Answers to the most frequently asked plumbing questions from Nashua homeowners.
Chemical drain cleaners can damage older pipes in Nashua 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.
Signs of a slab leak in Nashua 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.
To prevent frozen pipes in Nashua, 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.
Your main water shutoff valve in Nashua 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 Nashua, 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.
If you smell gas in your Nashua 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.

"Our 1970s galvanized pipes were failing one joint at a time. Got three bids on a whole-house repipe and these guys were competitive on price and had the best timeline. Seven days start to finish, minimal drywall damage, and water pressure is dramatically better throughout the house. Worth every dollar."
"Fixed a hidden leak behind the drywall without tearing apart the whole wall. Impressed with how precise they were and how quickly they found it."
"Main water line burst and we had a river in the front yard. They isolated the break, got the water back on within a few hours, and replaced the section cleanly the next day. Excellent emergency response."
