What to Do During a Plumbing Emergency
Shut Off the Water
Know where your main water shut-off valve is located. In Mercer Island homes, this is typically where the water line enters your house. Turning it off stops water flow and prevents further damage.
Turn Off Your Water Heater
If there's significant water loss, turn off your water heater to prevent damage. For gas water heaters, turn the gas valve to "pilot" or "off."

Mercer Island-Specific Emergency Considerations
Multi-Era Housing Stock
Mercer Island has homes from nearly every era of the past 80+ years:
Mid-Century Homes (1940s-1960s):
- Original copper and cast iron plumbing
- Galvanized water supply lines in some properties
- Plumbing systems 60-80 years old
- Many have been partially updated over the decades
1970s-1990s Construction:
- Mix of original and updated plumbing
- Water heaters likely on second or third replacement
- Some original fixtures and valves remaining
Newer and Remodeled Homes:
- Modern plumbing systems
- High-end fixtures and equipment

Waterfront Properties
Mercer Island's waterfront homes face unique considerations:
- Higher groundwater levels
- Sump pump dependency for some properties
- Lake-level fluctuations can affect drainage
- Premium finishes requiring careful work
Soft Water Conditions
Mercer Island receives soft water from Seattle Public Utilities, similar to Bellevue. While easy on pipes, soft water is aggressive on water heater anode rods. Proper monitoring prevents premature tank failure.
