Our Plumbing Services in Mill Valley

From 24/7 emergency response to complete repiping, we handle every plumbing need for homes and businesses in Mill Valley, CA.

Faucet Repair

Professional faucet repair and installation that eliminates drips, leaks, and stiff handles. We carry common repair parts on our trucks for same-visit repairs on most faucet brands, plus full installations of new fixtures.

Sump Pump Repair

Emergency sump pump repair when flooding threatens your basement or crawl space. We diagnose failed floats, clogged intakes, and seized impellers fast — getting your pump back online before water damage spreads.

Drain Cleaning

Professional drain cleaning using hydro-jetting and snaking to clear slow and clogged drains throughout your home. We remove grease, hair, roots, and mineral buildup — restoring full flow and preventing backups.

Boiler Repair

Professional boiler repair for banging noises, lost pressure, pilot failures, and circulation problems. We service atmospheric, condensing, and high-efficiency units — including expansion tanks and circulator pumps.

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.

Water Heater Repair

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.

Backflow Testing

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

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.

Tankless Water Heater Installation

Professional tankless water heater installation including new setups and tank-to-tankless conversions. We handle sizing, venting, gas supply upgrades, and permitting for code-compliant installations throughout the country.

Trenchless Sewer Repair

Professional trenchless sewer line repair for cracks, offsets, and root intrusion. Pipe lining creates a new pipe within the old one, while pipe bursting pulls a new pipe through to replace the failed line completely.

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.

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.

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.

Water Line Repair

Professional water line repair and replacement for main supply lines and service connections. We diagnose breaks, corrosion, and leaks, then perform durable repairs or full replacements using quality materials.

Emergency Plumber

Plumbing emergencies happen day and night. Our 24/7 emergency plumbers arrive quickly with the tools and materials to handle any urgent plumbing situation — protecting your property and restoring service 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.

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.

Water Heater Replacement

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 repair and replacement for cracked, collapsed, root-infiltrated, and offset pipes. We use camera inspection to diagnose the problem and recommend spot repairs, pipe lining, or full replacement.

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.

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.

Slab Leak Repair

Expert slab leak detection and repair using electronic sensors and thermal imaging to pinpoint leaks under your foundation. We perform minimally invasive repairs to protect your structure and stop water waste.

Pipe Repair

Reliable pipe repair throughout your home — from pinhole leaks in copper supply lines to cracked drain pipes and corroded fittings. We diagnose the root cause and fix the problem at the source.

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.

Hydro Jetting

Commercial and residential hydro jetting for persistent drain and sewer problems. We use calibrated pressure and nozzle selection for your specific line type, delivering a thorough clean without damaging pipes.

Frequently Asked Questions

Have questions about plumbing in Mill Valley? We have answers.

What plumbing emergencies require immediate service in Mill Valley?

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

How do I prevent frozen pipes in Mill Valley, CA?

To prevent frozen pipes in Mill Valley, 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 do I find a licensed plumber in Mill Valley, CA?

When hiring a plumber in Mill Valley, always verify their CA 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 California — call (844) 618-0753 to schedule service or get a free estimate.

Does homeowners insurance cover plumbing repairs in Mill Valley, CA?

In Mill Valley, 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 much does a plumber cost in Mill Valley, CA?

Plumber rates in Mill Valley 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.

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

Chemical drain cleaners can damage older pipes in Mill Valley 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.

★★★★★

"Once again Magnet Plumbing came to save the day. I manage a building of 49 units and we had a gas leak somewhere. The city shut the gas for the whole building. They showed up right away and got to work. They found the problem, fixed it, and were able to turn the gas back on so people could have dinner. Saul is amazing — right on time, very professional."
