Common Causes of Flooding in Seattle
Multiple factors increase your risk of flooding in Seattle, including heavy rainfall, drainage system overload, appliance failure, and coastal flooding. Below are the most common reasons Seattle residents and business owners require emergency water removal:
- Heavy rainfall: Seattle is known for plentiful rainfall. Heavy rains can overflow gutters, seep into basements, or enter homes through damaged roofs, resulting in leaking from ceilings.
- Snowmelt: While Seattle sees most precipitation as rain, the surrounding mountains experience heavy snowfall. Snowmelt can cause rivers to swell and break their banks.
- Drainage system overload: Seattle relies on storm drains to funnel water away from roads. Heavy rain or riverine floods can overwhelm storm drains, leaving water nowhere to go.
- Sewer line backup: Sewer line backups and overflows are common causes of basement flooding in Seattle. Contaminated wastewater causes serious property damage and poses a health risk.
- Stormwater backup: Many older homes in Seattle have floor drains that connect to residential and municipal storm drain systems. If floods or heavy rainfall overwhelm the storm drains, stormwater can back up into building basements.
- Sump pump failure: Sump pumps keep groundwater lower than a building’s basement floor. Sump pump failures can result in flooding.
- Water-based appliance malfunctions: Dishwashers, clothes washers, and water heaters may leak or suffer a water supply hose failure, causing localized flooding.
- Plumbing problems: Leaky pipes, clogged drains, burst pipes, and other plumbing equipment failures are common causes of water emergencies.

Tips for Flood Preparedness
While it's impossible to eliminate the risk of a water emergency completely, there are steps you can take to minimize flood damage. Here are some practical flood preparedness guidelines:
Assess Your Flood Risk
Assess your risk of flooding. Utilize the FEMA Flood Map Service Center to determine if your home or business is in a flood-prone area.
Check Your Insurance Policy for Flood Coverage
Standard home or business insurance policies do not cover flood damage. Contact your insurance agent to confirm you have flood insurance or to determine the appropriate level of coverage for your property if you lack coverage.
Enroll in Emergency Alert Systems
Stay informed by registering for local weather and flood alerts and notifications from the Emergency Alert System and the National Oceanic and Atmospheric Administration (NOAA) Weather Radio.
Preventative Maintenance for Floods
Roto-Rooter offers maintenance services that can enhance your plumbing system's efficiency, as regular maintenance clearing and cleaning of drains prevent blockages and similar issues. Additionally, consider learning some basic DIY plumbing skills, such as how to temporarily fix leaky pipes until a professional can repair them. Regularly test your basement sump pump by pouring a 5-gallon bucket of water into it. The sump pump should quickly turn on, pump away the water, and then turn itself off again. Consider a battery-powered backup sump pump that will work even in the event of a power failure.
Take Inventory of Your Belongings
Create a visual record of your possessions by taking photographs or videos of your home or business contents. Store this record securely online; a record of your property helps you prove ownership during insurance claims.
Safeguard Important Documents
Protect important documents such as birth certificates, medical records, wills, insurance papers, and passports by storing them in a waterproof container or renting safety deposit boxes from a bank.
Most importantly, prioritize your safety and that of your family or employees. Avoid contact with sewage water and refrain from wading through floodwaters, particularly if you suspect flood water has made contact with electricity. Evacuate to higher ground and seek professional assistance promptly.
