Answers to the most frequently asked plumbing questions from Dover homeowners.
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 Dover homeowners decide between repair and replacement.
Your main water shutoff valve in Dover 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 Dover, always verify their NH 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 New Hampshire — call (844) 618-0753 to schedule service or get a free estimate.
In Dover, 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.
Chemical drain cleaners can damage older pipes in Dover 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 Dover. 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 Dover and surrounding New Hampshire communities.
