Test your sump pump before the beginning of the rainy season
The most common time for a sump pump to fail is the first heavy rainfall after months of not being used. The submerged or partially submerged portions of cast iron pumps can rust and seize. And they'll burn out when they switch on. Don't get caught with your pump down and the water rising. After a long dry (unused) spell, pour a bucket or two of water into the sump to make sure the pump kicks on.
And do you have sump pump backup? A good sump pump installation should include a backup system for breakdowns and power outages. Learn the pros and cons of four pump backup methods here.

Add Inexpensive Door and Window Alarms
Attach the alarm to the door or window (with a screw or double-sided tape) alongside the magnetic contact strip (they don't have to be touching, but within 1/2 in.). When the door or window opens, breaking magnetic contact, the alarm shrieks (these little units have a piercing alarm). The door alarm has a delay feature, giving you time to set the alarm and leave, then open the door and deactivate the unit when you come home, without setting it off. The window unit has an on/off switch. The alarms will work on any door or window, and the batteries last two to three years.
