Common questions about plumbing services in Johnston, IA.
Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in Johnston. 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 Johnston and surrounding Iowa communities.
Your main water shutoff valve in Johnston 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.
When hiring a plumber in Johnston, always verify their IA 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 Iowa — call (844) 618-0753 to schedule service or get a free estimate.
If you smell gas in your Johnston home, do not operate any electrical switches, open flames, or appliances. Leave the building immediately, leaving doors open as you go. Call your gas utility from outside or from a neighbor, then call Magnet Plumbing for emergency gas line inspection. Do not re-enter until a professional has cleared the property.
Chemical drain cleaners can damage older pipes in Johnston 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.
Most tank water heaters last 8 to 12 years. Consider replacement when your unit is over 10 years old, produces rusty or discolored water, makes rumbling or popping noises, or requires frequent repairs. Magnet Plumbing offers free water heater assessments to help Johnston homeowners decide between repair and replacement.
Honest feedback from homeowners who trusted Magnet Plumbing with their plumbing projects.
"Late-night leak under the kitchen sink, had someone out within 90 minutes. Stopped the leak, replaced the shutoff valve, and I could finally go back to sleep."
"Saul and crew are the best. Replaced our water heater, re-piped, and gassed up our kitchen and laundry room. Honest, fair, efficient, and went above and beyond. I could not have asked for a better experience. Highly recommend. Thank you!"

On time, reasonable rate, professional work and communication, great personalities, and they cleaned up when done."
