Gas Leak Detection

Accurate gas leak detection before small leaks become emergencies. We test your entire gas system using professional detection equipment and pressure gauges, identify any leaks, and perform safe code-compliant repairs.

Backflow Testing

Professional backflow prevention testing and device installation. Our certified plumbers service residential and commercial properties, protecting your potable water supply from contamination.

Sump Pump Installation

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.

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.

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.

Water line breaks can disrupt your entire home's water supply. Our licensed plumbers repair or replace damaged main lines and service connections quickly, restoring full water pressure and flow to your property.

Water heater replacement with same-day or next-day installation in most areas. We remove your old unit, recommend the right size and model for your needs, and install your new water heater to code.

Sewer Line Repair

Sewer line problems cause backups, odors, and potential health hazards. Our plumbers use video cameras to inspect the line, identify the damage, and repair or reline the pipe — often without full excavation.

Sewer Camera Inspection

Video sewer inspection reveals exactly what is happening inside your sewer line — no guesswork, no unnecessary excavation. Essential for pre-purchase inspections and diagnosing recurring sewer problems.

Grease Trap Cleaning

Professional grease trap cleaning for commercial kitchens of all sizes. Reliable schedules, full compliance paperwork, and a clean trap every time — keeping your operation running and inspection-ready.

Frequently Asked Questions

Answers to the most frequently asked plumbing questions from San Dimas homeowners.

How do I prevent frozen pipes in San Dimas, CA?

To prevent frozen pipes in San Dimas, 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.

How long does a plumbing repair take in San Dimas, CA?

Simple repairs like faucet replacement, toilet repair, or drain clearing in San Dimas 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.

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

Your main water shutoff valve in San Dimas 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 should I do if I smell gas in my San Dimas home?

If you smell gas in your San Dimas 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.

When should I replace my water heater in San Dimas, CA?

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 San Dimas homeowners decide between repair and replacement.

What plumbing emergencies require immediate service in San Dimas?

Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in San Dimas. 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 San Dimas and surrounding California communities.
