Storm Season Water Emergency Checklist for Snohomish County Homeowners

When a strong winter storm hits Snohomish County, homeowners can lose more than electricity. Heavy rain can saturate the ground, overwhelm drainage systems, flood basements, and put extra pressure on sump pumps. If your home depends on a private well, a power outage can also mean losing water until electricity returns.

The good news is that many storm-related water problems can be reduced with a little preparation. Testing your sump pump before the rainy season, checking your well pump system, having backup power plans, and keeping emergency drinking water on hand can make a major difference when conditions get rough.

Storm Season Home Water Emergency Checklist

A storm season home water emergency checklist should cover both water supply and water removal. For homes with private wells, a power outage can stop the well pump even when the well itself is working normally. At the same time, heavy rainfall can saturate the soil and increase the amount of water entering a basement or crawl space, making a sump pump work harder. Before a major storm, homeowners should test the sump pump, inspect the discharge line, confirm that backup equipment is working, and make sure they know how to safely shut off electrical systems if flooding occurs. It is also smart to store emergency drinking water and reduce unnecessary water use during a prolonged outage. Never operate a gasoline generator indoors or in a garage. If floodwater reaches electrical equipment, do not enter the water to operate switches. Snohomish County recommends having emergency supplies, water, flashlights, batteries, and a way to receive local alerts during major events.

How Winter Storms Affect Wells and Sump Pumps

Winter storms can create two separate problems for homeowners: you may have too much water around the house while having no running water inside it.

That sounds contradictory, but it happens frequently during power outages and heavy rainfall.

A private well depends on an electric pump to move groundwater into the home. Meanwhile, a sump pump needs electricity to remove groundwater and stormwater that enters the basement or sump pit.

Snohomish County identifies severe weather and flooding among the hazards local residents should prepare for, and the county provides specific flood-preparation resources for homeowners.

Losing Water When the Power Goes Out

If your home uses a private well, the well pump normally needs electricity to operate.

So when the power goes out, you may suddenly have no water at the faucets even though the well itself has plenty of water.

You might notice:

  • No water coming from faucets
  • Little or no pressure
  • Toilets that do not refill normally
  • A pressure tank that does not cycle
  • No water from showers or appliances

This doesn’t automatically mean the well pump has failed.

In many cases, the pump simply cannot operate without power. Once electricity returns, the system should normally be able to resume operation, but a storm-related electrical problem or pre-existing pump fault can complicate the restart.

If your power has returned and you still have no water, check the system’s electrical supply only if it is safe to do so. If the pump still won’t run, professional well pump troubleshooting may be needed.

Specialty Pump & Well provides well pump repair in Snohomish, including electrical inspection, pressure switch problems, submersible pump diagnostics, pressure tank service, and emergency repairs.

Saturated Ground and Overloaded Pumps

Heavy rain creates a different challenge.

When soil becomes saturated, water has fewer places to go. More groundwater can reach the foundation and drainage system, while surface water can collect around the home.

That means a sump pump may run much more frequently than it normally does.

A sump pump that runs continuously during heavy rain isn’t necessarily broken. However, constant operation can expose problems that might otherwise remain unnoticed.

For example, the pump may be working but the discharge pipe could be restricted. A float switch could also become stuck, or the pump may simply be too small for the amount of water entering the pit.

If the pump stops during a major storm, basement flooding can happen quickly.

Specialty Pump & Well provides sump pump repair and replacement services in Snohomish, including troubleshooting for drainage problems, power issues, and unusual pump noises.

Your Pre-Storm Preparation Checklist

The best time to discover a bad pump is before the storm arrives.

You don’t want the first test of your backup system to happen when rain is already entering the basement.

Snohomish County recommends preparing before flood events and provides residents with flood-safety information covering preparation, response, and recovery.

Testing Pumps and Backup Systems

Before the storm season gets serious, walk through your water emergency checklist.

Start with the sump pump.

