• Consider a battery backup system for power outages

Improve yard drainage

Proper landscaping can direct water outside from your home:

• Ensure the ground slope outside from your foundation (6 inches of fall over 10 feet )
• Creates wales (shallow ditches )to channel water
• Install rain gardens to absorb excess water
• Use permeable materials for patios and walkways

Prevent backflow from drains and pipes

DIY drain covers

When sewers backward up, floor drains become entry points for contaminate water:

• 
  Temporary plugs:
  
  1. Purchase rubber drain plugs in appropriate sizes
  2. Insert securely into drains when flooding threaten
  3. For a makeshift solution, place a rubber mat over the drain and weigh it down

Toilet backflow prevention

Toilets can be sources of backflow during floods:

• Turn off water to toilets
• Cover bowl with plastic wrap, secure with waterproof tape
• Place a weight on top
• For long term protection, install a backflow valve in the main line

Check valve installation

Check valves prevent sewer water from flow backward into your home:

• Identify the main sewer line
• Purchase a fittingly sized backflow valve
• While this installation is complex, a determined diver can:
• Cut the pipe and install the valve accord to manufacturer instructions
• Ensure the valve flap open in the direction of normal flow
• Secure with appropriate fittings and sealant

Note: this job oftentimes requires permits and may be wellspring leave to professionals.

Electrical and appliance protection

Elevate electrical components

Electrical systems and water don’t mix:

• Raise electrical outlets to at least 12 inches above potential flood levels
• Move circuit breaker panels to higher floors if possible
• Elevate air conditioning units, water heaters, and furnaces on concrete platforms
• Use waterproof electrical boxes for necessary ground level outlets

Emergency electrical measures

When flooding is imminent:
