Garbage Disposal

Garbage disposal repair, replacement, and installation for kitchen sinks. We fix jammed, leaking, and failed units — or install new disposals with proper P-trap and dishwasher connections.

Reliable toilet repair and installation for running toilets, phantom flushes, rocking toilets, weak flushes, and leaking seals. We diagnose the root cause and repair or replace components quickly and affordably.

Gas Leak Detection

Professional gas leak detection using calibrated detectors and pressure testing to find leaks in gas lines, connections, appliances, and meters. We locate the leak source precisely and recommend repairs immediately.

Sewer Camera Inspection

Professional sewer camera inspection to diagnose blockages, root intrusion, cracks, offsets, and collapse. We show you the video so you can see the problem and make informed decisions about repairs.

Gas Line Repair

Professional gas line repair performed by licensed plumbers who understand gas system safety. We find the leak, repair or replace the damaged section, and pressure test the line before restoring gas service.

Slab Leak Repair

Slab leaks are hidden under your concrete foundation and can cause thousands in damage if left untreated. Our licensed plumbers locate and repair slab leaks quickly with minimal disruption to your home.

Tankless Water Heater Installation

Upgrade to on-demand hot water with professional tankless water heater installation. Our plumbers assess household demand, recommend the right model, and install with all required gas or electrical connections.

Leak Detection

Professional leak detection services that pinpoint hidden water leaks without tearing into walls or floors. We use non-invasive technology to find the source precisely, then recommend the most effective repair.

Emergency Plumber

When a plumbing crisis hits, you need a licensed plumber immediately. We answer emergency calls around the clock and dispatch crews fast — stopping leaks, restoring water service, and preventing further damage.

Hydro Jetting

When snaking is not enough, hydro jetting clears the pipe completely. Our professional jetters use pressurized water to blast away grease, scale, and root intrusion — restoring full pipe capacity for years.

Sump pump installation and replacement for basements and crawl spaces prone to flooding. We size the right pump, install primary and battery-backup units, and ensure reliable operation before every rainy season.

Backflow Testing

Annual backflow testing and prevention device installation for residential and commercial properties. Our certified testers verify your backflow preventer and handle compliance paperwork with your water authority.

Frequently Asked Questions

Answers to the most frequently asked plumbing questions from Hanover homeowners.

What is trenchless sewer repair and is it right for my Hanover home?

Trenchless sewer repair in Hanover 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.

How do I shut off my water in a plumbing emergency in Hanover?

Your main water shutoff valve in Hanover 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.

What plumbing emergencies require immediate service in Hanover?

Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in Hanover. 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 Hanover and surrounding New Hampshire communities.

How long does a plumbing repair take in Hanover, NH?

Simple repairs like faucet replacement, toilet repair, or drain clearing in Hanover often take 1 to 2 hours. More complex jobs like slab leak repair, water line replacement, or water heater installation typically take a half to a full day. Whole-home repiping can take 2 to 4 days. Magnet Plumbing provides a clear time estimate before starting any job.

When should I replace my water heater in Hanover, NH?

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 Hanover homeowners decide between repair and replacement.

What should I do if I smell gas in my Hanover home?

If you smell gas in your Hanover 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.
