Smelled gas in the basement late at night and called the emergency line. A plumber was dispatched within the hour, located the leak at a corroded fitting on the water heater gas line, and repaired it on the spot. They even came back the next day to re-verify with the gas detector. Truly appreciated the care taken."
