Answers to the most frequently asked plumbing questions from Goffstown 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 Goffstown homeowners decide between repair and replacement.
In Goffstown, 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.
Your main water shutoff valve in Goffstown 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 Goffstown, 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.
To prevent frozen pipes in Goffstown, 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.
Trenchless sewer repair in Goffstown replaces damaged sewer lines using pipe lining or pipe bursting methods — without digging up your yard, driveway, or landscaping. It works for most sewer line problems including cracks, root intrusion, and offset joints. Magnet Plumbing uses camera inspection to confirm trenchless repair is the right approach for your specific line condition.
