Answers to the most frequently asked plumbing questions from Smithtown homeowners.
Plumber rates in Smithtown typically range from $100 to $250 per hour depending on the type of work and time of day. Common jobs like drain cleaning run $150 to $300, while slab leak repair and repiping projects cost significantly more. Magnet Plumbing provides free estimates so you know the full cost before any work begins.
Chemical drain cleaners can damage older pipes in Smithtown 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.
Your main water shutoff valve in Smithtown 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.
To prevent frozen pipes in Smithtown, 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.
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 Smithtown homeowners decide between repair and replacement.
When hiring a plumber in Smithtown, always verify their NY 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 York — call (844) 618-0753 to schedule service or get a free estimate.
Our reputation is built on results. Here is what our customers say.
"Replaced two old toilets with new comfort-height models. The installer was respectful, took his shoes off at the door, and hauled away the old toilets. Small things that make a big difference."
"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."
"Smelled gas in the basement late at night and called the emergency line. A plumber was dispatched within the hour, located the leak at a corroded fitting on the water heater gas line, and repaired it on the spot. They even came back the next day to re-verify with the gas detector. Truly appreciated the care taken."
