Our Plumbing Services in Downtown Mercer Island

Every plumbing service you need, delivered by licensed professionals who know the Downtown Mercer Island area.

Toilet Repair

A running or leaking toilet wastes thousands of gallons and drives up your water bill. Our plumbers fix flappers, fill valves, wax rings, flush handles, and other toilet components — or install new toilets.

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.

Slab Leak Repair

Slab leaks are hidden under your concrete foundation and can cause thousands in damage if left untreated. Our licensed plumbers locate and repair slab leaks quickly with minimal disruption to your home.

Tankless Water Heater Installation

Upgrade to on-demand hot water with professional tankless water heater installation. Our plumbers assess household demand, recommend the right model, and install with all required gas or electrical connections.

Backflow Testing

Backflow testing is required annually in many jurisdictions. We test your preventer, document the results, and submit paperwork to your local water authority — keeping you in compliance and your drinking water safe.

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.

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.

Boiler Repair

Boiler repair and installation for residential and commercial hydronic heating systems. We service gas, oil, and electric boilers for reliable winter heating — diagnosing pressure, circulation, and combustion issues.

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.

Sump Pump Repair

A failing sump pump during heavy rain can flood your basement in minutes. Our licensed plumbers respond quickly to repair or replace failed pumps, restore drainage, and protect your property from water damage.

Garbage Disposal

Garbage disposal repair, replacement, and installation for kitchen sinks. We fix jammed, leaking, and failed units — or install new disposals with proper P-trap and dishwasher connections.

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.

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.

Water Heater Repair

Fast water heater repair for tank and tankless units. We diagnose and fix pilot light failures, thermostat issues, heating element problems, pressure relief valve malfunctions, and sediment buildup quickly.

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.

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.

Hydro Jetting

Hydro jetting service using high-pressure water to scour the interior of your drain and sewer lines. Removes grease, scale, tree roots, and years of buildup that mechanical snaking cannot reach.

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.

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.

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.

Pipe Repair

Professional pipe repair for leaks, corrosion, and breaks in supply lines, drain lines, and waste pipes. Our licensed plumbers diagnose the cause and perform lasting repairs using quality materials.

Gas Line Repair

Licensed gas line repair for natural gas and propane systems. We use pressure testing and calibrated gas detectors to locate leaks and perform safe, code-compliant repairs to restore your gas service.

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.

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.

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

Common questions about plumbing services in Downtown Mercer Island, WA.

How do I shut off my water in a plumbing emergency in Downtown Mercer Island?

Your main water shutoff valve in Downtown Mercer Island 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.

Is it safe to use chemical drain cleaners in my Downtown Mercer Island home?

Chemical drain cleaners can damage older pipes in Downtown Mercer Island 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.

What plumbing emergencies require immediate service in Downtown Mercer Island?

Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in Downtown Mercer Island.