Pour enough water into the sump pit to raise the float and confirm that the pump starts. Watch the discharge point outside and make sure water is actually being moved away from the foundation.

If the pump starts but only produces a weak flow, that’s worth investigating.

Also check the discharge line. Make sure it isn’t crushed, blocked, disconnected, or positioned so that discharged water simply flows back toward the foundation.

If you have a battery backup sump pump, test that system separately.

For a private well, make sure you know where the pump’s electrical controls, pressure tank, and main water shutoff are located. If the system has previously shown low pressure, short cycling, unusual noises, or intermittent water loss, it’s better to address those issues before the next major storm.

A simple preparation check can look like this:

 

System What to check before a storm
Sump pump Test operation and float switch
Backup pump Test battery and automatic switchover
Discharge pipe Check for blockage or disconnection
Well pump Look for existing pressure or electrical problems
Pressure tank Watch for unusual cycling or pressure loss
Generator Test according to the manufacturer’s instructions
Emergency water Check stored water and containers
Alerts Make sure local storm and outage notifications are enabled

Storing Emergency Water

If your home depends on a private well, storing emergency drinking water is particularly useful during extended outages.

Snohomish County’s preparedness guidance recommends keeping emergency supplies, including water, available for major events. A county preparedness document has previously recommended at least two gallons of water per person per day for emergency supplies.

You don’t need to wait for a storm warning to build your supply.

Keep drinking water in clean, food-safe containers and replace stored water according to the manufacturer’s or public-health guidance for the container.

Remember that emergency water isn’t just for drinking. If the outage lasts, you may also need water for basic food preparation and hygiene.

What to Do During a Power Outage

When the power goes out during a storm, your first priority is safety.

Your well pump and sump pump may both stop working at the same time. That can create an unusual situation: your home may have no running water while water is accumulating around the foundation.

Don’t start troubleshooting electrical equipment in wet conditions.

Generator Safety with Well Pumps

A generator can potentially provide power for a well pump or sump pump, but connecting a generator to household electrical circuits is not a DIY job unless the system has been properly designed and installed for backup power.

An improperly connected generator can send electricity back through utility lines and create a serious hazard for utility workers.

If your generator is connected to your home, it should use the appropriate transfer equipment installed by a qualified professional.

Portable generators also create a carbon monoxide risk.

The CDC says generators should be operated outside and more than 20 feet from doors, windows, and vents. They should never be operated inside a home, basement, garage, or other enclosed space.

That matters during Snohomish’s winter storms because people may be tempted to move generators into garages to protect them from rain.

Don’t.

Keeping the generator dry must never mean operating it indoors. Follow the manufacturer’s instructions for safe placement and weather protection.

Reducing Water Use Until Power Returns

If your home uses a private well and the pump has stopped because of an outage, conserve whatever water you have available.

Avoid unnecessary showers, laundry, dishwashing, and other high-volume uses.

If you have stored water, prioritize drinking, cooking, medication needs, and basic hygiene.

If the power returns but your well pump doesn’t restart, don’t repeatedly reset breakers or keep cycling equipment without knowing why it failed.

A storm can expose an existing electrical or pump problem. Specialty Pump & Well notes that no water, low pressure, unusual pump sounds, and continuously running pump motors can indicate problems that need professional attention.

What to Do If Your Basement Floods

A flooded basement requires more than simply getting the water out.

Electricity and standing water can be a dangerous combination.

Snohomish County’s 2025 flood recovery guidance specifically warns residents not to enter a flooded basement and provides instructions for dealing with electrical hazards after flooding.

If water has entered the basement:

  1. Stay out of standing water if electrical equipment may be energized.
  2. Don’t touch electrical switches while standing in water.
  3. If the main electrical shutoff is only accessible through standing water, contact a qualified electrician.
  4. Keep children and pets away from the flooded area.
  5. Don’t operate a gasoline-powered generator or pump inside the home or garage.
  6. Once the area is safe, determine whether the sump pump or drainage system has failed.

