Sump Pump Repair

Professional sump pump repair for residential and commercial properties. We diagnose electrical, mechanical, and float switch failures and return your pump to full working order with quality replacement parts.

Expert water heater repair that restores your hot water fast. From faulty thermostats and pilot light issues to anode rod replacement and sediment flushing, we fix the problem at the source for lasting results.

Repiping

Whole-home and partial repiping to replace aging galvanized, polybutylene, or deteriorated pipes with modern long-lasting materials. Repiping eliminates chronic leaks, low pressure, and discolored water permanently.

Commercial Plumbing

Commercial plumbing needs are different from residential. Our plumbers understand backflow requirements, floor drain regulations, grease trap compliance, and the scheduling demands of active business operations.

Water Line Repair

Expert water line repair using trenchless and conventional methods. We locate the break, recommend the most cost-effective repair approach, and restore your water service with minimal disruption to your property.

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.

Slab Leak Repair

Professional slab leak repair from detection through restoration. We use acoustic listening devices and thermal cameras to find the leak precisely, then repair or reroute the line to solve the problem permanently.

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.

Trenchless Sewer Repair

Trenchless sewer repair replaces damaged sewer lines without digging up your yard, driveway, or landscaping. We use pipe lining and pipe bursting methods to save time, money, and the mess of conventional excavation.

Toilet Repair

Professional toilet repair and installation. We diagnose running, leaking, rocking, and weak-flushing toilets and restore full performance with quality replacement parts. New installations handled the same way.

Sewer Camera Inspection

High-definition sewer camera inspection for residential and commercial properties. Our plumbers document the condition of your sewer line and provide a copy of the footage with our professional assessment.

Garbage Disposal

When your garbage disposal jams, leaks, or stops working, our plumbers diagnose the problem fast. We repair what makes sense and replace units that are beyond repair with quality new disposals.

Drain Cleaning

Clogged drains slow your life down. Our licensed plumbers clear kitchen drains, bathroom drains, main sewer lines, and floor drains using professional hydro-jetting equipment that cleans the entire pipe interior.

Pipe Repair

Expert pipe repair for residential and commercial properties. We locate leaks and damage accurately, perform durable repairs, and pressure test the system to confirm everything holds before leaving.

Faucet Repair

Expert faucet repair and installation for dripping, leaking, and hard-to-turn faucets in kitchens, bathrooms, and utility areas. We repair or replace cartridges, O-rings, seats, and stems — or install new fixtures.

Emergency Plumber

Around-the-clock emergency plumbing for burst pipes, slab leaks, sewer backups, gas leaks, and water heater failures. Our licensed emergency plumbers respond fast to stop damage and restore your plumbing.

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.

Water Heater Replacement

Professional water heater replacement for tank, tankless, and hybrid models. We match the right unit to your household needs and install it with all required connections, expansion tanks, and safety components.

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.

Grease Trap Cleaning

Grease trap maintenance keeps your kitchen drains flowing and your business compliant with local waste regulations. We provide scheduled pumping, manifesting, and inspection-ready documentation.

Boiler Repair

When your boiler fails in winter, you need a plumber who understands hydronic systems. Our licensed technicians diagnose and repair all major boiler brands, restoring efficient heat to your home or building fast.

Sump Pump Installation

Protect your basement before the next storm. Our plumbers install sump pumps with float switches, check valves, and battery backup systems — ready to keep groundwater out of your home reliably.

Sewer Line Repair

Professional sewer line repair that diagnoses the actual problem before recommending solutions. Camera inspection shows us exactly what is wrong so we can perform the least invasive, most cost-effective repair.

Leak Detection

Find hidden leaks before they cause serious damage. Our leak detection specialists use thermal cameras and electronic listening devices to locate leaks behind walls, under slabs, and underground with precision.

Frequently Asked Questions

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

Is it safe to use chemical drain cleaners in my Holtsville home?

Chemical drain cleaners can damage older pipes in Holtsville 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.

Does homeowners insurance cover plumbing repairs in Holtsville, NY?

In Holtsville, 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.

How do I prevent frozen pipes in Holtsville, NY?

To prevent frozen pipes in Holtsville, 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.

What causes low water pressure in Holtsville homes?

Low water pressure in Holtsville homes is often caused by mineral deposits clogging aerators and pipes, a partially closed shutoff valve, a failing pressure regulator, or a hidden water line leak. Corroded or deteriorated pipes in older Holtsville properties can also restrict flow significantly. A licensed plumber can diagnose the specific cause and recommend the right fix.

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

Your main water shutoff valve in Holtsville 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 should I replace my water heater in Holtsville, NY?

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 Holtsville homeowners decide between repair and replacement.

"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."
