Complete Residential & Commercial Plumbing Services
Mercer Island is an exceptional community nestled in Lake Washington, featuring distinctive topographical terrain ranging from elevated ridgelines along Island Crest Way to waterfront properties on East and West Mercer Way. The island's housing stock reflects decades of Northwest architectural development, predominantly custom homes constructed between the 1950s and 1980s, alongside newer luxury residences and vibrant Town Center multi-family condominiums.
These diverse structural configurations and island environmental factors—such as heavy winter rainfall, high water tables along shoreline properties, steep hillsides, and dense canopies of mature cedar and Douglas fir trees—create unique demands on plumbing infrastructure. Aging galvanized water lines corrode from the inside out, vintage clay or concrete side sewers suffer aggressive tree root penetration, and water heaters work continuously against cool incoming water temperatures.
At Washington Plumbing, we provide an extensive roster of specialized plumbing services tailored specifically to Mercer Island's geographic and architectural conditions. Below is an overview of our core services:
Our Core Specialized Plumbing Services
1. Water Heater Repair
When hot water systems fail, our technicians diagnose gas pilots, electric elements, thermostats, and internal sediment scale. Serving all single-family homes and Town Center condos, we quickly return warmth and comfort to your home.
2. Emergency Plumbing
Uncontrolled burst pipes, overflowing toilets, active main line fractures, and sudden sewer backups demand immediate technical action. We provide swift telephone dispatch to guide shutoffs and resolve critical plumbing disasters promptly.
3. Drain Cleaning
Sluggish sinks, bubbling showers, and stubborn toilet stoppages are expertly cleared using heavy-duty electro-mechanical snakes and specialized rotary cutters that thoroughly eliminate soap scum, hair clogs, and kitchen grease buildup.
4. Water Heater Replacement
When aging storage tanks begin leaking or pass their 10-year lifespan, we install high-efficiency gas, electric, and hybrid heat pump units fully compliant with Washington State seismic strapping and expansion tank codes.
5. Side Sewer Repair
Mercer Island property owners are responsible for maintaining the side sewer line from the foundation to the public main connection. We provide trenchless CIPP lining, spot repairs, and complete replacements for failing clay or concrete laterals.
6. Leak Detection
Unexplained spikes in water bills, damp drywall, or warm spots on flooring indicate concealed leaks. Our non-invasive acoustic sensors and thermal imaging cameras locate hidden slab leaks and in-wall pipe ruptures without unnecessary destruction.
7. Sump Pump Service
Low-lying properties near Lake Washington and hillside basements require dependable sump pumps to combat high groundwater and heavy winter rains. We service, replace, and install primary submersible pumps and reliable battery backup systems.
8. Tankless Water Heaters
Enjoy continuous on-demand hot water and maximize basement or utility room square footage with high-efficiency condensing tankless units. We handle gas supply line sizing, expert installations, venting, and annual mineral descaling.
9. Whole House Repiping
Older homes with decaying galvanized iron or deteriorating early copper pipes suffer from low water pressure and rusty tap water. We replace obsolete plumbing with premium PEX-a or Type L copper, dramatically improving water quality and pressure.
10. Sewer Camera Inspection
Eliminate guesswork before purchasing real estate or addressing recurrent drainage backups. Our high-definition color optical scopes inspect the interior condition of your sewer lateral, revealing offsets, bellies, and root intrusions.
11. Hydro Jetting
When standard snaking cannot penetrate heavy root masses, thick grease blankets, or stubborn mineral scale, hydro jetting utilizes 4,000 PSI high-velocity water jets to blast interior pipe walls completely clean down to the bare pipe wall.