The CDC similarly advises never turning electrical power on or off while standing in water and recommends professional electrical inspection when floodwater has affected electrical systems.

If sewage or contaminated floodwater has entered the basement, additional cleanup precautions are necessary.

When to Call for Emergency Service

Not every pump problem needs an emergency visit in the middle of the night.

But some situations should not be left until morning.

Situations That Can’t Wait Until Morning

Consider calling for emergency pump service when:

  • Your only source of household water has stopped working
  • A well pump fails after power has returned
  • A sump pump has stopped during active flooding
  • Water is rapidly entering the basement
  • The sump pump is running but cannot keep up
  • A pump is making loud or unusual mechanical noises
  • A pressure tank or pump is leaking
  • A pump repeatedly trips its electrical protection
  • A backup pump has also failed
  • The water system has suffered storm-related damage

If the problem is simply that the neighborhood has lost electricity, a pump technician may not be able to restore water until utility power returns.

But if the outage is over and your pump still won’t operate, the situation is different.

Specialty Pump & Well states that it provides emergency and same-day well pump service, including troubleshooting, electrical inspection, pressure switch replacement, pressure tank repair, and pump replacement.

What Same-Day Service Covers

Emergency pump service isn’t necessarily limited to replacing the entire pump.

A technician can first identify what has actually failed.

Depending on the system, that may include checking:

  • Electrical supply
  • Pressure switch
  • Pump controls
  • Pressure tank
  • Well pump
  • Float switches
  • Sump pump
  • Discharge piping
  • Backup pump
  • Other related components

The goal is to identify the cause rather than automatically replacing equipment that may still be usable.

Specialty Pump & Well says it stocks common parts and can complete many well pump repairs the same day, although larger pump pulls or replacements can require additional work.

A Simple Storm-Ready Water Plan

Storm preparation doesn’t have to be complicated.

Before the next major weather event, spend a little time checking the systems that keep water moving into and out of your home.

Test the sump pump. Check the discharge line. Test backup equipment. Know where your well pump controls and water shutoff are located. Keep emergency water available. Make sure your phone is charged and that you can receive local emergency and power-outage alerts.

Snohomish County encourages residents to stay informed through local emergency notifications and preparedness resources, including SnoCoAlerts.

Most importantly, don’t wait for standing water or a complete loss of water before taking pump problems seriously.

Frequently Asked Questions

1. What happens to my well when the power goes out?

The well itself doesn’t necessarily stop producing water. However, the electric pump that moves water from the well into your home generally cannot operate without power. As a result, you may have no running water or very low pressure until electricity is restored or an appropriate backup power system is safely used.

2. How do I prepare my sump pump for a storm?

Test the pump before the storm, make sure the float can move freely, check the discharge pipe for blockages, and confirm that water is being discharged away from your foundation. If you have a battery backup pump, test its operation and battery condition as well.

3. Can I run my well pump on a generator?

Potentially, but the generator must have enough capacity for the pump and must be connected safely. Do not improvise a connection to your home’s electrical system. A properly installed transfer switch or other approved equipment may be required. Portable generators must also be operated outdoors and more than 20 feet from doors, windows, and vents to reduce carbon monoxide risk.

4. What should I do if my basement floods?

Stay out of standing water if electrical equipment may be energized. Do not operate electrical switches or equipment while standing in water. If the electrical shutoff cannot be reached safely, contact a qualified electrician. Once the area has been declared safe, the source of the water and condition of the sump pump should be evaluated.

5. How much emergency water should I store?

Snohomish County preparedness guidance has recommended at least two gallons of water per person per day for emergency supplies. For a longer outage, households may want to store more based on the number of people, pets, medical needs, and expected access to outside supplies.

6. Is emergency pump repair available at night?

Specialty Pump & Well states that it provides 24-hour emergency service and same-day well pump repair in Snohomish. Availability can depend on the nature of the emergency and current service conditions.
